Description

Technical Field

[0001] This invention relates to the field of hearing aids, specifically to a sound coordination processing method and apparatus for binaural hearing aids. Background Technology

[0002] One of the most important functions of our ears is localization. For patients with bilateral hearing loss, if they only wear one hearing aid, they may not be able to distinguish left from right when the sound comes from behind. However, if they wear hearing aids in both ears, the intensity of the sound heard by each ear will be different because the sound source is in different locations. This will make the user's direction discrimination more accurate. In addition, the auricle of the human ear has the function of collecting sound and reducing noise. Wearing hearing aids in both ears means that both auricles have the ability to collect sound and reduce noise at the same time, which is of great significance for improving speech discrimination. Chinese Patent Publication No. CN108882136B discloses a binaural hearing aid system with coordinated sound processing, comprising: a first hearing aid and a second hearing aid, each including a microphone and an A / D converter for providing a digital input signal in response to a sound signal received by each microphone in a sound environment; a processor adapted to process the digital input signal according to a predetermined signal processing algorithm to generate a processed output signal; a D / A converter and an output converter for converting the processed sound signal into a sound output signal; and a binaural sound environment detector for performing binaural determination of the sound environment surrounding the user of the binaural hearing aid system based on at least one signal from the first hearing aid and at least one signal from the second hearing aid, thereby providing an output for each of the first and second hearing aids to select the respective hearing aid. The signal processing algorithm of each processor in the binaural hearing aid system enables the hearing aids to perform coordinated sound processing. In the above-mentioned technology, the two hearing aids need to process each sound signal separately, which not only wastes the computing power of the hearing aids, but may also cause output delay and affect the hearing effect. On the other hand, the separate operation of the two hearing aids may make the same sound sound significantly different in timbre. Therefore, there is an urgent need for a sound coordination processing method and device for binaural hearing aids.

Detailed Implementation

[0018] The embodiments of the technical solution of this invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of this invention and are therefore intended to limit the scope of protection of this invention.

[0019] Figure 1 This invention provides a flowchart of a sound coordination processing method for binaural hearing aids. The method is applied to a binaural hearing aid terminal, which can display images, videos, text messages, WeChat messages, and other information. The terminal can be equipped with any terminal device with a display screen, such as a mobile phone, computer, digital broadcasting terminal, messaging device, game console, tablet, medical device, fitness equipment, or personal digital assistant. This embodiment provides a sound coordination processing method for binaural hearing aids, such as... Figure 1 As shown, this method is applied to a binaural hearing aid, which has two audio acquisition devices located on either side of the head. Each audio acquisition device is a microphone, and the two audio acquisition devices are communicatively connected. The communication connection methods include, but are not limited to, Bluetooth, wireless, and wired connections, enabling information sharing. The method includes the following steps S10-S40: In step S10, the two audio acquisition devices synchronously acquire sounds from the surrounding environment and add timestamps to the sounds; In this implementation, the timestamp of the sound can be a time stamp accurate to the millisecond or even microsecond level, so that the timestamp can be used for subsequent processing and analysis of the sound signal.

[0020] In step S20, the sound is analyzed into multiple sound signals with different audio characteristics, wherein the sound signals do not include noise signals; In step S30, adaptive adjustments are made according to the order in which the different sound signals are acquired, and the adaptive adjustment methods include, but are not limited to, changing the output decibel ratio of sound signals with different audio characteristics. In this implementation, by recording the sound signal characteristics acquired by one hearing aid within a certain time domain, and avoiding secondary filtering when the other hearing aid acquires the sound signal with the same characteristics, the computational burden and power consumption of the hearing aid are reduced. This overcomes the binaural sound incoordination that may occur when the two hearing aids process sound signals independently, and ensures that the same sound maintains a basically consistent timbre in the two hearing aids.

[0021] In step S40, the adaptively adjusted acoustic signals are combined into an output signal, which is then amplified and output. In this implementation, different sound signals are superimposed according to their phase, amplitude, and time characteristics, ensuring that the merged signal can accurately reflect the sound environment. The amplification processing device is an amplifier, and the output device can be a loudspeaker.

[0022] In one embodiment, such as Figure 2 As shown, in step S20, the sound is analyzed into multiple sound signals with different audio characteristics, wherein the sound signals do not include noise signals, including the following steps S21-S22: In step S21, the sound is subjected to noise filtering to obtain a noise-reduced sound signal; In this implementation, by using techniques such as spectral subtraction, wavelet transform, and adaptive filtering, noise can be effectively separated and removed from the signal, thereby improving the quality of the sound signal. The resulting sound signal will contain fewer noise components, making it closer to the original, noise-free sound and more suitable for further processing and analysis.

[0023] In step S22, the noise-reduced sound signal is identified according to the acoustic model to obtain all sound signal types; In this implementation, the acoustic model is based on statistical or machine learning techniques to identify and classify the features of sound signals, including but not limited to pitch, frequency, rhythm, and intensity. These types may include human voices, vehicle noise, animal calls, and environmental noise. By identifying the above audio features, a set of sound signal types can be easily obtained.

[0024] In one embodiment, such as Figure 3 As shown, in step S30, adaptive adjustments are made according to the order in which the different sound signals are acquired, and the adaptive adjustments include, but are not limited to, changing the output decibel ratio of sound signals with different audio characteristics, including the following steps S311-S312: In step S311, if the type of sound signal acquired by any of the audio acquisition devices is a second acquisition, then another audio acquisition device is selected to acquire the sound signal of that type for the first time. In step S312, the selected sound signal is adaptively adjusted according to the performance differences between the two audio acquisition devices so that the sound signal can be adapted to the current audio acquisition device. In this implementation, the selected sound signal is a buffered sound signal collected by the hearing aid. The buffered sound signal is processed differently according to the setting program of another hearing aid. Based on the difference in the setting programs of the two hearing aids, the buffered sound signal can be directly reprocessed to adjust the priority of different buffered sound signals, which can correct the difference in hearing loss between the user's two ears. It is worth noting that there is energy consumption between the two hearing aids. Therefore, the reprocessing of the buffered sound signal should also take into account the attenuation of sound intensity so that the user can distinguish the approximate location of the sound.

[0025] In one embodiment, such as Figure 4 As shown, adaptive adjustments are made according to the order in which the different sound signals are acquired, and the adaptive adjustment methods include, but are not limited to, changing the output decibel ratio of sound signals with different audio characteristics, and also include the following steps S321-S323: In step S321, the noise-reduced sound signal is subjected to multi-channel filtering according to the acoustic model to obtain the unselected sound signal; In this implementation, Fourier transform is used to convert the time-domain signal into a frequency-domain signal, and then filtering is performed in the frequency domain. Each frequency domain can be filtered independently. Combined with an acoustic model, signals in specific frequency bands can be extracted or suppressed to obtain multiple single-frequency sound signals. For example, environmental sounds can be decomposed into speech sounds, wind sounds, car noises, horn sounds, etc.

[0026] In step S322, the unselected sound signals are adaptively adjusted according to the performance of the audio acquisition device so that the sound signals can be adapted to the current audio acquisition device. In this implementation, the unselected sound signal is the first sound signal collected by the hearing aid. The first sound signal needs to be differentiated according to the current hearing aid's settings to make the higher priority sound signal easier for the user to hear.

[0027] In step S323, the unselected acoustic signals that have undergone adaptive adjustment are uploaded to the cache for processing, and the cache duration is less than 0.1 seconds; In this implementation, the two hearing aids can share information. The first sound signal collected by one hearing aid can affect how the other hearing aid processes that sound signal. It is worth noting that the two hearing aids are located on opposite sides of the user's head, meaning they are not far apart. Based on this, after one hearing aid collects a sound signal, the other hearing aid will also collect the same sound signal not long afterward. Calculations show that the time difference between the two collections is no more than 0.1 seconds.

[0028] The following are embodiments of the apparatus disclosed herein, which can be used to execute embodiments of the method disclosed herein.

The second adjustment submodule 3012 is used to adaptively adjust the selected sound signal according to the performance difference between the two audio acquisition devices, so that the sound signal can be adapted to the current audio acquisition device.

[0033] In one embodiment, such as Figure 5 As shown, the adjustment module 300 further includes: The filtering module 3021 is used to perform multi-channel filtering on the noise-reduced sound signal according to the acoustic model to obtain the unselected sound signal; The first adjustment submodule 3022 is used to adaptively adjust the unselected sound signal according to the performance of the audio acquisition device, so that the sound signal can be adapted to the current audio acquisition device.
