Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of hearing aids, and in particular, to a method, system, device, electronic device, and readable storage medium for binaural adaptive fitting of hearing aids. Background Art

[0002] In the existing hearing aid fitting methods, generally, the hearing aid is connected to a mobile terminal through a Bluetooth module, and operations are performed in a mobile terminal such as an APP to complete the hearing test of a hearing-impaired patient, and then the hearing aid parameters are adjusted to complete the hearing fitting. This hearing fitting mode is relatively complex in operation. As long as a new hearing aid is replaced, the hearing aid needs to be debugged and fitted. For some elderly hearing-impaired patients, frequent fitting of hearing aids without the assistance of others will cause them trouble. In addition, the current hearing fitting method for hearing aids is mainly monaural fitting. For binaural hearing-impaired patients who need to wear hearing aids on both ears, since sound is transmitted through bone conduction, the hearing aids after monaural fitting worn on the left and right ears will affect each other and generate gain redundancy, resulting in noise interference when the hearing aids that are well fitted monaurally are worn on both ears at the same time, and reducing the comfort of binaural hearing-impaired patients using hearing aids. Therefore, developing a method, system, device, electronic device, and readable storage medium for binaural adaptive fitting of hearing aids to effectively overcome the defects in the above-mentioned related technologies has become an urgent technical problem in the industry.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention. In addition, the technical features in each embodiment or individual embodiment provided by the present invention can be combined with each other arbitrarily to form a feasible technical solution. This combination is not restricted by the order of steps and / or the mode of structural composition, but must be based on what can be achieved by those of ordinary skill in the art. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0026] An embodiment of the present invention provides a method for binaural adaptive fitting of hearing aids. Refer to Figure 1, the method includes: emitting multiple sounds with different amplitudes into one ear of a hearing-impaired patient at a certain frequency, recording the first feedback results of the hearing-impaired patient for the sounds with different amplitudes, determining the first sound amplitude at the certain frequency that matches one ear of the hearing-impaired patient according to the first feedback results, and obtaining the first compensation gain of one ear of the hearing-impaired patient at the certain frequency based on the first sound amplitude; emitting multiple sounds with different amplitudes into the other ear of the hearing-impaired patient at the certain frequency, recording the second feedback results of the hearing-impaired patient for the sounds with different amplitudes, determining the second sound amplitude at the certain frequency that matches the other ear of the hearing-impaired patient according to the second feedback results, and obtaining the second compensation gain of the other ear of the hearing-impaired patient at the certain frequency based on the second sound amplitude; determining the first bone conduction factor and the second bone conduction factor, loading the second bone conduction factor to the first adjusted compensation gain and loading it with the second adjusted compensation gain to obtain the first adjusted channel, loading the first bone conduction factor to the second adjusted compensation gain and loading it with the first adjusted compensation gain to obtain the second adjusted channel; using the first adjusted channel and the second adjusted channel to jointly adjust the left and right ear hearing aids, eliminating gain redundancy, and completing the binaural hearing fitting of the hearing aids.

[0027] It should be noted that the certain frequency can be 125HZ, 250HZ, 500HZ, 1000HZ, 2000HZ, 4000HZ or 8000HZ. In actual hearing fitting, multiple frequencies will be selected, and the sounds at each frequency will be fitted according to the hearing fitting method at the certain frequency.

[0028] Based on the content of the above method embodiment, as an optional embodiment, for the binaural adaptive fitting method of hearing aids provided in the embodiments of the present invention, the recording of the first feedback results of the hearing-impaired patient for the sounds with different amplitudes and determining the first sound amplitude at the certain frequency that matches one ear of the hearing-impaired patient according to the first feedback results include: the first feedback results are composed of four combinations of whether the sound is clear and whether the one ear is comfortable, and the sound amplitude corresponding to the combination of clear sound and comfortable one ear among the four combinations is selected as the first sound amplitude.

[0029] Specifically, the four combinations in the first feedback results include: [clear sound, comfortable one ear], [unclear sound, comfortable one ear], [clear sound, uncomfortable one ear], and [unclear sound, uncomfortable one ear]. For example, after the hearing-impaired patient feedbacks that the sound is clear and the one ear is comfortable (such as the hearing-impaired patient presses the corresponding confirmation button), the amplitude of the corresponding sound is recorded as the first sound amplitude at this time, and the first sound amplitude is the sound decibel value that the hearing-impaired patient expects to reach.

[0030] Based on the content of the above method embodiments, as an alternative embodiment, in the hearing aid binaural adaptive fitting method provided in the embodiments of the present invention, the step of obtaining the first compensation gain of one ear of a hearing-impaired patient at the one frequency according to the first sound amplitude includes: subtracting the decibel value of the first sound amplitude from the default amplification decibel value of the hearing aid worn on the one ear and taking the absolute value of the difference to obtain the first compensation gain.

[0031] Based on the content of the above method embodiments, as an alternative embodiment, in the hearing aid binaural adaptive fitting method provided in the embodiments of the present invention, the step of recording the second feedback results of the hearing-impaired patient for sounds with different amplitudes and determining the second sound amplitude at the one frequency that matches the other ear of the hearing-impaired patient according to the second feedback results includes: the second feedback results are composed of four combinations of whether the sound is clear and whether the other ear is comfortable, and selecting the sound amplitude corresponding to the combination of clear sound and comfortable other ear among the four combinations as the second sound amplitude.

[0032] Specifically, the four combinations in the second feedback results include: [sound is clear, the other ear is comfortable], [sound is not clear, the other ear is comfortable], [sound is clear, the other ear is not comfortable], and [sound is not clear, the other ear is not comfortable]. For example, after the hearing-impaired patient gives feedback that the sound is clear and the other ear is comfortable (such as when the hearing-impaired patient presses the corresponding confirmation button), the amplitude of the corresponding sound is recorded at this time as the second sound amplitude, and the second sound amplitude is the sound decibel value that the hearing-impaired patient expects to reach.

[0033] Based on the content of the above method embodiments, as an alternative embodiment, in the hearing aid binaural adaptive fitting method provided in the embodiments of the present invention, the step of obtaining the second compensation gain of the other ear of the hearing-impaired patient at the one frequency according to the second sound amplitude includes: subtracting the decibel value of the second sound amplitude from the default amplification decibel value of the hearing aid worn on the other ear and taking the absolute value of the difference to obtain the second compensation gain.

[0034] Based on the content of the above method embodiments, as an alternative embodiment, in the hearing aid binaural adaptive fitting method provided in the embodiments of the present invention, the step of loading the second bone conduction factor to the first adjusted compensation gain and loading it with the second adjusted compensation gain to obtain the first adjustment channel, and loading the first bone conduction factor to the second adjusted compensation gain and loading it with the first adjusted compensation gain to obtain the second adjustment channel includes:

[0035]

[0036] Wherein, is the second compensation gain, is the second bone conduction factor, is the first adjustment compensation gain, is the second adjustment compensation gain, is the first compensation gain, is the first bone conduction factor; the first adjustment channel and the second adjustment channel are mutually constrained.

[0037] Specifically, the second bone conduction factor is the efficiency when sound is conducted from the one ear (which can be the left ear in another embodiment) to the other ear (which can be the right ear in another embodiment) through the skull (i.e., the retention rate when the sound arrives), and the first bone conduction factor is the efficiency when sound is conducted from the other ear (which can be the right ear in another embodiment) to the one ear (which can be the left ear in another embodiment) through the skull (i.e., the retention rate when the sound arrives). The first adjustment channel is used to adjust the gain in the other ear, and the second adjustment channel is used to adjust the gain in the one ear. After starting the gain adjustment, since the first compensation gain and the second compensation gain have been obtained, and the first bone conduction factor and the second bone conduction factor can be considered as fixed values (the density of the human skull is basically close, so it is default that the first bone conduction factor and the second bone conduction factor of each person are the same. If there are different ones, their first bone conduction factor and the second bone conduction factor can be measured temporarily), then within the neighborhood of the first compensation gain and the second compensation gain (such as the left and right deviation is plus or minus 3 decibels), the first adjustment compensation gain and the second adjustment compensation gain are exhausted until the first adjustment compensation gain and the second adjustment compensation gain that satisfy both the first adjustment channel and the second adjustment channel simultaneously are found (i.e., they are mutually constrained), then the hearing fitting of the binaural hearing aid is completed. Thus, it can be seen that the first compensation gain and the second compensation gain are the expected compensation gains that the binaural hearing aid finally reaches, while the finally determined first adjustment compensation gain and the second adjustment compensation gain are the compensation gains actually set finally in the binaural hearing aid. Thus, through this self-adaptive adjustment method, the binaural hearing aid can autonomously reach the expected compensation gain, thereby eliminating the noise interference caused by gain redundancy.

[0038] The hearing aid binaural adaptive fitting method provided by the embodiment of the present invention can independently perform hearing fitting for different hearing aids, without the need for hearing-impaired patients to manually adjust, nor the need to rely on any external terminal device, enabling hearing-impaired patients to more conveniently perform hearing fitting when replacing new hearing aids, and can eliminate the gain redundancy generated when binaural hearing-impaired patients wear hearing aids on both ears, improving the user experience of binaural hearing-impaired patients.

[0039] The embodiment of the present invention provides a hearing aid binaural adaptive fitting system. Refer to Figure 4 , the system includes: a microphone for collecting external sounds; a digital signal processor for processing digitized audio signals; a speaker for sending the processed sound into the ear; Bluetooth for transmitting external data information to the microcontroller or transmitting the data information of the microcontroller to the outside; a memory for storing the programs that the microcontroller needs to call and the data information that needs to be stored after being processed by the microcontroller; a microcontroller for implementing the hearing aid binaural adaptive fitting method described in any of the foregoing method embodiments.

[0040] The implementation basis of each embodiment of the present invention is achieved through programmed processing by a device with a processor function. Therefore, in engineering practice, the technical solutions and their functions of each embodiment of the present invention can be encapsulated into various modules. Based on this actual situation, on the basis of the above embodiments, the embodiment of the present invention provides a hearing aid binaural adaptive fitting device, and this device is used to execute the hearing aid binaural adaptive fitting method in the above method embodiments. Refer to Figure 2, the device includes: a first main module, configured to emit multiple sounds with different amplitudes to one ear of a hearing-impaired patient at a certain frequency, record the first feedback results of the hearing-impaired patient on the sounds with different amplitudes, determine the first sound amplitude at the certain frequency that matches one ear of the hearing-impaired patient according to the first feedback results, and obtain the first compensation gain of one ear of the hearing-impaired patient at the certain frequency according to the first sound amplitude; a second main module, configured to emit multiple sounds with different amplitudes to the other ear of the hearing-impaired patient at the certain frequency, record the second feedback results of the hearing-impaired patient on the sounds with different amplitudes, determine the second sound amplitude at the certain frequency that matches the other ear of the hearing-impaired patient according to the second feedback results, and obtain the second compensation gain of the other ear of the hearing-impaired patient at the certain frequency according to the second sound amplitude; a third main module, configured to determine a first bone conduction factor and a second bone conduction factor, load the second bone conduction factor to the first adjusted compensation gain and load it together with the second adjusted compensation gain to obtain a first adjusted channel, load the first bone conduction factor to the second adjusted compensation gain and load it together with the first adjusted compensation gain to obtain a second adjusted channel; a fourth main module, configured to jointly adjust the left and right ear hearing aids using the first adjusted channel and the second adjusted channel, eliminate gain redundancy, and complete the binaural hearing fitting of the hearing aids.

[0041] The binaural adaptive fitting device for hearing aids provided by the embodiments of the present invention uses Figure 2 several modules among them, and can independently perform hearing fitting for different hearing aids without the need for the hearing-impaired patient to manually adjust or rely on any external terminal device, enabling the hearing-impaired patient to more conveniently perform hearing fitting when replacing a new hearing aid, and can eliminate the gain redundancy generated when the binaural hearing-impaired patient wears hearing aids on both ears, improving the user experience of the binaural hearing-impaired patient.
