Abstract
Description
Technical Field
[0001] The present invention relates to the field of audio processing, and more particularly to an audio compensation method for a Bluetooth headset, a Bluetooth headset, and a computer-readable storage medium. Background Art
[0002] With the widespread application of audio processing in civilian and commercial fields, audio processing, especially audio processing of Bluetooth headsets, is facing higher requirements.
[0003] Currently, in the audio processing of Bluetooth headsets, when users make calls via Bluetooth headsets, they will find that the downlink voice performance is not very clear, and the user will feel that the sound is a bit muffled. Especially during long online conference calls (which usually take 1 or 2 hours), users listening to vague, unclear and dull voices in Bluetooth headsets for a long time will significantly affect the user's call experience. Based on the results of the call survey, it is shown that one of the reasons for the difference in call performance (the call voice heard by the user) is the different hearing losses of different people. Some people feel that the far-end voice is muffled due to partial hearing loss at certain frequency points. This hearing loss is not significant and will not affect their daily life, but it will affect their call experience during Bluetooth voice communication.
[0004] Based on the above, there is a need for an audio compensation method for Bluetooth headsets that can achieve good audio playback, especially good call audio playback, and can perform good audio personalized compensation based on the hearing loss of different people through an audio compensation method for Bluetooth headsets, thereby improving the user's hearing experience, especially allowing the user to have a good call experience in personal calls.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of the present invention.
[0028] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.
[0029] Although the present application makes various references to certain modules in the system according to embodiments of the present application, any number of different modules can be used and run on the user terminal and / or server. The modules are illustrative only, and different aspects of the system and method can use different modules.
[0030] Flowcharts are used in this application to illustrate the operations performed by the systems according to the embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in exact order. Instead, the various steps may be processed in reverse order or simultaneously, as needed. Furthermore, other operations may be added to these processes, or one or more operations may be removed from these processes.
[0031] According to one aspect of the present disclosure, an audio compensation method 100 for a Bluetooth headset is proposed.
[0032] First, the Bluetooth headset is further described. The Bluetooth headset, for example, includes a pair of earphone components, and the pair of earphone components respectively correspond to the user's ears.
[0033] It should be understood that the Bluetooth headset can be, for example, a split Bluetooth headset, with two separate earphone components, each capable of being charged separately in a Bluetooth battery compartment. Alternatively, the Bluetooth headset can be a head-mounted Bluetooth headset, with the two earphone components connected via a headband. It should be understood that the embodiments of the present disclosure are not limited by the specific configuration or type of the Bluetooth headset.
[0034] Figure 1 FIG. 1 shows an exemplary flow chart of an audio compensation method 100 for a Bluetooth headset according to an embodiment of the present disclosure.
[0035] Reference Figure 1The method includes: in step S101, obtaining a monaural hearing loss curve corresponding to each ear of the user; wherein the monaural hearing loss curve corresponding to each ear of the user is generated based on a monaural hearing loss test performed on the corresponding ear of the user.
[0036] It should be understood that the monaural hearing loss curve corresponding to each ear of the user refers to the monaural hearing loss curve corresponding to the user's left and right ears (i.e., corresponding to different earphone components of the Bluetooth headset). The monaural hearing loss curve refers to a curve that characterizes the degree of hearing loss of a single ear (e.g., left ear or right ear) when performing a listening activity. For example, it may include the user's hearing loss data at multiple preset frequency points. However, it should be understood that the embodiments of the present disclosure are not limited to this.
[0037] It should be understood that the monaural hearing loss curve may be pre-generated and stored in the memory of the Bluetooth headset, or may be generated by performing a monaural hearing loss test on the user in real time before audio playback (e.g., a Bluetooth call). It should be understood that the embodiments of the present disclosure are not limited thereto.
[0038] For example, the above-mentioned acquisition of the monaural hearing loss curve corresponding to each ear of the user can be more specifically described as: for each headphone component, acquiring the monaural hearing loss curve of the corresponding ear of the user corresponding to the headphone component.
[0039] It should be understood that the monaural hearing loss test refers to testing the hearing loss degree of each ear of the user separately to obtain a monaural hearing loss curve.
[0040] The process of the monaural hearing loss test may, for example, include: for each ear of the user: detecting the hearing level of the ear at multiple preset frequencies to obtain the maximum inaudible volume of the ear at each preset frequency; determining the amount of hearing loss of the ear at each preset frequency based on the maximum inaudible volume of the ear at each preset frequency; and determining the monaural hearing loss curve based on the amount of hearing loss of the ear at each preset frequency.
[0041] However, it should be understood that the above is only an example process, and the embodiments of the present disclosure are not limited thereto.
[0042] In step S102, the original audio signal of the Bluetooth headset at the current moment is obtained.
[0043] It should be understood that the original audio signal of the Bluetooth headset at the current moment refers to the original audio signal that the Bluetooth headset is intended to transmit to the user at the current moment. Specifically, in a Bluetooth call scenario, the audio signal can be, for example, the original call signal; in an audio playback scenario, the audio signal can be, for example, the original audio signal. It should be understood that the embodiments of the present disclosure are not limited by the specific signal type of the original audio signal.
[0044] For example, obtaining the original audio signal of the Bluetooth headset at the current moment, for example, can be obtaining the original audio signals that the two earphone components of the Bluetooth headset are intended to transmit at the current moment, that is, obtaining the original audio signal of each earphone component in the two earphone components at the current moment; or if only a single earphone component is currently used, for example, it can be obtaining the original audio signal that the single earphone component is intended to transmit at the current moment.
[0045] The original audio signal, used to distinguish it from the compensated audio signal mentioned below, refers to an audio signal that has not been subjected to the audio compensation process in this application. It should be understood that the embodiments of the present disclosure are not limited by the signal type or signal content of the original audio signal.
[0046] It should be understood that the aforementioned steps S101 and S102 can be executed sequentially, or in reverse order, or simultaneously. The embodiments of the present disclosure are not limited by the specific execution order of the steps S101 and S102.
[0047] In step S103, based on the monaural hearing loss curve corresponding to each ear of the user, compensation processing is performed on the original audio signal of the Bluetooth headset at the current moment to generate a compensated audio signal.
[0048] The compensation processing refers to a process of compensating the original audio signal (eg, compensating the volume value of the audio signal) and / or adjusting the original audio signal (eg, reducing the volume of the audio signal that obviously exceeds the maximum volume range).
[0049] The compensation processing includes, for example, performing compensation processing on the original audio signal of each earphone component of the Bluetooth earphone at the current moment based on the monaural hearing loss curve to generate a compensated audio signal.
[0050] It should be understood that the above only provides an example of the audio compensation processing process, and the embodiments of the present disclosure are not limited thereto.
[0051] Based on the above, in the present application, by setting up an audio compensation method for a Bluetooth headset, the original audio signal of the Bluetooth headset at the current moment is obtained; a monaural hearing loss curve corresponding to each ear of the user is obtained; based on the monaural hearing loss curve corresponding to each ear of the user, the original audio signal of the Bluetooth headset at the current moment is compensated to generate a compensated audio signal; and the monaural hearing loss curve corresponding to each ear of the user is set to be generated based on a monaural hearing loss test of the ear of the user, so that in a simple and convenient manner, the audio compensation method for the Bluetooth headset can be used for each person based on the hearing loss of different people, and the audio signal can be well personalized in accordance with the monaural hearing loss curve, thereby improving the user's auditory experience, especially allowing the user to have a good call experience in personal calls.
[0052] In some embodiments, the process of generating a monaural hearing loss curve for each ear of a user based on performing a monaural hearing loss test on the corresponding ear of the user can be described in more detail. Figure 2 An exemplary flow chart of a process 200 for generating a monaural hearing loss curve for each ear of a user according to an embodiment of the present disclosure is shown.
[0053] Reference Figure 2 In the process of generating a monaural hearing loss curve, first, in step S201, for each ear of the user, the hearing level of the ear at multiple preset frequencies is detected to obtain the maximum inaudible volume of the ear at each preset frequency.
[0054] The preset frequency points refer to a plurality of preset frequency points, which may be, for example, 250 Hz, 500 Hz, or 5000 Hz, 8000 Hz, etc. It should be understood that the embodiments of the present disclosure are not limited by the specific frequency values of the preset frequency points.
[0055] The preset frequency points may be, for example, three or eight. The preset frequency points may be, for example, continuous frequency points, or may be equally spaced frequency points or unequally spaced frequency points as needed. It should be understood that the embodiments of the present disclosure are not limited by the number of the preset frequency points or the distribution of the preset frequency points.
[0056] The maximum inaudible volume at each preset frequency point refers to the lower limit volume when the user listens to the audio signal at that frequency point. That is, the user can only hear the audio signal when the volume of the audio signal is greater than the maximum inaudible volume. When the volume of the audio signal is equal to or lower than the maximum inaudible volume, the user will not be able to hear the audio signal.
[0057] Detecting the hearing level of the ear at multiple preset frequencies can be accomplished, for example, by playing a preset audio signal at the preset frequency to the ear (e.g., the volume of the audio signal changes from high to low), and determining the user's hearing level by obtaining hearing level feedback from the user (e.g., different user inputs or different gestures, etc.). The hearing level here is represented by the maximum inaudible volume of the user at the preset frequency. It should be understood that the lower the maximum inaudible volume at the preset frequency, the higher the user's hearing level at the frequency.
[0058] For example, the process of detecting the hearing level of the ear at multiple preset frequency points to obtain the maximum inaudible volume of the ear at each preset frequency point may include: at each preset frequency point: playing a preset audio signal corresponding to the preset frequency point to the user through the corresponding headphone component, wherein the volume of the preset audio signal decreases from a preset maximum volume to a preset minimum volume according to a preset rule; obtaining hearing level feedback from the user, and determining the maximum inaudible volume of the ear at the preset frequency point based on the hearing level feedback.
[0059] However, it should be understood that the above is only an example of a process for obtaining the maximum inaudible volume at a preset frequency point, and the embodiments of the present disclosure are not limited thereto.
[0060] Thereafter, in step S202 , the amount of hearing loss of the ear at each preset frequency is determined based on the maximum inaudible volume of the ear at each preset frequency.
[0061] It should be understood that the amount of hearing loss refers to the amount of hearing loss in the user's ear at the preset frequency, which can be represented, for example, as the volume loss (unit: decibel). For example, it can represent the volume range over which the user cannot hear the sound normally when the preset audio signal at the frequency is reduced from a preset maximum volume to a preset minimum volume. The amount of hearing loss can be determined, for example, based on the maximum inaudible volume.
[0062] For example, if a preset audio signal corresponding to each preset frequency is played to the user through the corresponding headphone component at each preset frequency, where the volume of the preset audio signal decreases from a preset maximum volume to a preset minimum volume according to a preset rule, then based on the preset minimum volume of the preset audio signal at the preset frequency and the maximum inaudible volume of the preset frequency (for example, subtracting the maximum inaudible volume from the preset minimum volume), the amount of hearing loss at the preset frequency can be determined.
[0063] However, it should be understood that the above only provides one method for determining the amount of hearing loss, and the embodiments of the present disclosure are not limited thereto.
[0064] After the hearing loss amount is determined, in step S203 , the monaural hearing loss curve is determined based on the hearing loss amount of the ear at each preset frequency point.
[0065] For example, a curve graph can be drawn based on each preset frequency point and the hearing loss amount corresponding to the preset frequency point, where the horizontal axis is each preset frequency point and the vertical axis is the hearing loss amount corresponding to the preset frequency point, thereby obtaining a monaural hearing loss curve.
[0066] Based on the above, in the present disclosure, in the process of generating a monaural hearing loss curve for each ear of the user, for each ear of the user: the hearing level of the ear at multiple preset frequencies is tested to obtain the maximum inaudible volume of the ear at each preset frequency; the amount of hearing loss of the ear at each preset frequency is determined based on the maximum inaudible volume of the ear at each preset frequency; and the monaural hearing loss curve is determined based on the amount of hearing loss of the ear at each preset frequency. In this way, in the process of generating the monaural hearing loss curve, the maximum inaudible volume of each ear of the user at each preset frequency can be individually tested, and the amount of hearing loss can be determined based on the maximum inaudible volume at multiple preset frequencies. The resulting monaural hearing loss curve can well represent the hearing level of the user's monaural ear at each different frequency, thereby facilitating subsequent corresponding compensation of the original audio signal based on the monaural hearing loss curve, thereby improving the user's auditory experience.
[0067] In some embodiments, the aforementioned step S201 of detecting the hearing level of the ear at a plurality of preset frequencies to obtain the maximum inaudible volume of the ear at each preset frequency may be described in more detail. Figure 3 An exemplary flowchart of the process S201 of obtaining the maximum inaudible volume of the ear at each preset frequency point according to an embodiment of the present disclosure is shown.
[0068] Reference Figure 3 In step S2011, at each preset frequency point: a preset audio signal corresponding to the preset frequency point is played to the user through the corresponding earphone component, wherein the volume of the preset audio signal decreases from a preset maximum volume to a preset minimum volume according to a preset rule.
[0069] The preset audio signal may be, for example, an audio signal having a preset frequency point. The embodiments of the present disclosure are not limited by the specific content and presentation method of the audio signal.
[0070] The preset maximum volume refers to the maximum volume of the audio signal, and the preset minimum volume refers to the minimum volume of the audio signal. It should be understood that the maximum and minimum volumes can be set according to actual needs, and different maximum and / or minimum volumes can be used for different frequency points, for example, but the embodiments of the present disclosure are not limited thereto.
[0071] For example, depending on different application scenarios, when the purpose is to compensate for call audio signals, the preset maximum volume of each preset audio signal can be set to 40dB and the preset minimum volume to 1dB, so that the test volume is more closely aligned with the volume state in the call scenario. However, the embodiments of the present disclosure are not limited thereto.
[0072] The volume of the preset audio signal decreases from a preset maximum volume to a preset minimum volume according to a preset rule. For example, the preset maximum volume of the preset audio signal is 90 decibels, the preset minimum volume is 0 decibels, and the preset audio signal can be set to decrease from the maximum volume to the minimum volume at a preset volume interval of 5 decibels, and each volume interval lasts for 2 seconds. In this case, the preset audio signal is first played at 90 decibels for 2 seconds, then played at 85 decibels for 2 seconds, and finally dropped to 0 decibels.
[0073] However, it should be understood that the above merely provides an example of setting the volume of the audio signal to decrease from a preset maximum volume to a preset minimum volume according to a preset rule, and the embodiments of the present disclosure are not limited thereto.
[0074] Thereafter, in step S2012, hearing level feedback from the user is obtained, and the maximum inaudible volume of the ear at the preset frequency is determined based on the hearing level feedback.
[0075] It should be understood that the user's hearing level feedback refers to a feedback signal used to provide feedback on the user's hearing level at the current preset frequency point. Depending on actual needs, it can be, for example, a gesture signal, a voice signal, or an information signal input by the user. The embodiments of the present disclosure are not limited to the specific feedback signal type of the hearing level feedback.
[0076] It should be understood that, for example, the maximum inaudible volume can be directly determined based on the user's hearing level feedback, or the maximum inaudible volume can be obtained by processing based on a preset algorithm based on the user's hearing level feedback.
[0077] For example, when testing the user's left ear, a preset audio signal corresponding to a preset frequency can be played to the user via the earphone component corresponding to the left ear in the Bluetooth headset, and the user can provide feedback by, for example, continuously pressing the external touch surface of the earphone component. For example, when the volume of the preset audio signal decreases from a preset maximum volume to a preset minimum volume according to a preset rule, if the user continuously presses the external touch surface of the earphone component, it indicates that the user can hear the volume of the sound at the frequency. When the user's hand no longer touches the external touch surface of the earphone component, it indicates that the user cannot hear the preset audio signal at the volume. However, it should be understood that the embodiments of the present disclosure are not limited to this.
[0078] Based on the above, in the present disclosure, when the maximum inaudible volume of the ear at each preset frequency is obtained by setting, at each preset frequency, a preset audio signal corresponding to the preset frequency is first played to the user through the corresponding headphone component, wherein the volume of the preset audio signal decreases from a preset maximum volume to a preset minimum volume according to a preset rule; then, hearing level feedback from the user is obtained, and the maximum inaudible volume of the ear at the preset frequency is determined based on the hearing level feedback, so that the embodiments of the present disclosure can accurately and reliably determine the maximum inaudible volume of the user's ear at each preset frequency in a simple and convenient manner, which is conducive to the subsequent generation of a monaural hearing loss curve based on the maximum inaudible volume.
[0079] In some embodiments, the volume of the preset audio signal decreases from a preset maximum volume to a preset minimum volume at a preset volume interval.
[0080] The preset volume interval value refers to the decibel value by which the volume is reduced during a single volume reduction. For example, the preset volume interval value can be set to 3dB to better match the minimum audible change (the minimum change in sound pressure level that the human ear can perceive), or it can be set to 4dB, 6dB, etc., depending on actual needs. It should be understood that the embodiments of the present disclosure are not limited to the specific values of the preset volume interval values.
[0081] For example, when the volume of the preset audio signal is set to decrease by 3dB from a preset maximum volume of 100dB to a preset minimum volume of 1dB, and each volume is set to last for one second, the volume change of the preset audio is, for example, 100dB-97dB-94dB-91dB...-1dB.
[0082] By setting the volume of the preset audio signal to decrease from a preset maximum volume to a preset minimum volume at a preset volume interval value, the step size of the volume reduction can be adjusted according to actual conditions. On the one hand, the amplitude of the volume reduction satisfies the minimum audible hearing change of the human ear, and the change in the audio volume can be perceived by the human body in a timely manner. On the other hand, the step size of the volume reduction can be set according to actual conditions, thereby improving the accuracy of the maximum inaudible volume detected.
[0083] In some embodiments, the process S2012 of obtaining hearing level feedback from the user and determining the maximum inaudible volume of the ear at the preset frequency based on the hearing level feedback can be described in more detail.
[0084] For example, when obtaining first hearing level feedback from the user, the current volume of the preset audio signal is not recorded. When obtaining second hearing level feedback from the user, the current volume of the preset audio signal is recorded and determined as the maximum inaudible volume at the preset frequency. The first hearing level feedback is different from the second hearing level feedback.
[0085] The first and second hearing level feedback signals are used to provide feedback on the user's hearing level at the current preset frequency. Specifically, the first hearing level feedback indicates that the user has good hearing for the preset frequency signal at the current volume; the second hearing level feedback indicates that the user has poor hearing for the preset frequency signal at the current volume, i.e., is unable to hear the preset frequency signal at the current volume.
[0086] According to actual needs, the first hearing level feedback and the second hearing level feedback can be, for example, gesture action signals, or voice signals, or information signals input by the user, etc. The embodiments of the present disclosure are not limited by the specific feedback signal types of the first and second hearing level feedback.
[0087] It should be understood that the first hearing level feedback and the second hearing level feedback are only intended to distinguish two different hearing level feedback situations, and are not intended to limit them.
[0088] The first and second hearing level feedback may be, for example, feedback signals of the same type, or feedback signals of different types, but the embodiments of the present disclosure are not limited thereto.
[0089] It should be understood that when obtaining the second hearing level feedback from the user, the current volume of the preset audio signal is recorded, and the current volume is determined as the maximum inaudible volume of the preset frequency point. This means that when the second hearing level feedback is obtained, for example, it is characterized that the user cannot hear the preset frequency signal at the current volume. At this time, for example, the volume can be recorded, and the volume is the maximum inaudible volume of the user at the frequency point.
[0090] Based on the above, in the present disclosure, by setting up that when the first hearing level feedback is obtained from the user, the current volume is not recorded; when the second hearing level feedback is obtained from the user, the current volume is recorded, and the current volume is determined as the maximum inaudible volume of the preset frequency point, so that corresponding processing can be flexibly performed based on different hearing level feedbacks, and the second hearing level feedback associated with the user's poor hearing can be accurately captured and the corresponding maximum inaudible volume can be obtained, thereby effectively and accurately determining the maximum inaudible volume at the frequency point.
[0091] In some embodiments, the hearing level feedback is gesture feedback, and the Bluetooth headset further includes a human-computer interaction component, wherein obtaining the hearing level feedback from the user includes: obtaining gesture feedback from the user via the human-computer interaction component.
[0092] It should be understood that the gesture feedback refers to a feedback signal associated with the user's gesture. For example, different gestures of the user may represent different hearing level feedback.
[0093] It should be understood that the human-computer interaction component refers to a component for user interaction. The human-computer interaction component can be, for example, a mobile terminal that communicates with a Bluetooth headset (which interacts with the user via a display screen and receives input from the user), or it can be a smart Bluetooth headset cabin for the Bluetooth headset. The Bluetooth headset cabin can, for example, accommodate the headset component of the Bluetooth headset and charge the headset component, and the surface of the smart Bluetooth headset cabin can also have a display screen, which can, for example, receive input from the user (such as gestures) via the display screen.
[0094] However, it should be understood that the above are only exemplary human-computer interaction components, and the embodiments of the present disclosure are not limited thereto.
[0095] It should be understood that the human-computer interaction component can be, for example, integrated with the Bluetooth headset (for example, provided in the smart Bluetooth headset compartment of the Bluetooth headset), or the human-computer interaction component can be provided separately from the Bluetooth headset and communicate with each other in the usage scenario. For example, the human-computer interaction component can be the screen of the mobile terminal connected to the Bluetooth headset, which, after establishing a connection with the Bluetooth headset, is reused as the human-computer interaction component of the Bluetooth headset. The embodiments of the present disclosure are not limited to this.
[0096] For example, the human-computer interaction component can be a display screen on a Bluetooth headset cabin, which can display the currently ongoing monaural hearing loss test, such as the headset component currently being tested (which corresponds to the corresponding monaural ear), and the frequency being tested. It can be set with a human-computer interaction area, in which the user's gestures are collected. For example, the first hearing level feedback can be set to the user continuously touching the human-computer interaction area, and the second hearing level feedback can be set to the user stopping touching the human-computer interaction area (that is, the user's finger is away from the human-computer interaction area, for example, no longer touching the screen). At this time, for example, in the process of detecting the hearing level of the ear at a certain preset frequency point, the preset audio signal corresponding to the preset frequency point can be played through the headphone component (the volume of the preset audio signal decreases from a preset maximum volume to a preset minimum volume according to a preset rule), and the user gesture movement in the human-computer interaction area is collected through the display screen. When the user continues to touch the human-computer interaction area (for example, the user keeps pressing the human-computer interaction area of the screen), it can be determined that the user has a good hearing level for the preset frequency signal at the current volume, and the current volume is not recorded at this time; when the user's finger leaves the screen and no longer touches the human-computer interaction area, it indicates that the user has a poor hearing level for the preset frequency signal at the current volume, that is, cannot hear the preset frequency signal at the current volume. At this time, for example, the current volume can be recorded, and the current volume can be determined as the maximum inaudible volume of the preset frequency point.
[0097] Based on the above, by setting the Bluetooth headset to include a human-computer interaction component, during the process of conducting a single-ear hearing loss test, the gesture action feedback from the user (which serves as hearing level feedback) can be reliably and accurately obtained through the human-computer interaction component, and the user's current hearing level can be determined through the gesture action feedback. This effectively improves the user's human-computer interaction experience during the test while accurately and reliably obtaining the user's hearing level and determining the maximum inaudible volume.
[0098] In some embodiments, in the aforementioned step S202 , the determination of the amount of hearing loss of the ear at each preset frequency point based on the maximum inaudible volume of the ear at each preset frequency point may be described in more detail.
[0099] For example, the maximum inaudible volume at the preset frequency point can be directly determined as the amount of hearing loss at the preset frequency point. For example, if the maximum inaudible volume at the user's left ear is 30 dB, 30 dB can be directly determined as the amount of hearing loss at the user's left ear. Alternatively, the maximum inaudible volume can be further processed, for example, using a preset algorithm or function to determine the amount of hearing loss.
[0100] It should be understood that the embodiments of the present disclosure are not limited by the specific method for determining the amount of hearing loss.
[0101] Based on the above, by determining the amount of hearing loss of the ear at each preset frequency based on the maximum inaudible volume of the ear at each preset frequency, the amount of hearing loss of the user can be accurately and reliably determined based on the maximum inaudible volume, which is conducive to subsequent corresponding compensation.
[0102] In some embodiments, the process S103 of performing compensation processing on the original audio signal of the Bluetooth headset at the current moment based on the monaural hearing loss curve corresponding to each ear of the user to generate a compensated audio signal can be described in more detail. Figure 4 An exemplary flow chart of the process S103 of generating a compensated audio signal according to an embodiment of the present disclosure is shown.
[0103] Reference Figure 4 In step S1031, for each earphone component of the Bluetooth headset: determining a monaural hearing loss curve of a corresponding ear of a user corresponding to the earphone component.
[0104] For example, the monaural hearing loss curve corresponding to the ear may be determined based on the ear (eg, the left ear or the right ear) of the user corresponding to the earphone component.
[0105] It should be understood that the monaural hearing loss curve may be stored in a memory built into the earphone component after being generated, and may be retrieved from the memory of the earphone component when compensation is required.
[0106] In step S1032, for each earphone component of the Bluetooth earphone, the original audio signal of the earphone component at the current moment and the preset threshold volume corresponding to the earphone component are obtained.
[0107] The preset threshold volume corresponding to the earphone component refers to the maximum volume value of the audio signal set by the earphone component. This preset threshold volume can be pre-set by the Bluetooth headset or manually set by the user. This preset threshold volume is intended to define the upper limit of the audio volume within the normal range to prevent excessive volume from damaging the user's hearing.
[0108] It should be understood that the above steps S1031 and S1032 can be executed sequentially, in reverse order, or in parallel. The embodiments of the present disclosure are not limited by the specific execution order of the steps S1031 and S1032.
[0109] Thereafter, in step S1033 , compensation processing is performed on the original audio signal based on the monaural hearing loss curve and the preset threshold volume to generate a compensated audio signal.
[0110] The compensation processing refers to compensating the original audio signal (especially volume compensation) to effectively make up for the situation where the user cannot hear the audio signal content below the maximum audible volume in each preset frequency point due to hearing loss.
[0111] For example, the compensation process may include: determining audio compensation parameters based on the monaural hearing loss curve, the volume of the original audio signal, and a preset threshold volume; and performing audio compensation processing on the original audio signal based on the audio compensation parameters to generate a compensated audio signal, wherein the volume of the compensated audio signal is less than the preset threshold volume. However, it should be understood that the embodiments of the present disclosure are not limited to this.
[0112] Based on the above, in the present application, when compensating the original audio signal of the Bluetooth headset at the current moment to generate a compensated audio signal, the monaural hearing loss curve of the user corresponding to each earphone component of the Bluetooth headset is determined; the volume of the original audio signal of the earphone component at the current moment and the preset threshold volume corresponding to the earphone component are obtained; and the original audio signal is compensated based on the monaural hearing loss curve and the preset threshold volume to generate a compensated audio signal. In this way, the compensation process comprehensively considers the monaural hearing loss curve of the current user and the audio upper limit volume (preset threshold volume) within the normal range, thereby flexibly configuring the compensation parameters. On the one hand, good audio volume compensation of the original audio signal at the corresponding frequency point is achieved through the loss curve, and on the other hand, the audio upper limit volume is taken into account to avoid excessive volume after compensation, which may cause damage to the user's hearing, thereby taking into account both audio signal compensation and user hearing protection.
[0113] In some embodiments, continue to refer to Figure 4 The step S1033 of performing compensation processing on the original audio signal based on the monaural hearing loss curve and the preset threshold volume to generate a compensated audio signal can be described in more detail, for example.
[0114] Reference Figure 4 First, in step S1033-1, the frequency point corresponding to the original audio signal is determined, and the hearing loss amount corresponding to the frequency point is determined on the monaural hearing loss curve.
[0115] For example, based on detecting the frequency of the original audio signal, the frequency point corresponding to the original audio signal can be determined, and the hearing loss amount corresponding to the frequency point can be determined on the monaural hearing curve.
[0116] Thereafter, in step S1033 - 2 , audio compensation parameters are determined based on the amount of hearing loss, the volume of the original audio signal, and a preset threshold volume.
[0117] The volume of the original audio signal refers to the volume of the original audio signal that the earphone component is intended to transmit at the current moment. For example, in a call scenario, it represents the volume of the original call audio signal transmitted by the earphone at the current moment.
[0118] It should be understood that the audio compensation parameters refer to parameters used to compensate the original audio signal, and may be, for example, key configuration parameters of an equalizer in the earphone component of a Bluetooth headset, such as a gain parameter corresponding to a frequency point. It should be understood that the embodiments of the present disclosure are not limited by the specific composition and type of the audio compensation parameters.
[0119] For example, the amount of hearing loss, the volume of the original audio signal, and the preset threshold volume can be processed based on a preset algorithm or a pre-trained neural network to determine the audio compensation parameters; or the correspondence between the combination of each amount of hearing loss, the volume of the original audio signal, and the preset threshold volume and the audio compensation parameters can be pre-set, and the expected corresponding audio compensation parameters can be determined based on the current amount of hearing loss, the volume of the original audio signal, and the preset threshold volume.
[0120] It should be understood that the embodiments of the present disclosure are not limited by the specific manner of determining the audio compensation parameters.
[0121] Thereafter, in step S1033 - 3 , audio compensation processing is performed on the original audio signal based on the audio compensation parameter to generate a compensated audio signal, wherein the volume of the compensated audio signal is less than the preset threshold volume.
[0122] It should be understood that, for example, an equalizer may be configured based on the audio compensation parameters, and compensation processing may be performed on the original audio signal via the equalizer to obtain a compensated audio signal.
[0123] It should be understood that in the present application, by setting up in the process of generating the compensated audio signal, first determine the frequency point corresponding to the original audio signal, and determine the hearing loss amount corresponding to the frequency point on the monaural hearing loss curve; then determine the audio compensation parameters based on the hearing loss amount, the volume of the original audio signal and the preset threshold volume; and perform audio compensation processing on the original audio signal based on the audio compensation parameters to generate a compensated audio signal; and make the volume of the compensated audio signal less than the preset threshold volume, so that the compensation method in the present application can simply and conveniently realize the compensation of the original audio data, and by making the generated compensated audio signal less than the audio upper limit volume, avoid the volume being too loud after compensation, which may cause damage to the user's hearing, and take into account both audio signal compensation and user hearing protection.
[0124] In some embodiments, the original audio signal at the current moment is an original call audio signal at the current moment.
[0125] For example, the application scenario of the Bluetooth headset is a call scenario, and the Bluetooth headset is in a call mode (at this time the Bluetooth headset transmits a call audio signal to the user), and the original audio signal at this time is the original call audio signal at the current moment (the call audio signal has not undergone audio compensation processing).
[0126] Based on the above, by specially setting up audio compensation processing for the original call audio signal in the call scenario, it is possible to achieve good audio playback of Bluetooth headsets, especially good call audio playback of Bluetooth headsets. The audio compensation method for Bluetooth headsets can be used based on the hearing loss of different people to perform good audio personalized compensation, thereby improving the user's auditory experience, especially allowing users to have a good call experience in personal calls.
[0127] In some embodiments, before the aforementioned step S201 of detecting the hearing level of each ear of the user at multiple preset frequencies to obtain the maximum inaudible volume of the ear at each preset frequency, the method further includes: performing a hearing loss test preprocessing operation.
[0128] It should be understood that the hearing loss test preprocessing operation refers to the pre-processing process before performing the monaural hearing loss test, which is intended to improve the reliability and accuracy of the hearing loss test. This preprocessing operation may include, for example, user information collection, noise detection, and wearing detection. The embodiments of the present disclosure are not limited to this.
[0129] Based on the above, in this application, by setting up a hearing loss preprocessing operation before executing the hearing loss test, the reliability and accuracy of the hearing loss test and the obtained monaural hearing loss curve can be better improved.
[0130] In some embodiments, the hearing loss test preprocessing operation includes: receiving user's personal information; wherein the personal information includes at least one of user's age, user's gender, and user's hearing level information.
[0131] It should be understood that, for example, the user's personal information can be received via the aforementioned human-computer interaction interface. For example, the human-computer interaction interface can display a user information input window or options, and the user can fill in or select corresponding content according to his or her own situation.
[0132] The user hearing level information refers to the overall hearing level evaluation of the user, which may include, for example, options such as excellent, good, and poor. However, it should be understood that the above is only an example of user hearing level information, and the embodiments of the present disclosure are not limited thereto.
[0133] Thereafter, based on the personal information, a preset frequency point in the hearing loss test is determined.
[0134] For example, based on the personal information, the preset frequency corresponding to the user can be determined in the alternative frequency library. For example, the preset frequency range and frequency distribution of the user can be determined based on the personal information to obtain the preset frequency. Specifically, for example, for users who are younger and have good hearing levels, 9 preset frequencies of 250Hz, 500Hz, 1000Hz, 3000Hz, 4000Hz, 5000Hz, 6000Hz, 7000Hz, and 8000Hz can be selected; and for users who are older and have poor hearing levels, for example, high-frequency subdivisions such as 6500Hz, 7500Hz, and 8500Hz can be further added on the basis of the above-mentioned preset frequencies (taking into account that the hearing level for high-frequency frequencies decreases with age). In addition, for example, for male or female users, the preset frequency can be determined based on the corresponding male hearing vulnerability frequency range and female hearing vulnerability frequency range.
[0135] Based on the above, in this application, by setting up to receive the user's personal information before conducting a hearing loss test, and determining the preset frequency points in the hearing loss test based on the personal information, it is possible to personalize the selection of preset frequency points based on the user's personal characteristics, thereby better adapting to the needs and situations of different users.
[0136] In some embodiments, the hearing loss test preprocessing operation includes at least one of noise detection and wearing detection.
[0137] The noise detection refers to detecting the noise situation of the current Bluetooth headset accessories. For example, the surrounding environmental noise can be detected through the earphone component of the Bluetooth headset. When the volume of the surrounding environmental noise is less than the preset environmental noise threshold, it is determined that the noise detection has passed. When the volume of the surrounding environmental noise is greater than or equal to the preset environmental noise threshold, it is determined that the noise detection has failed.
[0138] It should be understood that the preset environmental noise threshold may be, for example, 50 dB, or 40 dB, and the embodiments of the present disclosure are not limited by the specific numerical value of the preset environmental noise threshold.
[0139] Wear detection refers to detecting whether the Bluetooth headset is properly worn by the user. This wear detection can be performed, for example, by playing sample audio to the user through the headset component, collecting the audio through the headset's built-in microphone to obtain a captured signal, and then determining whether the headset is properly worn by the user based on the characteristics of the captured signal.
[0140] Based on the above, noise detection can ensure that the external environment is in a less noisy state when conducting hearing loss testing, which is conducive to reducing the interference of external environmental noise and improving detection accuracy; wearing detection ensures that the Bluetooth headset is in a good wearing state when conducting hearing loss testing, thereby avoiding incorrect hearing loss judgment caused by incorrect wearing of the headset.
[0141] According to another aspect of the present disclosure, a Bluetooth headset is provided. Figure 5 FIG. 4 is a schematic diagram of a Bluetooth headset 300 according to an embodiment of the present disclosure.
[0142] Reference Figure 5 The Bluetooth headset includes a pair of earphone components 310 and 320, which correspond to the user's ears respectively, and each earphone component includes a processor and a memory.
[0143] And wherein, for each earphone component: the memory stores a monaural hearing loss curve of the corresponding ear of the user corresponding to the earphone component, wherein the monaural hearing loss curve of the corresponding ear of the user is generated based on a monaural hearing loss test performed on the corresponding ear of the user.
[0144] It should be understood that the monaural hearing loss curve refers to a curve that characterizes the degree of hearing loss of a single ear (e.g., the left ear or the right ear) when performing listening activities. It may, for example, include hearing loss data of the user at multiple preset frequency points. However, it should be understood that the embodiments of the present disclosure are not limited to this.
[0145] It should be understood that the monaural hearing loss test refers to testing the hearing loss degree of each ear of the user separately to obtain a monaural hearing loss curve.
[0146] The processor is configured to: obtain the monaural hearing loss curve from the processor; obtain the original audio signal of the earphone component at the current moment; and perform compensation processing on the original audio signal at the current moment based on the monaural hearing loss curve to generate a compensated audio signal.
[0147] It should be understood that the original audio signal of the earphone component at the current moment refers to the original audio signal that the earphone component is intended to transmit to the user at the current moment. Specifically, in a Bluetooth call scenario, the audio signal can be, for example, the original call signal; in an audio playback scenario, the audio signal can be, for example, the original audio signal. It should be understood that the embodiments of the present disclosure are not limited by the specific signal type of the original audio signal.
[0148] The original audio signal, used to distinguish it from the compensated audio signal, refers to an audio signal that has not undergone the audio compensation process in this application. It should be understood that the embodiments of the present disclosure are not limited by the signal type or signal content of the original audio signal.
[0149] The compensation processing refers to a process of compensating the original audio signal (eg, compensating the volume value of the audio signal) and / or adjusting the original audio signal (eg, reducing the volume of the audio signal that obviously exceeds the maximum volume range).
[0150] Based on the above, in this application, through the Bluetooth headset and its corresponding configuration, it is possible to use a simple and convenient method to compensate for the hearing loss of different people based on the audio compensation method for Bluetooth headsets, and perform good audio personalized compensation for the audio signal according to the monaural hearing loss curve, thereby improving the user's auditory experience, especially allowing the user to have a good call experience in personal calls.
