The first electronic device 110 corresponds to the fitting end, and the second electronic device 120 corresponds to the user end.

[0039] The first electronic device 110 may be a desktop computer, laptop computer, PDA (Personal Digital Assistant), mobile phone, vehicle-mounted terminal, home theater terminal, dedicated terminal, intelligent voice interaction device, smart home appliance, or aircraft. Furthermore, it may be a single device or a collection of multiple devices.

In addition, it can be a single device or a collection of multiple devices.

[0041] Hearing aids 130 can be divided into air conduction hearing aids and bone conduction hearing aids according to the conduction method. According to the usage method, hearing aids can be divided into box type, glasses type, hairpin type, behind-the-ear type, in-the-ear type, in-the-ear type, and deep-in-the-canal type. There is no restriction on the type and brand of hearing aids 130 here.

[0043] The hearing aid method provided in the embodiment of the present application is implemented in the first electronic device 110. The first electronic device 110 receives connection status information sent by the second electronic device 120. The first electronic device 110 determines a first fitting parameter for fitting the hearing aid 130 based on the connection status information. The first electronic device 110 sends the first fitting parameter to the second electronic device 120, triggering the second electronic device 120 to fit the hearing aid 130 based on the first fitting parameter.

[0044] The hearing aid fitting method provided in the embodiments of the present application can be applied to various hearing aid fitting scenarios and can also be compatible with different hearing aid types. In some embodiments, the hearing aid fitting method provided in the embodiments of the present application can realize remote fitting of the hearing aid, that is, the distance between the first electronic device and the hearing aid is greater than the first distance threshold.

[0045] For ease of understanding, the application scenarios of the hearing aid fitting method provided by the embodiment of the present application are explained below. First, for users in remote geographical locations who cannot go to offline physical stores for fitting due to distance factors, the hearing aid fitting method provided by the embodiment of the present application can be adopted.

The entire fitting process is controlled by the first electronic device, which receives connection status information sent by the second electronic device, determines first fitting parameters for fitting the hearing aid based on the connection status information, and sends the first fitting parameters to the second electronic device, triggering the second electronic device to fit the hearing aid based on the first fitting parameters. The above examples do not limit the scope of protection of this case.

[0047] General description of the embodiments of this application

[0048] According to one embodiment of the present application, a hearing aid fitting method is provided. As shown in FIG2 , FIG2 is a flow chart of the hearing aid fitting method provided by the embodiment of the present application. The method can be applied to a hearing aid fitting device, which can be integrated into an electronic device, which can be a terminal, a server, or a combination of the two. The hearing aid fitting method can include:

[0049] Step 210: The first electronic device receives connection status information sent by the second electronic device.

[0050] The hearing aid fitting method provided in the embodiment of the present application is specifically operated by the fitting user (i.e., the fitting technician) on the first electronic device, which is equivalent to implementing the hearing aid fitting method provided in the embodiment of the present application on the first electronic device.

[0051] In the related art, hearing-impaired users are users who need to be fitted with hearing aids. This is only used to distinguish them from fitting users. Hearing-impaired users need to manually connect the second electronic device through the Bluetooth hearing aid, and the connection status between the second electronic device and the hearing aid is crucial to the fitting process of the hearing aid. If the connection status indicates that the connection between the second electronic device and the hearing aid has failed, the hearing aid cannot be fitted. If, during the fitting process of the hearing aid, the connection status indicates that the connection between the second electronic device and the hearing aid is disconnected, the fitting of the hearing aid will be interrupted, and the second electronic device and the hearing aid will need to be reconnected.

[0052] In the case where the distance between the first electronic device and the second electronic device is greater than the first distance threshold, that is, in the case where the distance between the fitting user and the hearing-impaired user is greater than the first distance threshold, the first electronic device cannot receive the fitting interruption information in time, and the fitting user cannot obtain the fitting interruption information.

[0053] In related technologies, the connection status affects the second electronic device's ability to receive hearing test audio, which can be referred to as hearing test material. Using fixed fitting parameters (including parameters such as the playback speed of the hearing test material) to perform hearing tests on hearing aid users can lead to inaccurate hearing test results (i.e., fitting results), which in turn can lead to inaccurate configuration parameters for the hearing aid. Inaccurate hearing aid configuration parameters can result in poor hearing performance for hearing-impaired users, potentially damaging the user's hearing.

[0054] In the hearing aid fitting method provided in the embodiments of the present application, the first electronic device can obtain connection status information in real time, allowing the fitting user to more quickly understand the connection status between the second electronic device and the hearing aid. Furthermore, during the hearing aid fitting process, the first fitting parameters for the hearing aid can be dynamically adjusted based on the connection status information. This is equivalent to fitting the hearing aid using fitting parameters adapted to the connection status between the second electronic device and the hearing aid. The hearing aid fitting method provided in the embodiments of the present application can avoid the problems existing in related technologies and improve the accuracy of hearing aid fitting.

[0055] In the embodiment of the present application, the second electronic device can be a smartphone, tablet device, or computer of a user who uses a hearing aid (i.e., a hearing-impaired user), and is not limited here. The hearing aid is a hearing aid that needs to be fitted. The hearing aid can be an unadjusted hearing aid purchased offline or online by the user. The hearing aid can also be a hearing aid that has been debugged for basic parameters and functions and requires parameter optimization at certain time intervals.

[0056] Connection status information indicates the connection status between the second electronic device and the hearing aid. The second electronic device and the hearing aid utilize short-range wireless communication. The connection status may include whether the connection between the second electronic device and the hearing aid is successful. If the connection is successful, the connection status information may include one or more parameters indicating the connection status. The following describes connection status information in conjunction with different short-range wireless communication technologies.

[0057] In some embodiments, the short-range wireless communication technology may be Bluetooth. Accordingly, when the connection is successful, the connection status information may include signal strength, connection interval, connection timeout, battery information, etc. Among them, the signal strength is represented by the received signal strength indicator (RSSI). The connection interval refers to the time interval for data transmission between the second electronic device and the hearing aid. The connection timeout refers to the maximum duration of the connection between the second electronic device and the hearing aid when no data is transmitted. The battery information can be the battery information of the second electronic device or the battery information of the hearing aid.

[0058] The following describes signal strength. The received signal strength indicator (signal strength) is measured in dBm and is generally negative, reflecting the degree of signal attenuation. In an ideal state with no attenuation, the signal strength can be 0 dBm. However, in actual use, even if the distance between the second electronic device and the hearing aid is less than the second distance threshold, and the second distance threshold is less than the first distance threshold, the signal strength can be -50 dBm, indicating that attenuation is present. In some embodiments, a signal strength greater than the first signal strength threshold can be set to indicate a stable connection. For example, a signal strength greater than -67 dBm can be set to indicate a stable connection.

[0059] For Bluetooth, factors that affect the Bluetooth signal strength between the hearing aid and the second electronic device include: the distance between the hearing aid and the second electronic device, physical obstacles between the hearing aid and the second electronic device (such as walls, buildings, etc.), multipath effect, other wireless devices within the preset range, electromagnetic interference sources, and other electronic devices within the preset range. The connection interval and connection timeout can be adjusted according to actual usage needs. Multipath effect refers to the signal forming multiple paths due to reflection, which may cause phase cancellation and thus reduce signal strength.

[0060] In some embodiments, the short-range wireless communication technology may be Wi-Fi, and the connection status information may include signal strength, signal-to-noise ratio (SNR), and connection rate. The SNR (Signal to Noise Ratio) is the ratio of signal strength to background noise level. A higher SNR indicates a more stable connection between the second electronic device and the hearing aid. The connection rate refers to the rate at which data is transmitted between the second electronic device and the hearing aid.

[0061] For Wi-Fi, factors affecting the signal strength and signal-to-noise ratio of the Wi-Fi connection between the hearing aid and the second electronic device include the distance between the hearing aid and the second electronic device, physical obstacles between the hearing aid and the second electronic device, other wireless devices within the preset range, and other electronic devices within the preset range. Factors also affecting the signal-to-noise ratio of the Wi-Fi connection between the hearing aid and the second electronic device include the selected channel. Factors affecting the connection speed between the hearing aid and the second electronic device include the signal-to-noise ratio, channel width, and the compatibility of the second electronic device and the hearing aid.

[0062] In some embodiments, the short-range wireless communication technology may be ZigBee, and the connection status information may include signal strength and network delay, wherein the network delay refers to the delay time for data transmission between the second electronic device and the hearing aid.

[0063] For ZigBee, factors that affect the ZigBee signal strength between a hearing aid and a second electronic device include the distance between the hearing aid and the second electronic device, physical obstacles between the hearing aid and the second electronic device, multipath effects, other wireless devices within the preset range, electromagnetic interference sources, and other electronic devices within the preset range. Factors that affect the ZigBee network latency between a hearing aid and a second electronic device include network latency, channel characteristics, and transmission mechanisms.

[0064] The following describes the manner in which the second electronic device sends connection status information. In some embodiments, the second electronic device may encapsulate the connection status information, and the first electronic device communicates with the second electronic device through a wireless data transmission channel, so that the first electronic device can receive the connection status information sent by the second electronic device.

[0065] In some embodiments, the wireless data transmission channel can be an instant messaging channel. Instant messaging channels are real-time and efficient. Instant messaging applications support online status display, which facilitates determining whether the other party is online and obtaining timely feedback. During the hearing aid fitting process, using the instant messaging channel, a first electronic device can instantly send fitting information to a second electronic device, and the first electronic device can also instantly obtain feedback from the second electronic device.

[0066] The information that can be transmitted by instant messaging includes binary information, plain text information, audio and video information, etc. The instant messaging channel is used to encapsulate, transmit and unpack messages between the second electronic device and the first electronic device, which can ensure low-latency communication and reliable message delivery. The communication protocol used by instant messaging can be Extensible Messaging and Presence Protocol (XMPP), Session Initialization Protocol (SIP), and Real-Time Messaging Protocol (RTMP). In some embodiments, the first electronic device and the second electronic device can both be the second electronic device of an online meeting.

[0067] In some embodiments, before the first electronic device receives the connection status information sent by the second electronic device, the method further includes:

[0068] A first electronic device sends a pairing request to a second electronic device, where the pairing request triggers the second electronic device to initiate a Bluetooth search. The pairing request can serve as a pairing instruction, meaning the first electronic device can send the pairing instruction to the second electronic device, and the second electronic device can initiate a Bluetooth search in response to the pairing instruction.

[0069] In some embodiments, the fitting request may be sent via an instant message. After receiving the fitting request sent by the first electronic device, the second electronic device decrypts and parses the fitting request, thereby initiating a Bluetooth search.

[0070] After initiating a Bluetooth search, the second electronic device can obtain one or more Bluetooth information within a preset range. The second electronic device can then return the one or more Bluetooth information to the first electronic device. The first electronic device can receive one or more Bluetooth information sent by the second electronic device, where the one or more Bluetooth information is the Bluetooth information searched when the second electronic device initiates a Bluetooth search.

[0071] In some embodiments, multiple Bluetooth information may be displayed on the display screen of the first electronic device, including Bluetooth information of the hearing aid. In response to a selection operation on the Bluetooth information of the hearing aid, a connection request is generated based on the Bluetooth information of the hearing aid.

[0072] When the multiple Bluetooth information includes the hearing aid's Bluetooth information, a connection request is generated based on the hearing aid's Bluetooth information and sent to the second electronic device, triggering the second electronic device to establish a Bluetooth connection with the hearing aid based on the hearing aid's Bluetooth information in the connection request. The connection request is equivalent to a Bluetooth connection instruction. In other words, the first electronic device can send the Bluetooth connection instruction to the second electronic device, and the second electronic device can then establish a Bluetooth connection with the hearing aid based on the Bluetooth connection instruction.

[0073] In some embodiments, after receiving the fitting request, the second electronic device may display a prompt message on the display screen of the second electronic device indicating that the second electronic device is establishing a Bluetooth connection with the hearing aid. The prompt message may also include information about the hearing aid. In this way, the user can obtain information about the hearing aid and that the hearing aid and the second electronic device are establishing a Bluetooth connection based on the prompt message.

[0074] In some embodiments, the prompt information may also include advice for improving the stability of the connection. The advice may be, for example, "Please move closer to the hearing aid." "Please move closer to the hearing aid" suggests that the user shorten the distance between the second electronic device and the hearing aid. The advice may also be, for example, "Keep away from physical obstacles and sources of electromagnetic interference." The advice may also be, for example, "Select a relatively quiet environment for fitting." The specific settings can be tailored to actual usage needs.

[0075] Accordingly, based on the recommended information, the user can consciously place the hearing aid to be fitted close to the second electronic device, away from physical obstacles and electromagnetic interference sources, and choose a relatively quiet environment for fitting, thereby improving the success rate of the first electronic device controlling the connection between the second electronic device and the hearing aid. For Wi-Fi and ZigBee, the above description can be equivalently replaced, that is, replacing Bluetooth with Wi-Fi or ZigBee, so that the first electronic device can control the connection between the second electronic device and the hearing aid.

[0076] In some embodiments, during the process of displaying the prompt message on the display screen of the second electronic device, any one of vibration and ringtone can be combined to prompt the user, thereby further improving the success rate of the first electronic device controlling the connection between the second electronic device and the hearing aid.

[0077] The following describes how to turn on the hearing aid. In some embodiments, the fitting user and the hearing-impaired user can make an audio call or a video call, so that the hearing-impaired user can turn on the hearing aid under the guidance of the fitting user, and then the hearing-impaired user can be guided to turn on the Bluetooth of the hearing aid.

[0078] In some embodiments, in the case where the fitting user and the hearing-impaired user can make an audio call or a video call, the fitting user can guide the hearing-impaired user to start the Bluetooth search function of the second electronic device, and the second electronic device can then search for nearby devices that are broadcasting.

[0079] In some embodiments, the second electronic device searches for broadcasts of nearby Bluetooth-enabled devices using the Generic Access Profile (GAP). The GAP is a sub-protocol defined in Bluetooth Low Energy (BLE) technology that defines how devices discover each other, establish connections, and implement binding. It also describes how devices can become broadcasters and observers, and implement connectionless data transmission. It also defines different types of addresses to protect data privacy and address resolvability.

[0080] In some embodiments, the second electronic device can send hearing aid information to the first electronic device. The hearing aid information can be one or more of a unique identification string of the hearing aid, the name of the hearing aid, and the model of the hearing aid. The first electronic device receives the hearing aid information sent by the second electronic device and sends an activation request to the hearing aid based on the hearing aid information. The hearing aid is further configured to activate Bluetooth based on the activation request.

[0081] After the second electronic device initiates a Bluetooth search, the second electronic device obtains Bluetooth information of Bluetooth-enabled devices within a preset range. The Bluetooth information may include Bluetooth names, Bluetooth addresses, and Bluetooth signal strengths. The second electronic device may obtain one or more pieces of Bluetooth information.

[0082] The Bluetooth address displayed by the second electronic device and the first electronic device should be expressed as 12 hexadecimal characters, with each character separated by a ":". For example, the Bluetooth address could be "00:0C:3E:3A:4B:69". The second electronic device encapsulates the Bluetooth information it searches for and sends it to the first electronic device as an instant message. The first electronic device receives the Bluetooth information sent by the second electronic device and may display the Bluetooth information in a pop-up window on the first electronic device.

[0083] In some embodiments, after receiving the packaged Bluetooth information, the first electronic device can decapsulate and parse the packaged Bluetooth information and display the parsed Bluetooth information on the first electronic device interface. In this way, the fitting user can intuitively obtain the Bluetooth information or the parsed Bluetooth information.

[0084] In some embodiments, a correspondence between Bluetooth information and hearing aids is pre-set. After obtaining the Bluetooth information, at least one of the name of the hearing aid, the image of the hearing aid, and the model of the hearing aid can be determined based on the Bluetooth information, and then at least one of the name of the hearing aid, the image of the hearing aid, and the model of the hearing aid can be displayed on the display interface of the first electronic device, thereby improving the richness of the content displayed on the display interface, and the fitting user can more intuitively know the hearing aid that needs to be fitted.

[0085] In some embodiments, when the multiple Bluetooth information include Bluetooth information of the hearing aid, the first electronic device sends a connection request to the second electronic device, and the second electronic device can establish a Bluetooth connection with the hearing aid based on the connection request.

[0086] In some embodiments, a Bluetooth list generated based on the plurality of Bluetooth information may be displayed on a display screen of the first electronic device, the Bluetooth list including Bluetooth information for the hearing aid, and a connection control may also be displayed on the display screen;

[0087] In response to a selection operation on the Bluetooth information of the hearing aid, the Bluetooth information of the hearing aid can be controlled to be in a selected state. Based on the Bluetooth information in the selected state, in response to a trigger operation on the connection control, a connection request can be generated based on the Bluetooth information of the hearing aid, and then the connection request can be sent to the second electronic device. The second electronic device can establish a Bluetooth connection with the hearing aid based on the Bluetooth information of the hearing aid in the connection request.

[0088] In some embodiments, after the first electronic device parses the received multiple Bluetooth messages, it displays the parsed Bluetooth messages in the form of a Bluetooth list to be connected on the fitting software interaction interface of the first electronic device.

[0089] In some embodiments, as shown in FIG3 , FIG3 is a schematic diagram of a first electronic device provided in an embodiment of the present application displaying a Bluetooth list. FIG3 shows a Bluetooth list, in which Bluetooth search results, i.e., multiple Bluetooth information, are displayed. FIG3 shows a device named “XXXXXXXXA”, whose corresponding Bluetooth address is “74:B3:D5:FD:12:B1”, and whose Bluetooth connection signal strength is “-73dBm”; a device named “XXXXXXXXB”, whose corresponding Bluetooth address is “A3:B1:35:0D:EB:8D”, and whose Bluetooth connection signal strength is “-92dBm”.

[0090] The fitting user can determine whether the Bluetooth list includes the hearing aid's Bluetooth information based on the Bluetooth name or Bluetooth address. If the Bluetooth list includes the hearing aid's Bluetooth information, in response to the fitting user's selection of the hearing aid's Bluetooth information, a connection request can be generated based on the hearing aid's Bluetooth information. The first electronic device can then send the connection request to the second electronic device, and the second electronic device can establish a Bluetooth connection with the hearing aid based on the hearing aid's Bluetooth information in the connection request.

[0091] If the Bluetooth list does not contain the Bluetooth information of the hearing aid, a search control can be displayed in the display interface of the first electronic device. In response to the triggering operation of the search control, a fitting request can be generated. Then the first electronic device can send the fitting request to the second electronic device, and the second electronic device can initiate a Bluetooth search again.

[0092] In some embodiments, in response to a connection request, the first electronic device may combine the hearing aid's Bluetooth information with signaling word information used for Bluetooth connection, encapsulate the combined information into binary or plain text format to obtain encapsulated information, and generate a connection request based on the encapsulated information. The first electronic device sends the generated connection request to the second electronic device via an instant message. The signaling word is a control signal that controls the communication process.

[0093] After receiving the connection request from the first electronic device, the second electronic device can decapsulate and parse the connection request to obtain the hearing aid's Bluetooth information and signaling information for the Bluetooth connection. Based on the hearing aid's Bluetooth information and signaling information for the Bluetooth connection, the second electronic device can establish a Bluetooth connection with the hearing aid in accordance with the GAP protocol.

[0094] In some embodiments, before the first electronic device sends the fitting request to the second electronic device, the hearing aid fitting method provided by the embodiment of the present application further includes:

[0095] The first electronic device receives a hearing aid fitting request sent by the second electronic device. The first electronic device may determine the hearing aid based on the hearing aid fitting request, which includes information about the hearing aid. After determining the hearing aid, the first electronic device may send a Bluetooth activation instruction to the hearing aid. The hearing aid may activate and broadcast a Bluetooth signal based on the Bluetooth activation instruction. In this way, the first electronic device can control the hearing aid to activate its Bluetooth.

[0096] In some embodiments, the hearing aid fitting request may include the hearing aid model, type, device number, and fitting software version of the second electronic device. After receiving the hearing aid fitting request, the first electronic device may determine the hearing aid that needs to have Bluetooth enabled.

[0097] In some embodiments, the first electronic device sends a fitting request to the second electronic device. After receiving the fitting request, the second electronic device may initiate a Bluetooth search and send a Bluetooth activation instruction to the hearing aid.

[0098] In some embodiments, as shown in Figure 4, Figure 4 is a schematic diagram of a first electronic device sending a fitting request to a second electronic device provided in an embodiment of the present application. The "Invite Object" control in the figure shows that the second electronic device has opened the fitting application software. In response to the trigger operation of the "Search Hearing Aid" control, the first electronic device can send a fitting request to the second electronic device, and the second electronic device can send a Bluetooth turn-on instruction to the hearing aid to turn on Bluetooth. The object second electronic device turns on the Bluetooth adapter and searches for devices with Bluetooth turned on within a preset range. The object is a hearing-impaired user. In this way, there is no need for the hearing-impaired user to manually turn on the Bluetooth of the hearing aid, thereby improving the fitting efficiency of the hearing aid and improving the user experience for the hearing-impaired user.

[0099] In some embodiments, the second electronic device can send a power-on command to the hearing aid based on the fitting application software, and the hearing aid can automatically turn on in response to the power-on command. In this way, the hearing-impaired user does not need to manually turn on the hearing aid to be fitted. The hearing aid can be controlled to turn on by the second electronic device, which can improve the user experience for the hearing-impaired user.

[0100] In some embodiments, the second electronic device sends a power-on command to the hearing aid via wireless communication, and the hearing aid starts up after receiving the power-on command. In some embodiments, when the second electronic device receives a fitting request, it can send a power-on command and a Bluetooth start-up command to the hearing aid via wireless communication, so that the hearing aid can receive the power-on command and the Bluetooth start-up command, turn on the hearing aid in response to the power-on command, and then turn on Bluetooth in response to the Bluetooth start-up command, that is, enter a mode of broadcasting Bluetooth signals.

[0101] After turning on Bluetooth, the hearing aid can send Bluetooth activation information to the second electronic device. The second electronic device can send the Bluetooth activation information to the first electronic device. After receiving the Bluetooth activation information, the first electronic device can display "The target hearing aid is turned on" in the form of a pop-up window on the display interface. It can also display "The target hearing aid is turned on and Bluetooth search can be performed" on the display interface. Of course, it can also play the above text.

[0102] If the hearing aid fails to turn on, or the hearing aid does not have Bluetooth enabled, a power-on failure message may be generated. In some embodiments, the power-on failure message may be sent by the hearing aid to the second electronic device, or may be automatically generated by the second electronic device after it does not receive feedback from the hearing aid within a preset time period. The second electronic device may then send the power-on failure message to the first electronic device, which may then display the power-on failure message and resend the fitting request. In this way, the fitting user can be informed of the progress of the hearing aid fitting in real time, thereby improving the accuracy of the hearing aid fitting.

[0103] In some embodiments, after the hearing aid turns on Bluetooth, it starts broadcasting Bluetooth information, which may include a Bluetooth name, a Bluetooth address, and a Bluetooth signal strength. The Bluetooth information may be sent to the second electronic device via the GAP protocol.

[0104] In some embodiments, after the hearing aid turns on Bluetooth, it can also send the device information of the hearing aid to the second electronic device via the GAP protocol. The device information of the hearing aid can include information such as the power level, language, and volume of the hearing aid.

[0105] The second electronic device transmits the hearing aid device information to the first electronic device via an instant messaging channel. The first electronic device can then send a corresponding prompt to the user regarding the current performance status of the hearing aid. For example, if the battery level is below a threshold, the first electronic device can generate a battery prompt message, such as: "Battery is low, please charge the hearing aid."

[0106] In some embodiments, as shown in FIG5 , FIG5 is another schematic diagram of a first electronic device sending a fitting request to a second electronic device provided in an embodiment of the present application. In this case, the fitting user can communicate with the hearing-impaired user through real-time video software or call software, and a prompt message can be displayed in FIG5 , which reads "Please communicate with the subject to turn on the hearing aid." The fitting user can guide the hearing-impaired user to turn on the hearing aid, thereby facilitating the first electronic device to control the Bluetooth connection between the second electronic device and the hearing aid.

[0107] In some embodiments, after the second electronic device is successfully connected to the hearing aid via Bluetooth, the interactive interface of the fitting application software of the first electronic device will be updated. As shown in Figure 6, Figure 6 is a schematic diagram of the first electronic device provided by the embodiment of the present application showing a successful Bluetooth connection. Figure 6 shows the connection status of the left-ear hearing aid and the right-ear hearing aid. The left-ear hearing aid and the right-ear hearing aid shown in Figure 6 are both in an optional state. In response to a selection operation for at least one of the left-ear hearing aid and the right-ear hearing aid, at least one of the left-ear hearing aid and the right-ear hearing aid is controlled to be in a selected state, and fitting can be performed on the hearing aid in the selected state. In other words, the embodiment of the present application can realize separate fitting for the left-ear hearing aid and the right-ear hearing aid, and can also realize joint fitting for the left-ear hearing aid and the right-ear hearing aid. It can be specifically set according to actual use requirements, which can improve the selectivity and accuracy of fitting of hearing aids.

[0108] In Figure 6, the remaining battery levels of the left and right hearing aids are also displayed, facilitating real-time battery monitoring. If the hearing-impaired user only wears a single hearing aid, the user's hearing aid can be selected, allowing fitting of the selected hearing aid.

[0109] In Figure 6, the device name "XXXXXXXXA" of the connected hearing aid to be fitted and the Bluetooth address "74:B3:D5:FD:12:B1" are also displayed. Click the icon corresponding to the left ear hearing aid and the icon corresponding to the right ear hearing aid to switch the left and right ears of the hearing aid, so that one ear or both ears can be fitted.

[0110] In some embodiments, FIG6 may further display multiple fitting controls, namely automatic audiometry 601, manual audiometry 602, parameter fitting 603, and user information 604. In response to a trigger operation for automatic audiometry 601, the hearing test mode may be automatically switched; in response to a trigger operation for manual audiometry 602, a hearing test may be performed manually; and in response to a trigger operation for parameter fitting 603, configuration parameters for the hearing aid may be set.

[0111] The automatic audiometry 601 is configured to perform hearing tests using computer technology and hearing test software. The automatic audiometry software provides a variety of test programs, such as pure tone audiometry, speech audiometry, and hearing tests in noise. Hearing-impaired users or fitting users can choose appropriate test programs based on actual conditions. The first electronic device automatically records the hearing threshold of the hearing-impaired user and draws a hearing test curve chart based on the test results.

[0112] Manual audiometry 602 is configured to allow the fitting user to gradually adjust the intensity and frequency of the audio played by the hearing aid according to the preset test process and requirements, obtain the response of the hearing-impaired user, record the hearing threshold and draw a hearing test curve.

[0113] User information 604 can be configured to view and record hearing test curves and hearing thresholds. It can also record the model of the hearing aid, the brand of the hearing aid, the age, gender, degree of hearing loss of the hearing-impaired user, etc., so that the fitting user can easily obtain the information of the hearing-impaired user corresponding to the hearing aid, thereby improving the accuracy of hearing aid fitting.

[0114] Step 220: Determine first fitting parameters for fitting the hearing aid based on the connection status information.

[0115] In some embodiments, an environment detection is performed based on the connection status information to obtain a detection result. If the detection result indicates that the environment meets the fitting condition, a first fitting parameter for fitting the hearing aid is determined based on the connection status information.

[0116] In some embodiments, it is possible to first determine whether the environment in which the hearing aid is located meets the fitting requirements. If the distance between the first electronic device and the second electronic device is greater than a first distance threshold, that is, when fitting the hearing aid remotely, the fitting user cannot predict and adjust the hearing-impaired user's environment (i.e., the hearing aid's environment), resulting in lower hearing aid fitting accuracy.

[0117] In order to improve the accuracy of fitting of hearing aids, when the connection turntable information includes the first signal strength, the first signal strength threshold of the hearing aid can be obtained, and environmental detection can be performed based on the first signal strength and the first signal strength threshold. When the first signal strength is greater than the first signal strength threshold, the detection result is determined to be that the environment meets the fitting conditions.

[0118] If the first signal strength is less than or equal to the first signal strength threshold, the detection result is determined to indicate that the environment does not meet the fitting condition. In this case, that is, if the detection result indicates that the environment does not meet the fitting condition, guidance information can be generated based on the connection status information. The guidance information is used to guide the adjustment of the relative position between the second electronic device and the hearing aid. The guidance information is sent to the second electronic device, triggering the second electronic device to display the guidance information. In some embodiments, the guidance information is suggestion information. For more information about the guidance information, please refer to the description of suggestion information.

[0119] In some embodiments, the first electronic device may set a first signal strength threshold in advance. The first signal strength threshold is a Bluetooth signal strength reference value, and the first signal strength is the signal strength of the Bluetooth connection between the hearing aid and the second electronic device. For example, the first electronic device may set the first signal strength threshold to -60dBm. After receiving the first signal strength of the Bluetooth connection between the hearing aid and the second electronic device, the first electronic device may automatically determine whether the first signal strength is greater than the first signal strength threshold.

[0120] In some embodiments, when the first signal strength is greater than the first signal strength threshold, it indicates that the Bluetooth connection stability is good at this time, and it is determined that the current fitting environment result meets the fitting requirements, and fitting can be performed.

[0121] If the first signal strength is less than the first signal strength threshold, it indicates that the Bluetooth connection between the hearing aid to be fitted and the target user is unstable. At this time, fitting may easily lead to disconnection of the Bluetooth connection, resulting in interruption of the fitting process. In this case, the fitting user can assist the hearing-impaired user in analyzing the reasons why the environment does not meet the fitting conditions.

[0122] In some embodiments, the first electronic device can send different guidance information to the second electronic device in sequence. For example, the first electronic device can first send guidance information 1 to the second electronic device. Guidance information 1 is used to guide the hearing-impaired user to bring the hearing aid closer to the second electronic device. The hearing-impaired user brings the hearing aid closer to the second electronic device.

[0123] The first electronic device can obtain the connection status information in real time. After the first period of time, if the connection status information indicates that the environment still does not meet the fitting conditions, the first electronic device can send guidance information 2 to the second electronic device. Guidance information 2 can be at least one of "stay away from physical obstacles", "stay away from electromagnetic interference equipment" and "stay away from noise". Of course, other guidance information can also be sent according to actual usage needs until the environment meets the fitting conditions. In this way, the first electronic device can determine whether the environment meets the fitting conditions through the connection status information received in real time, so that it can promptly detect the instability of the Bluetooth connection status, thereby improving the reliability of remote fitting of hearing aids. For the fitting conditions, please refer to the description of the parameters affecting each short-range wireless communication.

[0124] In the hearing aid fitting method provided in the embodiment of the present application, environmental detection can be performed based on the connection status information, so that through guidance information, the user can be guided to perform fitting in a quiet environment, guided to stay away from electronic devices with electromagnetic interference, and guided to stay away from obstacles such as walls, thereby improving the first signal strength and thus improving the reliability of remote fitting of hearing aids.

[0125] In some embodiments, the guidance information may be a posture adjustment instruction. When the detection result indicates that the environment does not meet the fitting conditions, a posture adjustment instruction for the relative posture between the second electronic device and the hearing aid may be generated, and the posture adjustment instruction may be sent to the second electronic device. The second electronic device may display the content corresponding to the posture adjustment instruction, or the second electronic device may play a posture adjustment prompt voice corresponding to the posture adjustment instruction.

[0126] In some embodiments, the relative posture between the second electronic device and the hearing aid includes the distance between the second electronic device and the hearing aid and the placement of the hearing aid relative to the second electronic device. The first electronic device generates a posture adjustment instruction for the relative posture between the second electronic device and the hearing aid to be fitted. The posture adjustment instruction is used to instruct the user to bring the hearing aid to be fitted closer to the second electronic device, or to adjust the placement of the hearing aid relative to the second electronic device.

[0127] After generating the posture adjustment instruction, the first electronic device encapsulates the posture adjustment instruction into binary information or plain text information and sends the posture adjustment instruction to the second electronic device via an instant messaging channel. After receiving the posture adjustment instruction, the second electronic device parses the posture adjustment instruction and displays the content corresponding to the posture adjustment instruction, or the second electronic device can play the posture adjustment prompt voice corresponding to the posture adjustment instruction.

[0128] In some embodiments, the connection status information may also include the packet loss rate between the second electronic device and the hearing aid, the data transmission rate between the second electronic device and the hearing aid, and the battery level. Signal strength and packet loss rate are used to characterize the stability of the Bluetooth connection. The data transmission rate affects the data transmission rate between the second electronic device and the hearing aid, and thus affects the data transmission rate between the second electronic device and the first device. When the data transmission rate slows down, the second electronic device cannot receive the fitting parameters and audio sent by the first electronic device in a timely manner.

[0129] When the first signal strength is weak (the first signal strength is less than or equal to the first signal strength threshold), the intensity of the audio sent by the first electronic device to the second electronic device, then transmitted by the second electronic device to the hearing aid and output by the hearing aid will also be weakened, or part of the audio is unclear, causing the user to be unable to understand the audio, and the audio playback speed will change.

[0130] When the first signal strength is weak (the first signal strength is less than or equal to the first signal strength threshold), there is a large difference between the audio data actually received by the second electronic device and the audio data output in the hearing aid and the audio data sent by the first electronic device, which ultimately leads to a decrease in the accuracy of the hearing test results (i.e., fitting results), hearing effect verification (i.e., verification of the effect of the configured hearing aid), and configuration of the hearing aid parameters, thereby reducing the accuracy of fitting the hearing aid.

[0131] If the test results indicate that the environment meets the fitting conditions, the first fitting parameter for fitting the hearing aid can be determined based on the connection status information. The first fitting parameter can be the audio playback speed, the audio frequency response, the audio reverberation effect, etc., which can be set according to actual usage requirements.

[0132] In some embodiments, a correspondence between the audio playback speed and signal strength is pre-set. Based on the first signal strength in the connection status information, the playback speed corresponding to the first signal strength can be determined, and then the playback speed corresponding to the first signal strength and the hearing test audio can be sent to the second electronic device. The second electronic device can send the playback speed corresponding to the first signal strength and the hearing test audio to the hearing aid.

[0133] In some embodiments, when the detection results indicate that the environment meets the fitting conditions, the reverberation effect corresponding to the connection status information can be determined based on the correspondence between the connection status information and the reverberation effect, so that the first electronic device can send the hearing test audio with the reverberation effect corresponding to the connection status information and the reverberation effect corresponding to the connection status information to the second electronic device, and the second electronic device can send the hearing test audio with the reverberation effect corresponding to the connection status information to the hearing aid.

[0134] When the test results indicate that the environment meets the fitting conditions, the connection status information may include the Bluetooth audio coding format. Based on the correspondence between the audio coding format and the frequency response, the frequency response corresponding to the audio coding format included in the connection status information can be determined, so that the first electronic device can send the hearing test audio with the frequency response corresponding to the audio coding format and the frequency response corresponding to the audio coding format to the second electronic device, and the second electronic device can send the hearing test audio with the frequency response corresponding to the audio coding format to the hearing aid.

[0135] The hearing aid can play the received hearing test audio, and the second electronic device can display feedback questions related to the hearing test audio. In response to the hearing-impaired user inputting answers to the feedback questions, the answers to the feedback questions can be obtained, and a fitting result can be generated based on the answers to the feedback questions. The feedback questions can be associated with the frequency response corresponding to the audio encoding format, the reverberation effect corresponding to the connection status information, and the playback speed corresponding to the first signal strength.

[0136] In some embodiments, the connection status information includes a first signal strength, and the step of "determining a first fitting parameter for fitting the hearing aid based on the connection status information" can be implemented as follows:

[0137] Obtain a second signal strength threshold and a second fitting parameter of the hearing aid; the second signal strength threshold may be the same as or different from the first signal strength threshold, and may be set according to actual usage requirements.

[0138] Determine a ratio of the first signal strength to the second signal strength threshold, and determine a first fitting parameter for fitting the hearing aid based on the ratio and the second fitting parameter. In some embodiments, the second fitting parameter includes a first playback speed of the hearing test audio. Based on the first playback speed and the ratio, a second playback speed of the hearing test audio can be determined, and the first fitting parameter for fitting the hearing aid is determined based on the second playback speed.

[0139] In some embodiments, the second signal strength threshold may be a reference Bluetooth signal strength, and the second signal strength threshold may be a signal strength value that can improve the accuracy of hearing aid fitting during the actual fitting process. Specifically, it may be set based on the fitting user's experience in remotely fitting hearing aids, or it may be set according to a unified signal strength standard in the field of hearing aid fitting.

[0140] For example, a second signal strength threshold of -50dBm can be used to meet the signal strength requirements for hearing aid fitting and facilitate the calculation of fitting parameters. After the first electronic device sets the second signal strength threshold, it can receive the first signal strength sent by the second electronic device and calculate the ratio of the first signal strength to the second signal strength threshold.

[0141] In some embodiments, the second fitting parameter includes a first playback speed of the hearing test audio (i.e., a reference playback speed). Based on the first playback speed and the ratio, the second playback speed of the hearing test audio can be determined. According to the second playback speed of the hearing test audio, the first fitting parameter for fitting the hearing aid can be determined.

[0142] In some embodiments, the hearing test audio refers to audio material used in a hearing test to assess the hearing level and comprehension ability of a hearing-impaired user. The hearing test audio generally includes the following types: pure tone signals, speech signals, ambient sounds, music signals, and noise signals.

[0143] The first playback speed of the hearing test audio refers to the most suitable playback speed for hearing-impaired users when the first signal strength is greater than the first signal strength threshold and the Bluetooth data transmission rate reaches a preset rate.

[0144] When the first signal strength is less than or equal to the first signal strength threshold, the hearing test audio takes a longer time to be transmitted and processed between the second electronic device and the hearing aid, so the playback speed of the hearing test audio transmitted to the hearing aid will also be reduced.

[0145] In some embodiments, the second playback speed of the hearing test audio is calculated based on the first signal strength and the first playback speed. The second playback speed can better match the hearing adaptability of the hearing-impaired user at the first signal strength, improve the accuracy of hearing aid fitting parameters, and enable the hearing-impaired user to achieve better hearing results.

[0146] In some embodiments, the first fitting parameter can be determined based on the relationship between the first signal strength and the second signal strength. When the first signal strength is greater than the second signal strength, the first playback speed can be left unchanged. For example, the second signal strength threshold is set to -60dBm, the first signal strength is -40dBm, and the first signal strength is greater than the second signal strength threshold, indicating that the current Bluetooth connection state is relatively stable and can ensure better transmission of the hearing test audio. The first playback speed can be left unchanged, that is, the first playback speed can be determined as the first fitting parameter.

[0147] In some embodiments, the second playback speed of the hearing test audio may be calculated based on the ratio of the first signal strength to the second signal strength threshold and the first playback speed of the hearing test audio. If the second signal strength threshold is -50dBm and the first signal strength is -75dBm, the first electronic device automatically calculates the ratio of the first signal strength to the second signal strength threshold to be two-thirds.

[0148] At this point, if the first signal strength is lower than the second signal strength threshold, the intensity of the hearing test audio transmitted from the first electronic device to the second electronic device and hearing aid will be weakened, causing some audio distortion during transmission. The hearing test audio transmitted to the second electronic device may contain noise. If the hearing test audio is played at normal speed, the hearing-impaired user will not be able to accurately reflect the content of the hearing test audio, resulting in inaccurate hearing comprehension tests of the hearing-impaired user in the hearing test results.

[0149] In order to improve the accuracy of fitting the hearing aid, the first playback speed can be adjusted based on the ratio of the first signal strength to the second signal strength threshold. Based on the ratio of the first signal strength to the second signal strength threshold, the first playback speed can be reduced by one third to obtain the second playback speed. Then, based on the second playback speed, the first fitting parameter for fitting the hearing aid can be determined.

[0150] For example, if the first playback speed is 1x, you can multiply 1 by two-thirds, which is equivalent to reducing the first playback speed by one-third, so that the second playback speed can be two-thirds. In this way, based on the relationship between the first signal strength and the second signal strength threshold, the first playback speed can be dynamically adjusted to obtain the second playback speed. Then, the second playback speed can be combined with one or more of the reverberation effect and the audio frequency response to obtain the first fitting parameter for fitting the hearing aid, thereby ensuring that the hearing-impaired user can better understand the hearing test audio and improve the accuracy of the hearing test results (fitting results).

[0151] In an embodiment of the present application, a first fitting parameter of the hearing aid that is more consistent with the connection status information can be obtained. The hearing aid can play the hearing test audio based on the first fitting parameter, thereby performing a hearing test on the hearing-impaired user, thereby obtaining a more accurate fitting result.

[0152] In some embodiments, the connection status information includes the third signal strength of the short-range wireless communication at the first moment and the fourth signal strength of the short-range wireless communication at the second moment. The first moment is earlier than the second moment. Of course, it can include signal strengths at multiple different moments. The number can be set according to actual usage requirements, which will not be elaborated here.

[0153] The difference between the third signal strength and the fourth signal strength is obtained. If the difference is greater than a difference threshold, first fitting parameters for fitting the hearing aid are determined based on the second signal strength. If the difference is less than or equal to the difference threshold, the first fitting parameters for fitting the hearing aid are determined based on the first signal strength. For details on how to determine the first fitting parameters, please refer to the above description. This method allows for more accurate fitting parameters to be obtained, thereby improving the accuracy of hearing aid fitting.

[0154] In some embodiments, the connection status information includes multiple fifth signal strengths, each with different fifth signal strengths at different times. An average of these multiple fifth signal strengths can be obtained, and then, based on the average fifth signal strength, a first fitting parameter for fitting the hearing aid can be determined. For specific determination methods, see the above description. This approach allows for more accurate fitting parameters to be obtained, thereby improving the accuracy of hearing aid fitting.

[0155] Step 230: Send the first fitting parameter to the second electronic device, triggering the second electronic device to fit the hearing aid based on the first fitting parameter.

[0156] In some embodiments, the first electronic device may send the first fitting parameters to the second electronic device, triggering the second electronic device to fit the hearing aid based on the first fitting parameters. In some embodiments, the first electronic device may send both the hearing test audio and the first fitting parameters to the second electronic device, and the second electronic device may send the hearing test audio and the first fitting parameters to the hearing aid, so that the hearing aid can play the hearing test audio based on the hearing test audio and the first fitting parameters.

[0157] In some embodiments, the first electronic device may only send the first fitting parameter to the second electronic device, the second electronic device may select the hearing test audio from the audio pre-stored in the second electronic device based on the first fitting parameter, and the second electronic device may send the hearing test audio and the first fitting parameter to the hearing aid, so that the hearing aid can play the hearing test audio based on the hearing test audio and the first fitting parameter.

[0158] In some embodiments, the first electronic device may receive the fitting results returned by the second electronic device, and the first electronic device may generate configuration parameters of the hearing aid based on the fitting results, and send the configuration parameters of the hearing aid to the second electronic device, triggering the second electronic device to configure the hearing aid based on the configuration parameters of the hearing aid.

[0159] In some embodiments, a hearing test can be performed on the hearing aid wearer, and the parameters of the hearing aid can be configured according to the results of the hearing test (i.e., the fitting results). The hearing test can include subjective audiometry and objective audiometry. The subjective audiometry method generally uses pure tones or languages ​​of different intensities and frequencies emitted by humans to measure the minimum intensity of sounds that can be heard by the human ear. The subjects express their reactions to the sound signals by complaints, gestures, or control indicator lights. This method includes: whisper test, stopwatch test, tuning fork test, pure tone audiometry, and language audiometry. The objective audiometry method uses the physiological reactions, acoustic impedance phenomena, and bioelectric phenomena caused by the subjects receiving the sound signals as indicators for judging the state of hearing function. This type of method is not affected by subjective factors, and the test results are more accurate.

[0160] In some embodiments, the first electronic device sends the first fitting parameter including the second playback speed of the hearing test audio to the second electronic device. After receiving the second playback speed, the second electronic device initiates the hearing test according to the second playback speed.

[0161] The fitting results can be obtained through the neural response or cochlear response of the hearing-impaired user's ear to the hearing test audio, or through real-time feedback from the user, such as verbal feedback and facial expression feedback, to determine whether the current test subject can hear sounds at normal volume, whether there is noise, whether the speed is appropriate, and whether the hearing is comfortable.

[0162] In some embodiments, the second electronic device sends the hearing test results to the first electronic device. The hearing test results are typically displayed in the form of a hearing test curve graph. In some embodiments, as shown in Figures 7 and 8, Figure 7 is a schematic diagram of a left ear hearing test result curve provided in an embodiment of the present application, and Figure 8 is a schematic diagram of a right ear hearing test result curve provided in an embodiment of the present application.

[0163] For Figures 7 and 8, the horizontal axis is the frequency of the sound, with Hertz (Hz). The vertical axis is the intensity of the sound, which can also represent the hearing level, with decibels (dB) as the unit, indicating the degree of hearing loss. The hearing test curve can characterize the hearing threshold of the test subject under sounds of different frequencies, and the fitting user can adjust the configuration parameters of the hearing aid according to the hearing test curve. In addition, the hearing test results can also include audiograms of the test subject undergoing air conduction tests and bone conduction tests, including some symbols representing the test results. For example, for a bone conduction test on the left ear, unmasked is indicated by ">" and masked is indicated by "]".

[0164] In some embodiments, the first electronic device may generate configuration parameters for the hearing aid based on the fitting results sent by the second electronic device. Configuration parameters may include: gain, frequency response, saturation sound pressure level, frequency range, noise suppression, etc. Gain represents the ability of the hearing aid to amplify sound. Depending on the degree of hearing loss, hearing aids with different gains can be used to compensate for hearing. In order to meet hearing requirements, hearing aids should provide a variety of different frequency responses. Different frequencies are reflected in the auditory sense as different tones. In order to make the frequency response of the hearing aid more consistent with the hearing loss characteristics of the hearing-impaired subject, some different tones are set on the tone adjustment knob.

[0165] The frequency range is the frequency range of sounds that the hearing-impaired can hear. If the hearing-impaired has poor hearing at a certain sound frequency, by adjusting the configuration parameters of the hearing aid, the hearing aid can compensate for the sound signal at this frequency and restore the hearing-impaired person's hearing at this sound frequency. The saturation sound pressure level is the maximum output power of the hearing aid. Setting an appropriate saturation sound pressure level can achieve the best hearing compensation effect for the hearing-impaired person and will not damage the user's hearing due to excessive output sound intensity. Noise suppression can suppress the noise generated by the hearing aid itself, or it can suppress noise interference in the surrounding environment. Adjusting the noise suppression parameters can enable the hearing-impaired person to hear the target sound more clearly.

[0166] In some embodiments, verification audio is determined based on the connection status information, and encoding parameters for the verification audio are determined. The verification audio is used to verify the effectiveness of the hearing aid after being configured using the configuration parameters. A verification request is generated based on the verification audio and the encoding parameters. In some embodiments, the verification audio is compressed based on the encoding parameters to obtain a compression result, and a verification request including the compression result is generated. The encoding parameters may include sampling rate, encoding rate, bit depth, etc.

[0167] The sampling rate is the number of times per second the audio signal is sampled for verification audio. The encoding rate is the amount of data transmitted or processed per unit time. The bit depth is the number of binary bits contained in each sample point. The sampling rate determines the frequency range and accuracy of the audio signal, the encoding rate determines the degree of compression and transmission efficiency of the audio data, and the bit depth determines the dynamic range and sound quality of the audio signal.

[0168] In some embodiments, a verification request is sent to a second electronic device, triggering the second electronic device to verify the effectiveness of the configured hearing aid based on the verification audio in the verification request. The above process can be repeated. The above processing for the verification audio can also be performed for the hearing test audio. Specifically, the corresponding content can be equivalently replaced, which is not detailed here.

[0169] In some embodiments, a verification result returned by the second electronic device may be received. The verification result may be obtained in the same manner as the fitting result. For details, please refer to the corresponding instructions and are not described in detail here. When the verification result indicates that the hearing aid is effective, the fitting process is terminated, which is equivalent to completing the fitting of the hearing aid.

[0170] When the verification result indicates that the hearing aid is poor, the fitting user can reset the configuration parameters of the hearing aid to obtain updated configuration parameters, and then send the updated configuration parameters to the second electronic device, so as to configure the hearing aid with the updated configuration parameters, and then execute based on the connection status information, determine the verification audio, generate a verification request based on the verification audio and encoding parameters, send the verification request to the second electronic device, and trigger the second electronic device to verify the effect of the configured hearing aid based on the verification audio in the verification request, until the verification result indicates that the hearing aid has a good hearing effect.

[0171] In some embodiments, after configuring the hearing aid according to the hearing aid's configuration parameters, the second electronic device can verify the hearing aid effectiveness of the configured hearing aid. The audio used to verify the hearing aid effectiveness can include speech, music, ambient sound, and ambient noise. During the actual verification process, appropriate verification audio can be selected based on actual hearing needs and the characteristics of the hearing aid.

[0172] The playback speed of the verification audio is updated based on the first signal strength. After the first electronic device determines the verification audio, it can generate a verification request based on the verification audio and the encoding parameters, and then send the verification request to the second electronic device. The verification request includes the compressed verification audio, that is, the compression result.

[0173] The second electronic device initiates hearing aid effectiveness verification on the hearing aid based on the compressed verification audio. In some embodiments, the signal strength varies. To improve the accuracy of hearing aid fitting, a second signal strength sent by the second electronic device can be periodically received. The second signal strength is sent by the second electronic device during the hearing aid fitting process based on the first fitting parameters.

[0174] Determine the difference between the second signal strength and the first signal strength. When the difference is greater than a preset difference threshold, generate a third fitting parameter. Send the third fitting parameter to the second electronic device, triggering the second electronic device to replace the first fitting parameter with the third fitting parameter. The method for generating the third fitting parameter can be equivalent to the method for generating the first fitting parameter, and is not further described here.

[0175] When the first signal strength changes, the first electronic device determines the verification audio and determines the encoding rate for the verification audio. During the verification audio transmission process, the verification audio can be encoded and compressed into an audio code stream, thereby reducing the amount of data in the verification audio, thereby reducing the cost of data transmission and storage. The encoding rate of the verification audio is the proportion of useful information in the audio code stream after the audio signal is sampled, quantized, and encoded. When the verification audio is transmitted to the second electronic device, the audio code stream is decoded to restore the original verification audio.

[0176] In an embodiment of the present application, a coding rate for encoding the verification audio can be determined based on the first signal strength. The coding rate is the coding rate at which the first electronic device sends the verification audio to the second electronic device. The coding rate can also be the coding rate at which the second electronic device sends the verification audio to the hearing aid.

[0177] In some embodiments, when the first signal strength is low, the encoding rate for encoding the verification audio can be reduced so that the hearing aid can receive the complete verification audio; when the Bluetooth signal strength is high, the encoding rate for encoding the verification audio can be increased, so that the hearing aid can obtain higher quality verification audio and obtain more accurate verification results.

[0178] In some embodiments, the verification of the hearing aid effect is to verify the output gain, frequency range, and noise reduction ability of the hearing aid, and to analyze the speech recognition ability of the hearing-impaired user after wearing the hearing aid. The analysis of the output gain of the hearing aid is mainly to verify whether the gain setting of the hearing aid matches the hearing loss level of the hearing-impaired user, and to analyze the frequency range to verify whether the hearing aid can meet the hearing loss at certain frequencies. The noise reduction ability can reflect the ability of the hearing aid to suppress its own noise and environmental noise, and verifying the speech recognition ability of the hearing-impaired user can analyze whether the hearing-impaired user can hear and understand the meaning expressed by the sound material. After the second electronic device verifies the hearing aid effect of the hearing aid, it obtains a hearing aid effect verification result (i.e., verification result). Like the hearing test results (fitting results) described in the above steps, the hearing aid effect verification result can also be represented by a hearing curve graph, and the second electronic device sends the obtained hearing aid effect verification result back to the first electronic device.

[0179] In some embodiments, the first electronic device receives the verification result of the hearing aid effect, and the fitting user analyzes the verification result. If the hearing aid effect verification result indicates that the hearing effect is good, for example, the output gain of the hearing aid can well compensate for the hearing loss of the hearing-impaired user and can better reduce the interference of noise. With the help of the hearing aid, the hearing-impaired user can well understand the information conveyed by others' speech. At this time, the fitting process can be terminated and the Bluetooth connection between the second electronic device and the hearing aid can be disconnected.

[0180] In some embodiments, periodically receiving the second signal strength sent by the second electronic device means receiving the second signal strength of the short-range wireless communication connection between the second electronic device and the hearing aid, which is returned by the second electronic device at predetermined intervals.

[0181] When it is detected that the difference is greater than the preset difference threshold, a third fitting parameter is generated, and the third fitting parameter is sent to the second electronic device, triggering the second electronic device to replace the first fitting parameter with the third fitting parameter.

[0182] In some embodiments, the second electronic device may transmit a second signal strength to the first electronic device at predetermined intervals, which may be seconds or minutes, without limitation. The first electronic device can determine the connection status between the second electronic device and the hearing aid based on the second signal strength, thereby preventing a sudden disconnection that could interrupt the fitting process.

[0183] In some embodiments, when the first electronic device receives the second signal strength, it subtracts the first signal strength from the second signal strength to obtain a difference. The magnitude of the difference can be used to detect the change in signal strength. If the second signal strength is lower than the first signal strength, the difference is subtracted from the first signal strength to obtain a difference. If the difference is greater than a preset difference threshold, it indicates that the current connection state is unstable and the fitting parameters need to be updated. If the difference is less than or equal to the preset difference threshold, it indicates that the connection state is stable and no fitting parameters need to be updated.

[0184] In some embodiments, the audio playback speed can be reduced. For example, if the first signal strength is -50dBm, the second signal strength is -60dBm, the preset difference threshold is 5dBm, and the difference between the first and second signal strengths is 10dBm, which is greater than the preset threshold, a third playback speed needs to be calculated using the method for calculating the second playback speed in the previous step, and a third fitting parameter is determined based on the third playback speed.

[0185] In some embodiments, if the second signal strength is greater than the first signal strength, the first signal strength is subtracted from the second signal strength to obtain a difference. If the difference is greater than a preset difference threshold, the connection is stable, and playing audio at a speed included in the first fitting parameter would result in an uncomfortable listening experience. If the difference is not greater than the preset difference threshold, there is no need to update the fitting parameters.

[0186] For example, if the first signal strength is -50dBm and the second signal strength is -40dBm, the difference is 10dBm, which is greater than the preset threshold of 5dBm. At this time, the fitting parameters need to be updated, such as appropriately increasing the playback speed. This method can obtain signal strength in real time and update fitting parameters based on signal strength, improving the accuracy of hearing aid fitting.

[0187] After the first electronic device generates the third fitting parameters, it can send them to the second electronic device. The second electronic device receives the third fitting parameters and continues fitting the hearing aid based on them. The fitting parameters can be automatically updated based on signal strength, improving the accuracy of the hearing test results and, consequently, the accuracy of the hearing aid fitting.

[0188] In the embodiment of the present application, a first electronic device controls a second electronic device to connect to a hearing aid, and then updates fitting parameters for the hearing aid according to the signal strength between the second electronic device and the hearing aid, and fits the hearing aid based on the fitting parameters. In this way, more accurate fitting results and verification results can be obtained, thereby obtaining a more precise configuration of the hearing aid and improving the accuracy of the hearing aid fitting system.

[0189] The embodiments of this application are described in detail in conjunction with specific application scenarios.

[0190] As shown in Figure 9, Figure 9 is a flow chart of a Bluetooth connection method provided by an embodiment of the present application. This embodiment will take the scenario of fitting hearing aids for hearing-impaired people in remote areas as an example and combine the execution entities of each step to describe the hearing aid fitting method in detail. The method of remotely controlling a second electronic device to connect to a hearing aid via Bluetooth by a first electronic device is as follows:

[0191] Before making a Bluetooth connection, the first electronic device can obtain user information such as the model, brand, and basic parameters of the hearing aid to be fitted, as well as the Bluetooth address corresponding to the hearing aid to be fitted, through the second electronic device. The touch key for the user information is displayed on the fitting application interface of the first electronic device. When searching for the hearing aid to be fitted in the list of available Bluetooth devices later, the fitting user can query the information of the hearing aid to be fitted by clicking the user information touch key.

[0192] The first electronic device sends a power-on instruction for the hearing aid to the second electronic device. The second electronic device controls the hearing aid to turn on according to the power-on instruction, and may also notify the user to turn on the hearing aid through real-time audio communication technology. After the hearing aid is turned on, it turns on Bluetooth broadcasting and broadcasts its own Bluetooth information to the outside. The first electronic device encapsulates the instruction to search for nearby Bluetooth devices into an instant message and sends it to the second electronic device. The second electronic device unpacks and parses the received instant message, turns on the Bluetooth adapter, and scans for nearby Bluetooth devices that are broadcasting. The second electronic device searches for nearby Bluetooth devices that are broadcasting through the GAP protocol and obtains the Bluetooth information of the surrounding Bluetooth devices.

[0193] In some embodiments, the second electronic device encapsulates the Bluetooth device information and sends it to the first electronic device in the form of an instant message. The first electronic device receives, unpacks, and parses the Bluetooth information, and displays a list of Bluetooth devices on the fitting software interface. If the Bluetooth device list contains the Bluetooth information of the hearing aid to be fitted, the first electronic device will initiate a Bluetooth connection instruction (i.e., a connection request) to connect to the hearing aid to be fitted, and send the Bluetooth connection instruction to the second electronic device via the instant messaging channel.

[0194] After receiving the Bluetooth connection command, the second electronic device parses the command information, obtains the Bluetooth address of the hearing aid to be fitted, and sends the Bluetooth connection command to the hearing aid to be fitted. The second electronic device connects to the designated hearing aid to be fitted according to the GAP protocol. The hearing aid to be fitted responds to the Bluetooth connection command from the second electronic device, establishes a low-power Bluetooth connection, and sends a Bluetooth response message to the second electronic device via the GAP protocol.

[0195] After the hearing aid to be fitted successfully responds to the Bluetooth connection status information from the second electronic device, the successful connection information is sent to the second electronic device via the GAP protocol. Upon receiving the successful Bluetooth connection information with the hearing aid to be fitted, the second electronic device's fitting application interface can display a message prompting the successful connection with the hearing aid to be fitted, and this information is packaged and returned to the first electronic device in the form of an instant message. The first electronic device receives the successful Bluetooth connection information between the second electronic device and the hearing aid to be fitted, displays the connection on the interactive interface, and displays the acquired basic information about the hearing aid to be fitted, such as the current remaining battery power of the hearing aid.

[0196] After the first electronic device controls the second electronic device to successfully establish a Bluetooth connection with the hearing aid, the first electronic device updates the fitting parameters for the hearing aid to be fitted based on changes in the Bluetooth signal strength information (i.e., signal strength), and performs a hearing test on the user by updating the fitting parameters. After the first electronic device receives the user's hearing test results (corresponding to the fitting results), it calculates the corresponding hearing aid configuration parameters based on the hearing test results and the Bluetooth connection signal strength information between the second electronic device and the hearing aid to be fitted. The first electronic device sends the calculated hearing aid configuration parameters to the second electronic device, and the second electronic device configures the hearing aid to be fitted based on the hearing aid configuration parameters.

[0197] As shown in FIG10 , FIG10 is another flowchart of the hearing aid fitting method provided in an embodiment of the present application. The hearing aid fitting method specifically includes the following steps:

[0198] Step 1010: The first electronic device obtains a first signal strength threshold, a first signal strength sent by the second electronic device, and a first playback speed of the hearing test audio.

[0199] In some embodiments, after a successful Bluetooth connection, the first electronic device obtains a first signal strength threshold, a first playback speed of the hearing test audio, and a first signal strength from the second electronic device. For example, if the first signal strength threshold is -50dBm, the first playback speed is 1x, and the first signal strength obtained from the second electronic device is -75dBm.

[0200] In some embodiments, the target user terminal can also send the battery power of the hearing aid to the first electronic device. When the battery power of the hearing aid is lower than the preset reference battery power, the first electronic device can initiate a reminder to charge the hearing aid to the target user terminal and perform real-time detection of the power of the hearing aid to ensure the integrity of the fitting process.

[0201] The first electronic device may also adjust the first signal strength threshold and the first playback speed according to the environment in which the hearing aid is located. Different first signal strength thresholds and first playback speeds may be set for different environments in which hearing aids are located.

[0202] For step 1010, please refer to the description of performing environmental detection based on the connection status information to obtain the detection result. When the detection result indicates that the environment meets the fitting conditions, the first fitting parameter for fitting the hearing aid is determined based on the connection status information. No further details are given here.

[0203] Step 1020: The first electronic device calculates a ratio of the first signal strength threshold to the first signal strength, and calculates a second playback speed based on the ratio and the first playback speed.

[0204] In some embodiments, the first signal strength threshold is equal to the second signal strength threshold, a ratio of the first signal strength threshold to the first signal strength is calculated, and a second playback speed of the hearing test audio is calculated based on the ratio and the first playback speed. The second playback speed of the hearing test audio may be a first fitting parameter for fitting the hearing aid.

[0205] In addition, the first electronic device can also adjust the encoding rate of the hearing test audio according to the first signal strength received from the second electronic device. When the first signal strength is less than or equal to the first signal strength threshold, the first electronic device can reduce the encoding rate of the hearing test audio to ensure that the hearing test audio can be transmitted completely to the second electronic device; when the first signal strength is greater than the first signal strength threshold, the first electronic device can appropriately increase the encoding rate of the hearing test audio, so that the second electronic device can receive clearer and higher-quality hearing test audio, thereby improving the user fitting experience.

[0206] In step 1030 , the first electronic device sends the first fitting parameter to the second electronic device, and sends a hearing test instruction to the second electronic device.

[0207] In some embodiments, the first electronic device sends the second playback speed and encoding rate to the second electronic device, and sends a hearing test instruction to the second electronic device. The hearing test instruction is used to instruct the second electronic device to control the hearing aid to perform a hearing test on the user based on the second playback speed and encoding rate (i.e., the first fitting parameters).

[0208] After receiving the hearing test instruction, the second electronic device initiates a hearing test on the hearing aid and sends the hearing test audio, encoding rate, and corresponding playback speed to the hearing aid, so that the hearing aid can perform a hearing test on the hearing-impaired user based on the hearing test audio, encoding rate, and playback speed. The first electronic device can store the fitting parameters debugged during the fitting process in the cloud and update and optimize the hearing aid fitting system based on the historical record of the hearing aid fitting parameter adjustments, thereby improving the responsiveness and working efficiency of the hearing aid fitting system.

[0209] In some embodiments, during the process in which the second electronic device initiates a hearing test of the subject to the hearing aid based on the fitting parameters, step 1030 further includes:

[0210] The first electronic device receives, at a preset time interval, a second signal strength of a Bluetooth connection between the second electronic device and the hearing aid, which is returned by the second electronic device;

[0211] When the first electronic device detects that the difference between the second signal strength and the first signal strength is greater than a preset threshold, the first electronic device generates a third fitting parameter;

[0212] The first electronic device sends a third fitting parameter to the second electronic device, and the second electronic device performs a hearing test on the subject based on the third fitting parameter sent by the first electronic device.

[0213] The first electronic device can dynamically adjust the fitting parameters according to the Bluetooth connection signal strength between the second electronic device and the hearing aid, which can reduce the problem of inaccurate hearing test results caused by unstable connection status, thereby improving the accuracy of the hearing aid fitting system.

[0214] Step 1040: The second electronic device performs a hearing test on the subject in response to the hearing test instruction, and returns the hearing test result to the first electronic device.

[0215] In some embodiments, after receiving the hearing test instruction from the first electronic device, the second electronic device initiates a hearing test on the hearing aid based on the fitting parameters. The hearing aid then performs the hearing test on the target user and generates a hearing test result. After the hearing test is completed, the second electronic device sends the collected hearing test result to the first electronic device, and the fitting user evaluates and analyzes the hearing test result.

[0216] In some embodiments, the first electronic device can also automatically generate a setting template for the configuration parameters of the hearing aid based on the hearing test results and the first signal strength, and automatically fill in the configuration parameters of the hearing aid recommended based on the hearing test results and the first signal strength, and display the hearing aid configuration parameter setting template on the fitting application software interface of the first electronic device. The fitting user then evaluates the rationality of the configuration parameters of the hearing aid automatically generated by the first electronic device to determine the configuration parameters of the hearing aid that ultimately need to be sent to the second electronic device.

[0217] In step 1050 , the first electronic device sets configuration parameters of the hearing aid according to the hearing test result, and sends the configuration parameters of the hearing aid to the second electronic device.

[0218] In some embodiments, a first electronic device receives a hearing test result sent by a second electronic device. After analyzing the hearing test result, the fitting user sets the configuration parameters of the hearing aid through the first electronic device. Alternatively, the first electronic device can analyze the hearing test result and generate corresponding configuration parameters of the hearing aid by itself. The fitting user then evaluates whether the configuration parameters of the hearing aid generated by the fitting software are reasonable. If there are unreasonable parameter settings, manual adjustments are made. For example, if the compensation gain of the hearing aid is set too high, it is easy to aggravate the hearing loss of the target user. In this case, the compensation gain of the hearing aid needs to be appropriately reduced.

[0219] The configuration parameters of the hearing aid may include parameters in terms of sound gain, volume setting, audio noise reduction, feedback suppression, etc. of the hearing aid. By adjusting the configuration parameters of the hearing aid, the hearing of the hearing-impaired user can be compensated to the greatest extent. There are many ways to set the configuration parameters of the hearing aid. For example, the fitting user manually inputs them into the first electronic device, or the fitting user selects the corresponding fitting parameter setting template in the software of the first electronic device. Both the first electronic device and the second electronic device support voice operation. The first electronic device can input the fitting parameters and the configuration parameters of the hearing aid by voice. After receiving the fitting parameters and the configuration parameters of the hearing aid sent by the first electronic device, the second electronic device can also play them to the user in the form of voice broadcast. In some embodiments, after the first electronic device generates the configuration parameters of the hearing aid, it packages the configuration parameters of the hearing aid and sends them to the second electronic device through an instant messaging channel.

[0220] Step 1060: The second electronic device receives the configuration parameters of the hearing aid sent by the first electronic device, and configures the hearing aid based on the configuration parameters of the hearing aid.

[0221] In some embodiments, the second electronic device receives and decrypts the hearing aid configuration parameters sent by the first electronic device, and transmits the hearing aid configuration parameters to the hearing aid via a Bluetooth wireless connection channel to configure the hearing aid. The hearing aid operates according to the input performance parameters to compensate for the user's hearing loss.

[0222] In step 1070 , the first electronic device determines the verification audio and the coding rate of the verification audio according to the connection status information between the second electronic device and the hearing aid, and sends the verification audio and the coding rate to the second electronic device.

[0223] In some embodiments, after the hearing aid has operated according to the set parameters for a certain period of time and the user has adapted to the current hearing aid operating mode, the first electronic device will detect the hearing aid's hearing effect, and the second electronic device will also send the current first signal strength between the second electronic device and the hearing aid to the first electronic device in real time. The first electronic device receives the first signal strength sent by the second electronic device and generates a verification audio. The playback speed of the verification audio is calculated and updated based on the Bluetooth connection signal strength.

[0224] When the Bluetooth connection signal strength (i.e., the first signal strength) is low (the first signal strength is less than or equal to the first signal strength threshold), the encoding rate of the verification audio can be reduced to ensure the stability of the transmission, so that the target user terminal can receive the verification audio completely; when the Bluetooth connection signal strength is high (the first signal strength is greater than the first signal strength threshold), the encoding rate of the verification audio can be increased, so that the user can obtain higher quality verification audio; when the Bluetooth connection signal strength maintains a relatively stable value, the first electronic device does not need to adjust the encoding rate of the verification audio. The first electronic device sends the verification audio and the set playback speed information and encoding rate to the second electronic device. In some embodiments, the first electronic device can also calculate the playback speed of the verification audio according to the method for calculating the playback speed of the hearing test audio in the aforementioned steps, so that the playback speed of the verification audio can be more adapted to the current Bluetooth connection signal strength, thereby accurately verifying whether the hearing aid speed of the current hearing aid can meet the actual needs of the user, so as to test and obtain accurate user hearing comprehension ability.

[0225] In step 1080, the second electronic device receives the verification audio sent by the first electronic device and initiates hearing aid effect verification for the hearing aid, obtains the hearing aid effect verification result and sends it to the first electronic device.

[0226] In some embodiments, after the second electronic device receives the verification audio and corresponding playback speed information sent by the first electronic device, it initiates a hearing aid effect verification instruction to the hearing aid. The hearing aid effect verification instruction may include the verification audio, playback speed, and encoding rate. After the hearing aid receives the hearing aid effect verification instruction sent by the second electronic device, it verifies the hearing aid effect for the target user based on the verification audio. During this process, the first electronic device can maintain contact with the user through real-time audio communication technology, such as video software, so that the fitting user can observe the user's facial expressions and body movements through the video software to obtain user feedback.

[0227] If the user experiences any discomfort during the hearing aid verification process, the user can be notified immediately through the video software, and the first electronic device terminates the hearing aid verification process. After the verification audio is played, the second electronic device receives the hearing aid verification result and sends it to the first electronic device.

[0228] Step 1090: The first electronic device receives the hearing aid effect verification result sent by the second electronic device. When the hearing aid effect verification result indicates that the hearing aid effect is good, the fitting process is terminated.

[0229] In some embodiments, the first electronic device receives the hearing aid effect verification result (i.e., verification result) returned by the second electronic device. The hearing aid effect verification result is analyzed by the fitting user, and the user is communicated with and receives real-time feedback from the user via video to determine whether the current hearing aid effect is good. Alternatively, the hearing aid effect verification result can be analyzed independently by the software of the first electronic device.

[0230] In some embodiments, the first electronic device can evaluate and analyze the verification results such as whether the hearing aid improves the hearing problems of the hearing-impaired user reflected in the hearing report under the current hearing aid configuration parameters, whether the hearing-impaired user can hear clear sounds, whether the content of the sounds and the information conveyed by the sounds can be correctly understood after hearing the sounds, whether the noise reduction function is good in noisy environments, and whether the feeling is comfortable during the listening process. When the hearing aid effect verification result indicates that the hearing aid effect is good, a message pop-up window is generated on the interactive interface (i.e., the display screen of the first electronic device), prompting the fitting user that the hearing aid effect verification result indicates that the hearing aid effect is good, the first electronic device can terminate the fitting process and send a message prompting the termination of the fitting process to the second electronic device. After receiving the message prompting the termination of the fitting, the second electronic device automatically disconnects the Bluetooth connection with the hearing aid; when the hearing aid effect verification result indicates that the hearing aid effect is not good, the first electronic device software prompts the fitting user that the hearing aid effect verification result indicates that the hearing aid effect is not good and needs to be re-fitted, and sends a message instruction to re-fit the hearing aid to the second electronic device, repeating the aforementioned hearing aid fitting steps.

[0231] In some embodiments, as shown in FIG11 , FIG11 is a schematic diagram of data transmission during the fitting process of a hearing aid provided by an embodiment of the present application, that is, data transmission performed by the first electronic device, the second electronic device, and the hearing aid after the Bluetooth connection between the second electronic device and the hearing aid is established and the fitting process begins. The transmission process is as follows:

[0232] In some embodiments, after establishing a Bluetooth connection between the hearing aid and the second electronic device, the first electronic device receives Bluetooth signal strength information (i.e., first signal strength) sent from the second electronic device via an instant messaging channel at regular intervals. After receiving the Bluetooth signal strength information, the first electronic device compares the current Bluetooth signal strength with a preset reference Bluetooth signal strength (i.e., first signal strength threshold). If the Bluetooth signal strength value at this time is not greater than the preset Bluetooth signal strength value, it indicates that the current fitting environment does not meet the fitting requirements. The first electronic device sends a posture adjustment instruction to the second electronic device. The posture adjustment instruction can be a text instruction, a voice instruction, or a graphic instruction, prompting the user to move the hearing aid device closer to the second electronic device, or away from physical obstacles and electromagnetic interference devices, to a quieter environment for testing and fitting. The user makes corresponding posture adjustments according to the prompts sent by the second electronic device until the Bluetooth connection signal strength received by the first electronic device meets the reference Bluetooth signal strength value. The first electronic device then sends an instruction to the second electronic device that the current fitting environment has met the fitting requirements and the hearing test is about to begin.

[0233] In some embodiments, if the Bluetooth signal strength value at this time is greater than the reference Bluetooth signal strength value, it indicates that the current fitting environment meets the fitting requirements, and the next fitting step, i.e., performing a hearing test on the user, can be performed. The first electronic device receives the Bluetooth signal strength information sent by the second electronic device and calculates the playback speed of the hearing test audio based on the ratio of the current Bluetooth signal strength to the reference Bluetooth signal strength. The calculation method of the playback speed has been explained in the previous step and will not be repeated here.

[0234] In some embodiments, the first electronic device may also adjust the encoding rate of the hearing test audio based on the current Bluetooth connection signal strength information. When the Bluetooth connection signal strength received by the first electronic device (i.e., the second signal strength) is lower than the Bluetooth connection signal strength received last time (i.e., the first signal strength), the first electronic device needs to reduce the encoding rate of the hearing test audio accordingly; when the Bluetooth connection signal strength received by the first electronic device is higher than the Bluetooth connection signal strength received last time, the first electronic device needs to increase the encoding rate of the hearing test audio accordingly; if the current Bluetooth connection signal strength is consistent with the Bluetooth connection signal strength received last time, the current encoding rate of the hearing test audio is maintained.

[0235] The first electronic device encapsulates the hearing test audio and the corresponding playback speed and encoding rate into an instant message and transmits it wirelessly to the second electronic device. The second electronic device initiates a hearing test to the hearing aid based on the received hearing test audio and playback speed, and sends the hearing test audio, playback speed, and encoding rate to the hearing aid. In the above process, the first electronic device receives the Bluetooth connection signal strength information (i.e., the second signal strength) between the second electronic device and the hearing aid at regular intervals, and calculates and updates the fitting parameters based on the Bluetooth connection signal strength information and the reference playback speed and reference encoding rate to obtain the target playback speed and target encoding rate of the hearing test audio under the current Bluetooth connection signal strength, thereby improving the accuracy of the hearing test results. The first electronic device sends the updated fitting parameters to the second electronic device to control the second electronic device to perform a hearing test on the user.

[0236] The second electronic device then sends the hearing test results to the first electronic device via an instant messaging channel. After receiving the hearing test results, the first electronic device analyzes them to determine the user's hearing loss level and the sound frequencies at which hearing loss is poor. The first electronic device then calculates hearing aid configuration parameters based on the analysis results and the current Bluetooth signal strength.

[0237] In some embodiments, the first electronic device sends the calculated hearing aid configuration parameters to the second electronic device via an instant messaging channel. The second electronic device receives the hearing aid configuration parameters sent by the first electronic device and configures the hearing aid according to the hearing aid configuration parameters. The second electronic device sends the hearing aid configuration parameters to the hearing aid via a Bluetooth wireless connection channel with the hearing aid. After the hearing aid configuration parameters are transmitted, the second electronic device sends a command to the first electronic device indicating that the hearing aid configuration parameters have been configured, as well as information about the current Bluetooth connection signal strength.

[0238] After the first electronic device receives the hearing aid configuration completion instruction sent by the second electronic device, it will proceed to the next fitting step, which is to verify the hearing aid effect of the current hearing aid. The first electronic device generates a verification audio based on the Bluetooth connection signal strength information transmitted back by the second electronic device, and calculates the encoding rate of the verification audio based on the current Bluetooth signal strength information. In addition, the first electronic device can also calculate the playback speed of the verification audio based on the ratio of the current Bluetooth connection signal strength and the reference Bluetooth signal strength. The method for calculating the playback speed of the verification audio is the same as the method for calculating the playback speed of the hearing test audio, which will not be repeated here. The first electronic device adjusts the playback speed and encoding rate of the verification audio by obtaining the Bluetooth connection signal strength information sent by the second electronic device, so as to obtain more accurate hearing aid effect verification results and enhance the user experience during the fitting process.

[0239] In some embodiments, the first electronic device can send the calculated verification audio, encoding rate, and corresponding playback speed to the second electronic device via an instant messaging channel. After receiving the verification audio, encoding rate, and playback speed, the second electronic device initiates a hearing aid effectiveness verification command to the hearing aid, which includes the verification audio, encoding rate, and playback speed. After the second electronic device completes the hearing aid effectiveness verification of the hearing aid, it sends the hearing aid effectiveness verification result to the first electronic device. The first electronic device receives and analyzes the hearing aid effectiveness verification result to determine whether the current hearing aid effectiveness meets the good performance criteria. If the current hearing aid effectiveness is good, the first electronic device sends a command to the second electronic device to terminate the fitting process. Simultaneously, the fitting information from the current fitting process, including hearing aid fitting parameters, user feedback, and the user's hearing test results, is uploaded to the cloud for storage. This allows the first electronic device to retrieve historical fitting information from the cloud and develop a fitting plan the next time a fitting is performed. After receiving the termination command, the second electronic device displays a message indicating that the current fitting effect is good, terminating the fitting process. Simultaneously, the second electronic device actively disconnects the Bluetooth connection with the hearing aid, completing the remote fitting of the hearing aid.
