[0025] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0026] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0027] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a mobile device, etc. capable of realizing the above functions. The following takes a mobile device as an example to illustrate this embodiment and the following embodiments.

[0028] Based on this, the present application embodiment provides a hearing aid frequency response adjustment method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the hearing aid frequency response adjustment method of the present application.

[0029] It should be noted that this embodiment is applied to a mobile device, specifically a frequency response adjustment application in a mobile device, and the mobile device is communicatively connected with a hearing aid and a hearing aid charging box. The mobile device may be a smartphone, a tablet computer, or other portable electronic device. A hearing aid is an electronic device used to improve the hearing of a hearing-impaired person, and a hearing aid charging box is a device used to store and charge hearing aids. The mobile device has a built-in Bluetooth or other wireless communication module for establishing a communication connection with the hearing aid and the charging box.

[0030] In this embodiment, the hearing aid frequency response adjustment method includes steps S10 to S40: Step S10, when a preset detection instruction is received, a preset test audio is sent to the hearing aid charging box, wherein the hearing aid charging box receives the preset test audio and plays the preset test audio.

[0031] It should be noted that the user issues a preset detection instruction through a mobile device, and the triggering method may be by clicking a button in the application, a voice command, or other means. The preset detection instruction usually includes a command to start the test, and may also include some first test configuration information, such as the test environment, test duration, test speech speed, test phonemes, and test volume. The preset test audio usually includes pure speech and noisy speech, and the format can be a common audio file format (such as WAV, MP3, etc.). The mobile device and the hearing aid charging box transmit data through wireless communication (such as Bluetooth, Wi-Fi, etc.), and the preset test audio is transmitted to the hearing aid charging box, ready to be played by the hearing aid charging box. After receiving the preset test audio, the hearing aid charging box stores it in the internal memory and plays the preset test audio through the built-in speaker.

[0032] It can be understood that by playing preset test audio, the subject can hear and respond, so as to evaluate his hearing in different frequency ranges. The user can trigger the test process through a mobile device without the help of a professional. Moreover, due to the use of wireless communication technology, the preset test audio is sent and played in real time. The user can perform the test at different times and places, which improves the convenience of the test.

[0033] Step S20, receiving the response result of the test subject based on the played preset test audio in real time.

[0034] It should be noted that after hearing the preset test audio played, the subject provides the response result through the interface or method provided by the mobile device according to his or her hearing condition. The response result can be provided in a variety of ways, such as clicking a button on the screen, voice input, selecting an option in a drop-down menu, etc. Specifically, the subject needs to identify the played phonemes (such as "m", "u", "a", "i", "sh", "s", etc.) and select the correct option. The response result of each phoneme can be correct or wrong, and can also include uncertain or unheard situations. The subject can also provide a perception of the volume, such as "the sound is too low", "the sound is too loud", and provide a perception of the background noise, such as "the background noise is seriously disturbing". These options are helpful for subsequent adjustment of the volume setting and the first background noise type and intensity. The subject needs to provide a response result immediately after playing each phoneme, and the mobile device provides an interface for the subject to provide the response result. In addition, the mobile device needs to record the subject's response results in real time and store them in a local database or cloud server. For example, the response results can be stored in a local database in JSON (JavaScript Object Notation, JS key-value pair data) format, or synchronized to the cloud through an API (Application Programming Interface).

[0035] Step S30, performing frequency recognition rate analysis on the response result to determine the recognition rate within each frequency range.

[0036] It should be noted that the response result usually includes information such as phonemes, judgment results, volume perception and background noise perception. Each phoneme corresponds to one or more frequency ranges. For example: "m": low frequency (250Hz), "u": medium-low frequency (500Hz), "a": medium frequency (1000Hz), "i": medium-high frequency (2000Hz), "sh": high frequency (4000Hz), "s": high frequency (8000Hz). The frequency is divided into several preset frequency ranges, for example: low frequency (250Hz), medium-low frequency (500Hz), medium frequency (1000Hz), medium-high frequency (2000Hz), high frequency (4000Hz), high frequency (8000Hz). According to the frequency range corresponding to each phoneme, the response results are classified into the corresponding frequency range. For each frequency range, the recognition rate is calculated. The calculation formula of the recognition rate is: recognition rate = number of correct recognitions / total number of tests*100%.

[0037] It can be understood that by classifying and calculating the response results through scientific methods, the accuracy and reliability of the recognition rate analysis can be ensured, and the automated frequency recognition rate analysis can simplify the analysis process and improve efficiency.

[0038] In a feasible implementation, step S30 may include steps S31 to S33: Step S31, determining the phoneme corresponding to each option in the response result and the judgment result corresponding to each phoneme, wherein the response result is the option made by the subject on the mobile device for each phoneme played by the preset test audio.

[0039] It should be noted that phonemes are specific sound units played in the test audio, and the response result data usually includes information such as phonemes, options, judgment results, volume perception, and background noise perception. The judgment result is determined based on whether the option selected by the subject is consistent with the actual played phonemes, and the judgment result can be "correct" or "wrong".

[0040] Step S32, classifying each phoneme according to the frequency of each phoneme, and determining the phonemes within each preset frequency range and the corresponding judgment results.

[0041] It should be noted that each phoneme corresponds to one or more frequency ranges. These frequency ranges are usually predefined based on the acoustic characteristics of the phoneme. According to the frequency range corresponding to each phoneme, the response results are classified into the corresponding frequency range.

[0042] It can be understood that through the detailed classification results, users can clearly understand their listening performance in different frequency ranges, ensuring that each phoneme is correctly classified into the corresponding frequency range.

[0043] Step S33, calculating the recognition rate of each preset frequency range according to the judgment result corresponding to each phoneme in each preset frequency range.

[0044] It should be noted that, for each preset frequency range, the total number of tests and the number of correct recognitions of all phonemes within the range are counted, so as to calculate the recognition rate of each frequency range.

[0045] In this embodiment, by performing frequency recognition rate analysis on the response results and determining the recognition rate in each frequency range, accurate classification of the response results and precise calculation of the recognition rate are ensured, providing a reliable basis for subsequent gain adjustment and helping users understand the hearing conditions of the subjects in different frequency ranges.

[0046] Step S40, generating a gain configuration file of the hearing aid according to the recognition rate in each frequency range, and sending the gain configuration file to the hearing aid, wherein the hearing aid receives the gain configuration file and updates the gain configuration of each frequency range based on the gain configuration file.

[0047] It should be noted that the frequency range that needs to be adjusted is determined based on the recognition rate, and the increase or decrease in gain is determined. The specific amplitude of the gain adjustment is determined based on the difference in recognition rate. Generally, the lower the recognition rate, the greater the amplitude of the gain adjustment. The adjusted gain configuration is generated as a gain configuration file. The file format can be JSON, XML (Extensible Markup Language) or other suitable formats. The gain configuration file is sent to the hearing aid via wireless communication (such as Bluetooth, Wi-Fi, etc.). After receiving the gain configuration file, the hearing aid parses the file content and updates its own gain configuration according to the settings in the gain configuration file.

[0048] In a feasible implementation, step S40 may include steps A10 to A30: Step A10: determining a frequency range whose recognition rate is lower than a preset recognition threshold according to all recognition rates, and determining the frequency range whose recognition rate is lower than the preset recognition threshold as a target frequency range.

[0049] It should be noted that a preset recognition threshold may be set to determine the frequency range that requires gain adjustment. For example, a recognition rate of 80% is used as the preset recognition threshold, and gain adjustment is required for the frequency range with a recognition rate below 80%.

[0050] Step A20, calculating the difference between the recognition rate of each target frequency range and a preset recognition threshold, and determining the gain value of each target frequency range according to each difference.

[0051] The rule for gain adjustment can be referred to as follows: for every 10% decrease in recognition rate, the gain increases by 5dB, and for every 10% increase in recognition rate, the gain decreases by 2dB. Specifically, if the recognition rate of low frequency (250Hz) is 70%, and the current gain is 20dB, then the new gain = 20+5*((80-70) / 10) = 20+5*1 = 25dB; if the recognition rate of medium and high frequency (2000Hz) is 75%, and the current gain is 15dB, then the new gain = 15+5*((80-75) / 10) = 15+5*0.5 = 17.5dB; if the recognition rate of high frequency (4000Hz) is 60%, and the current gain is 25dB, then the new gain = 25+5*((80-60) / 10) = 25+5*2 = 35dB.

[0052] Step A30: Generate a gain configuration file according to the gain value.

[0053] It should be noted that the gain profile is usually in JSON or XML format. After generation, it is also necessary to check whether the generated gain profile meets the requirements of the hearing aid, for example, whether the gain value is within a reasonable range (0 to 100dB). The generated gain profile can be saved to local storage or uploaded to the cloud.

[0054] It can be understood that by generating a gain profile based on the recognition rate in each frequency range, it is ensured that the gain configuration of the hearing aid can accurately match the hearing condition of the subject. By generating and sending the gain profile through a mobile device, the user can easily adjust it without the help of a professional, thereby improving user convenience.

[0055] This embodiment sends a preset test audio to the hearing aid charging box when receiving a preset detection instruction, wherein the hearing aid charging box receives the preset test audio and plays the preset test audio; receives the response result of the subject in real time based on the played preset test audio; performs frequency recognition rate analysis on the response result to determine the recognition rate in each frequency range; generates a gain profile of the hearing aid according to the recognition rate in each frequency range, and sends the gain profile to the hearing aid, wherein the hearing aid applies the gain profile to update the gain configuration of the hearing aid. This embodiment simplifies the sending and playing process of the test audio through the communication connection between the mobile device and the hearing aid charging box, and receives the response result of the subject in real time. The user can directly operate on the mobile device, and automatically generate the gain profile through the frequency recognition rate analysis. The user can quickly obtain a personalized gain configuration and send the gain profile to the hearing aid through the mobile device, realizing the remote update of the hearing aid while avoiding the tedious process of manual adjustment by professionals. The user does not need to frequently go back and forth to the professionals, reducing the complicated steps and time cost, and greatly improving the convenience of frequency response adjustment of the hearing aid.

[0056] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 Before step S10, the hearing aid frequency response adjustment method further includes steps S01 to S03: Step S01, receiving first test configuration information input by a test subject, wherein the first test configuration information includes a test duration, a test speech rate, a test phoneme, and a test volume.

[0057] It should be noted that the test environment is, for example, a quiet indoor environment, a noisy outdoor environment, etc., the test duration is the total duration of the test, such as 5 minutes, 10 minutes, etc., the test speech speed is the playback speed of the test phonemes, such as slow, medium, and fast, the test phonemes include "m", "u", "a", "i", "sh", "s", etc., and the test volume is the volume of the test audio, such as moderate, large, and maximum.

[0058] Step S02: collecting first noise data of the current environment through a built-in microphone of the mobile device, and determining a first background noise type and a first noise intensity according to the first noise data.

[0059] It should be noted that features, such as spectral features, are extracted from the collected noise data, the noise types are classified using a pre-trained machine learning model (such as random forest), and the root mean square value is used to calculate the average intensity of the noise data.

[0060] Step S03: Generate a preset test audio according to the first test configuration information, the first background noise type and the first noise intensity.

[0061] It should be noted that the test environment will affect the volume and playback strategy of the test audio. For example, in a noisy environment, the volume may need to be increased to ensure that the user can clearly hear the test audio. The test duration determines the total length of the test audio, and it is necessary to ensure that the test audio is played within the set time. The test speech rate determines the playback speed of each phoneme, and the playback speed needs to be adjusted according to the user's choice. The test phoneme determines the specific content of the test audio, and the corresponding audio clip needs to be generated according to the user's choice. The test volume needs to be adjusted according to the background first noise intensity and the test environment to ensure that the user can clearly hear the test audio. The current gain configuration determines the degree of amplification of the hearing aid in different frequency ranges, and the frequency distribution of the test audio needs to be adjusted according to these gain configurations.

[0062] In a feasible implementation manner, the preset test audio includes pure speech and noisy speech, and step S03 may include steps B10 to B40: Step B10: Generate pure speech according to the first test configuration information.

[0063] It should be noted that the first test configuration information includes the test duration, test speech rate, test phonemes and test volume input by the user through the program interface. Continuous test audio can be generated according to the test phonemes, test speech rate and test duration, and then the overall volume of the audio can be adjusted according to the test volume to generate pure speech. In addition to being used to generate noisy speech, pure speech can also be used as a separate test audio and tested independently with noisy speech to ensure that the speech signal used in the test process is not interfered by any external noise, so as to accurately evaluate the performance of the hearing aid and the user's hearing condition.

[0064] Step B20: Select a preset background noise sample corresponding to the first background noise type.

[0065] It should be noted that preset background noise samples usually include but are not limited to the following: white noise, traffic noise, office noise, restaurant noise, natural noise, and industrial noise. The main purpose of selecting preset background noise samples is to simulate the real environment, ensure that the test conditions are as close as possible to the actual environment of the user's daily life, and test the noise reduction ability and speech clarity of the hearing aid under different background noises, so as to select the appropriate background noise samples according to the user's specific needs and usage scenarios. The preset background noise samples can be pre-recorded background noise samples, such as selecting pre-recorded background noise samples from a professional audio library, or using noise generation technology (such as noise synthesis algorithm) to generate background noise in real time. Any type of background noise can be generated as needed, with high flexibility, and multiple background noise samples can be mixed to simulate complex real environments.

[0066] Step B30: adjusting the noise volume of the preset background noise sample according to the first noise intensity.

[0067] It should be noted that the main purpose of adjusting the noise volume of the preset background noise sample is to ensure that the test conditions are as close as possible to the actual noise environment in the user's daily life, to test the noise reduction ability and speech clarity of the hearing aid under different first noise intensities, and to adjust the noise volume according to the user's specific needs and usage scenarios.

[0068] Step B40, superimposing a preset background noise sample of the noise volume onto the pure speech to generate a noisy speech.

[0069] It should be noted that superimposing the preset background noise samples of the noise volume onto the pure speech ensures that the noisy speech signal used in the test process can simulate the real listening environment, thereby more accurately evaluating the performance of the hearing aid and the user's hearing condition.

[0070] In a feasible embodiment, after step S40, step S50 may also be included: Step S50, determining first test configuration information, first background noise type and first noise intensity corresponding to the gain configuration file, and storing the gain configuration file, the first test configuration information, first background noise type and first noise intensity corresponding to the gain configuration file as historical gain configuration information.

[0071] It should be noted that the gain profile is generated based on the recognition rates of the aforementioned frequency ranges, and determining the recognition rates of the various frequency ranges requires several steps, such as generating a preset test audio, playing the preset test audio, and the subject's response. In these steps, it is necessary to obtain the first test configuration information, the first background noise type, and the first noise intensity to complete the step of generating the preset test audio. Therefore, each gain profile corresponds to a first test configuration information, a first background noise type, and a first noise intensity. Each gain profile, the first test configuration information, the first background noise type, and the first noise intensity are taken as a historical gain configuration information and stored in a mobile device, which can be used for subsequent quick response. For example, when a user enters a noisy restaurant, the hearing aid can automatically call the best gain profile in history in a similar environment to ensure that the user can immediately get the best hearing experience. If the user often uses the hearing aid in a traffic noise environment, the hearing aid can automatically call the best gain profile for traffic noise in history.

[0072] The hearing aid frequency response adjustment method also includes steps C10 to C40: Step C10, obtaining second test configuration information input by the test subject.

[0073] Step C20, collecting second noise data of the current environment through the built-in microphone of the mobile device, and determining the second background noise type and the second noise intensity according to the second noise data.

[0074] It should be noted that the second test configuration information, second noise data, second background noise type and second noise intensity here are the same type of data as the first test configuration information, first noise data, first background noise type and first noise intensity in steps S01~S02. The difference is that the former is used for quick matching through locally stored historical gain configuration information, while the latter is used to generate preset test audio and needs to undergo a series of tests.

[0075] Step C30, matching the second test configuration information, the second background noise type and the second noise intensity with the first test configuration information, the first background noise type and the first noise intensity in the historical gain configuration information to determine the historical gain configuration information that matches successfully.

[0076] It should be noted that all historical gain configuration information needs to be loaded from local storage. By matching the historical gain configuration information, the hearing aid can quickly call the previously optimized gain configuration file, reducing the time for reconfiguration and improving user convenience. For example, if the user is in a similar noisy environment again, the hearing aid can immediately call the previous best configuration to ensure that the user can immediately get the best hearing experience.

[0077] It can be understood that this step makes full use of historical gain configuration information to improve the intelligence level and adaptability of the hearing aid. By accumulating a large amount of historical data, the hearing aid can continuously optimize its algorithm and improve its performance in different environments.

[0078] Step C40: Obtain a gain configuration file in the successfully matched historical gain configuration information, and send the gain configuration file to the hearing aid, wherein the hearing aid receives the gain configuration file and updates the gain configuration of each frequency range based on the gain configuration file.

[0079] In the previous step C30, the historical gain configuration information of successful matching has been determined. Now it is necessary to extract the gain configuration file from the information and directly send the gain configuration file to the hearing aid for application.

[0080] Compared with the first embodiment, this embodiment can reduce the steps of regenerating preset test audio and testing subjects under the same environmental conditions based on historical adjustment data, and directly use the gain configuration file obtained historically to quickly adjust the frequency response, thereby greatly improving the adjustment efficiency.

[0081] This embodiment can record the user's hearing needs in different environments by storing the gain configuration file and its corresponding first test configuration information, the first background noise type and the first noise intensity as historical gain configuration information. As time goes by, the hearing aid can accumulate a large amount of historical gain configuration information to form a rich database. When the user is in a similar environment again, the hearing aid can quickly call the historical gain configuration information, reducing the reconfiguration time and improving user convenience.

[0082] This embodiment obtains first test configuration information input by the subject, collects noise data of the current environment through the built-in microphone of the mobile device, and determines the first background noise type and the first noise intensity corresponding to the noise data, determines the test audio parameters according to the first test configuration information, the current gain configuration, the first background noise type and the first noise intensity, and generates preset test audio according to the test audio parameters, optimizes the parameter settings of the test audio by collecting the noise data of the current environment and determining the first background noise type and intensity, generates test audio that conforms to the environment, and ensures the reliability and accuracy of the test results.

[0083] The present application embodiment provides a hearing aid frequency response adjustment method, referring to Figure 3 , Figure 3 This is a flow chart of a fourth embodiment of a method for adjusting the frequency response of a hearing aid of the present application.

[0084] It should be noted that this embodiment is applied to a hearing aid, and the hearing aid is connected to a mobile device and a hearing aid charging box. A hearing aid is an electronic device used to improve the hearing of a hearing-impaired person. The mobile device can be a smartphone, a tablet computer or other portable electronic device, and the hearing aid charging box is a device used to store and charge the hearing aid. The hearing aid has a built-in Bluetooth or other wireless communication module for establishing a communication connection with the mobile device and the charging box.

[0085] In this embodiment, the hearing aid frequency response adjustment method includes steps D10 to D20: Step D10, receiving the gain configuration file sent by the mobile device, wherein, when the mobile device receives the preset detection instruction, it sends a preset test audio to the hearing aid charging box, the hearing aid charging box receives the preset test audio, and plays the preset test audio; the mobile device receives the response result of the subject based on the played preset test audio in real time, performs frequency recognition rate analysis on the response result, determines the recognition rate within each frequency range, generates a gain configuration file of the hearing aid according to the recognition rate within each frequency range, and sends the gain configuration file to the hearing aid.

[0086] It should be noted that the hearing aid is equipped with a Bluetooth module or a WiFi module to achieve connection with the mobile device. The mobile device sends a gain configuration file to the hearing aid, and the gain configuration file is usually transmitted in JSON format. The steps of the mobile device refer to steps S10 to S40.

[0087] Step D20: updating the gain configuration of each frequency range based on the gain configuration file.

[0088] First, after receiving the gain configuration file, it is necessary to ensure that the gain configuration file has been correctly parsed and verified. The gain configuration file usually contains gain values ​​for each frequency range. The hearing aid needs to update the gain values ​​for each frequency range in it according to the parsed gain configuration file.

[0089] Understandably, the main purpose of hearing aids is to help users better understand and hear speech. Different frequency ranges have different effects on speech clarity. For example, consonants (such as s, sh, etc.) are mainly concentrated in the high frequency range, while vowels (such as a, e, i, etc.) are mainly concentrated in the mid-to-low frequency range. Through frequency response adjustment, the user's perception of consonants and vowels can be enhanced, and speech clarity can be improved. At the same time, everyone's hearing loss is unique, and the degree of hearing loss in different frequency ranges may be different. It is necessary to provide personalized gain compensation in different frequency ranges according to the user's hearing situation, so as to better meet the user's hearing needs. In addition, users will encounter different sound environments in different environments (such as quiet rooms, offices, streets, etc.). Frequency response adjustment can dynamically adjust the frequency response settings according to changes in the environment to adapt to different needs.

[0090] In this embodiment, the communication connection between the mobile device and the hearing aid charging box is used to simplify the process of sending and playing the test audio, and the test subject's response results are received in real time. The user can operate directly on the mobile device and automatically generate a gain profile through frequency recognition rate analysis. The user can quickly obtain a personalized gain configuration, and the hearing aid dynamically adjusts its frequency response setting according to the gain profile sent by the mobile device. While realizing remote updating of the hearing aid, the tedious process of manual adjustment by professionals is avoided. The user does not need to frequently travel back and forth to professionals, which reduces complicated steps and time costs, and greatly improves user convenience.
