Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of hearing aid fitting parameter conversion, and in particular to a method for converting a plurality of hearing aid fitting parameters under clinical hearing supervision. Background Art
[0002] Hearing aids of different appearance types and product series usually use different hearing aid chips, and different hearing aid chips also correspond to different parameter systems. There is no direct conversion tool between chip parameters. Hearing aids of different appearance types, even if they use the same hearing aid chip and are configured with the same hearing aid parameters, will have certain differences in user hearing perception due to differences in physical properties. Users will have a longer adaptation period when using hearing aids. In daily user phone replacement scenarios, hearing-impaired patients always hope to restore the hearing perception of the hearing aid before the replacement to avoid a too long adaptation process. Therefore, it is necessary to study the conversion method of various hearing aid fitting parameters.
[0003] The prior art, such as the invention patent application announced as CN103491491B, discloses a fully digital hearing aid and a non-traditional hearing aid fitting method, the method comprising: for the typical nonlinear hearing loss diagram type of the target hearing-impaired patient, at least two hearing compensation prescription modes that have been programmed with corresponding hearing aid parameters or processed with nonlinear signals are preset, and the hearing-impaired patient does not need to undergo professional fitting services of traditional digital hearing aids, including but not limited to hearing tests and hearing aid programming and debugging, but directly wears the hearing aid and selects a hearing compensation prescription mode suitable for the hearing loss type and degree of the hearing loss of the hearing-impaired patient. The volume can be adjusted in the hearing compensation prescription mode, and the hearing compensation mode and volume can be selected based on the self-perceived hearing compensation effect. The fully digital hearing aid disclosed by this invention can meet the needs of hearing-impaired patients for self-fitting and has a wide range of applications.
[0004] The prior art, such as the invention patent application CN110719558B, discloses a hearing aid fitting method, apparatus, computer equipment and storage medium, wherein the method includes: obtaining a user's voice response to an excitation sound, wherein the excitation sound is an excitation sound released in the user's ear canal; parsing the voice response through semantic analysis to obtain the response semantics; determining the user's hearing loss based on the excitation sound and the response semantics; determining the hearing compensation corresponding to the user based on the user's hearing loss; and configuring the hearing aid parameters based on the hearing compensation. The excitation sound is released, and then the user's voice response to the excitation sound is obtained, the response semantics of the voice response are parsed, the user's hearing loss is determined based on the excitation sound and the corresponding response semantics, the user's corresponding hearing compensation is determined based on the hearing loss, and the hearing aid corresponding to the user is configured based on the hearing compensation.
[0005] In combination with the above scheme, it is found that in the prior art, the conversion of hearing aid fitting parameters mostly relies on professional fitters to make adjustments based on the parameters of the hearing aid before the conversion, the hearing aid parameter indicators after the conversion and their own experience, as well as the feedback from hearing-impaired patients. On the one hand, the conversion time of the hearing aid fitting parameters is increased. On the other hand, due to the reliance on the fitter's own experience and the feedback from hearing-impaired patients, the accuracy of the hearing aid fitting parameter conversion is reduced, resulting in the hearing aid fitting parameters not being able to meet the needs of hearing-impaired patients after actual conversion. A few of them use hearing compensation and programming technology to adjust the hearing aid fitting parameters, but they still rely on the feedback from hearing-impaired patients in the process, resulting in low efficiency and accuracy in the conversion of the hearing aid fitting parameters, which makes it difficult to meet actual application needs during actual use. Summary of the invention
[0006] The purpose of the present invention is to provide a method for converting a variety of hearing aid fitting parameters under clinical hearing supervision, which solves the problems existing in the background technology.

The input of the network generates a unified latent variable.
[0011] Step 4: Generate converted hearing aid fitting parameters: Based on the unified latent variables, the converted hearing aid features and the unified latent variables are used as The input of the network generates the fitting parameters of the converted hearing aid.
[0012] Step 5: Verify the hearing aid fitting parameter conversion model: Select the test hearing aid from the database characteristics and fitting parameters of the hearing aids The characteristics and fitting parameters of the test hearing aid are processed by the hearing aid fitting parameter conversion model to obtain the test hearing aid Fitting parameters to determine the test hearing aid and testing hearing aids Whether the fitting parameters belong to the same hearing perception fitting parameters, implement fine-tuning training.

The present invention adopts a deep neural network algorithm, which can output the same hearing perception fitting parameters of different hearing aids at one time according to the user characteristics and the characteristics of each hearing aid, so as to facilitate the matching of the fitting parameters of the converted hearing aid during the actual hearing aid fitting parameter conversion process, thereby improving the reusability of the fitting parameter conversion model.

[0031] Embodiment 1:
[0032] Reference Figure 1 As shown, a method for converting multiple hearing aid fitting parameters based on clinical hearing supervision, the method comprising:
[0033] Step 1: Build user features and hearing aid features: Obtain the user's basic information and hearing information, build user features, obtain the information of each hearing aid, and build the features of each hearing aid.
[0034] Step 2: Generate the fitting parameters of each hearing aid at the first level: Based on user characteristics, network, generate latent variables, and input the latent variables and the characteristics of each hearing aid into In the network, the fitting parameters of each hearing aid at the first level are generated.
[0035] Step 3: Generate a unified latent variable: Match the characteristics of the hearing aid to be converted and the characteristics of the hearing aid after conversion from the characteristics of each hearing aid, and select the primary hearing aid fitting parameters corresponding to the characteristics of the hearing aid to be converted and the characteristics of the hearing aid before conversion as the conversion parameters. The input of the network generates a unified latent variable.
[0036] Step 4: Generate converted hearing aid fitting parameters: Based on the unified latent variables, the converted hearing aid features and the unified latent variables are used as The input of the network generates the fitting parameters of the converted hearing aid.
[0037] Step 5: Verify the hearing aid fitting parameter conversion model: Select the test hearing aid from the database characteristics and fitting parameters of the hearing aids The characteristics and fitting parameters of the test hearing aid are processed by the hearing aid fitting parameter conversion model to obtain the test hearing aid Fitting parameters to determine the test hearing aid and testing hearing aids Whether the fitting parameters belong to the same hearing perception fitting parameters, implement fine-tuning training.
[0038] It should be noted that, in a specific embodiment, the database is used to store the type and chip type of each hearing aid, store the hearing sense fitting parameters of each hearing aid, and store The learning rate of the network, The initial value of .
[0039] In a specific embodiment of the present invention, the specific analysis method for constructing user characteristics is: based on the basic information pre-entered by the user, the user's age and gender characteristic data are extracted to obtain the user's basic information.
[0040] Based on the audiogram input by the user, the user's hearing threshold, type of hearing loss and level of hearing loss are extracted to obtain the user's hearing information.
[0041] It should be noted that, in a specific embodiment, the user first inputs basic information, then inputs the user's audiogram, extracts the user's hearing information, and constructs the user's features.
[0042] It should be noted that, in a specific embodiment, the influence of the user's gender on the conversion of hearing aid fitting parameters includes: men usually have more significant hearing loss in the high-frequency part, such as in the range of 2kHz-8kHz, so a higher high-frequency gain needs to be considered when converting hearing aid fitting parameters for men; women usually have obvious hearing loss in the mid-to-high frequency part, such as in the range of 1kHz-4kHz, so a more balanced gain needs to be considered when converting hearing aid fitting parameters for women to avoid excessive amplification of the high frequencies.
[0043] Older users experience high-frequency hearing loss and cannot hear high-frequency sounds clearly. Therefore, when converting hearing aid fitting parameters for older users, the gain of the high-frequency part needs to be considered. Older users have changes in sensitivity to volume. Higher volume or excessive gain may cause discomfort. When converting hearing aid fitting parameters for older users, attention needs to be paid to output limitation and volume control to ensure the comfort of the sound.
[0044] It should be noted that, in a specific embodiment, the user's audiogram is a chart used to record and evaluate a person's hearing, which is obtained through a hearing test. The horizontal axis of the audiogram represents frequency, which is in Hertz and is arranged from low frequency to high frequency. The vertical axis of the audiogram represents loudness, which is in decibels, usually ranging from 0dB to 120dB. The hearing threshold line marks the lowest volume that the tester can hear at each frequency in the audiogram. The lower the hearing threshold, the better the hearing, and the higher the hearing threshold, the more severe the hearing loss.
[0045] Types of hearing loss include conductive hearing loss, sensorineural hearing loss and mixed hearing loss. The conductive hearing loss is usually manifested on the audiogram as a higher hearing threshold in the low frequencies and normal or slight loss in the high frequencies. The sensorineural hearing loss is usually manifested on the audiogram as a higher hearing threshold in both the low and high frequencies and a smoother threshold increase. The mixed hearing loss is usually manifested on the audiogram as a conductive loss in the low frequencies and a sensorineural loss in the high frequencies.
[0046] The level of hearing loss is determined by the range of the hearing threshold. , the hearing loss is judged to be mild, and the hearing threshold is , the hearing loss is judged to be moderate, and the hearing threshold is If the hearing threshold is greater than 80, the hearing loss is considered to be severe; if the hearing threshold is greater than 80, the hearing loss is considered to be profound.
[0047] Combine the user's basic information and hearing information to construct user features, recorded as .
[0048] In a specific embodiment of the present invention, the specific analysis method for constructing the features of each hearing aid is as follows: extracting the type and chip type of each hearing aid from the database, combining the type and chip type of each hearing aid to obtain information of each hearing aid, and constructing the features of each hearing aid based on the information of each hearing aid, which is recorded as ,in , Indicates the number of each hearing aid. Indicates the total number of hearing aids.
[0049] The types of hearing aids include behind-the-ear hearing aids, in-the-ear hearing aids, in-ear hearing aids and bone conduction hearing aids.
[0050] The chip types of the hearing aids include high-end signal processing chips, mid- and low-end signal processing chips, and artificial intelligence chips.
[0051] It should be noted that in a specific embodiment, the high-end signal processing chip has the following characteristics: powerful noise management and background noise filtering functions, which can provide clear voice hearing in complex noise environments, such as Signia Xperience, which has functions such as environmental perception and voice focus, and Phonak Belong supports voice clarity and background noise management.
[0052] The mid- and low-end signal processing chips have the following characteristics: they have certain background noise filtering functions, but the effect is not as good as high-end chips. They can automatically adjust the volume in silent and noisy environments, but they usually cannot provide highly precise adjustments like high-end chips. For example, Oticon Siya provides basic sound amplification and noise filtering functions, and ReSound ENZO3D supports simple noise management and feedback suppression.
[0053] The artificial intelligence chip has the following features: it can sense the wearer's listening environment in real time and automatically adjust audio settings to optimize speech clarity and background noise suppression. Phonak Marvel AI supports intelligent speech recognition and background noise filtering. Oticon More uses deep learning technology to improve sound clarity and can adjust ambient sound perception in real time.
[0054] The present invention uses user characteristics and characteristics of each hearing aid as input data of the fitting parameter conversion model, avoids relying on feedback from hearing-impaired patients during the hearing aid fitting parameter conversion process, and improves the efficiency of hearing aid fitting parameter conversion.
[0055] In a specific embodiment of the present invention, the specific analysis method for generating hidden variables is as follows: based on Network, will The latent space dimension of the network is set to 128.
