Description

Technical Field

[0001] This invention discloses an automatic volume adjustment method for air conduction hearing aids, which belongs to the field of hearing testing. Background Technology

[0002] Air conduction hearing aids are hearing aids that conduct sound through the air. They work by collecting sound through a miniature microphone, then processing the collected sound through a digital chip in the hearing aid by noise reduction and amplification, and finally transmitting the processed sound to the auditory nerve through the air conduction path.

[0003] Air conduction hearing aids need to tune and amplify the acquired audio so that the wearer can hear the sound clearly. However, when acquiring audio, hearing aids acquire multiple audio sources simultaneously, including environmental audio and speech audio. Since the frequencies of these multiple audio sources are different, the speech audio is often affected, which in turn affects the clarity of the speech audio played by the hearing aid. Summary of the Invention

[0004] The technical problem this invention aims to solve is that existing hearing aids cannot adjust their configuration according to changes in the wearer's hearing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for automatic volume adjustment in an air conduction hearing aid includes the following steps: S1. First, the receiving module receives ambient audio, and then converts the received audio into a digital signal; S2. The digital signal is denoised by the processing module, and the speech audio part and the environmental audio part in the audio are labeled separately and sorted according to the frequency of the audio. S3. Adjust the volume of voice audio and ambient audio through the adjustment module, analyze the frequency of voice audio, analyze the receiving distance of audio according to the frequency, amplify all audio according to a predetermined magnification, amplify the highest frequency in the voice audio according to the set maximum amplification, and amplify the remaining audio in order of sorting by a reduced amplification. Amplify the ambient audio according to a certain amplification, which is less than the maximum amplification of the voice audio. S4. Play the amplified audio through the playback module.

[0006] As a preferred technical solution of the present invention, in step S2, all voice audios are subjected to distance analysis, and all voice audios are sorted by distance according to the frequency of the audio. Audio distance typically refers to the spatial distance that sound travels from its source to the receiver. This distance affects the intensity and quality of the sound because sound gradually attenuates during propagation, and its intensity decreases with increasing distance.

[0007] As a preferred technical solution of the present invention, in step S3, the part with the highest frequency of the speech audio is the speech closest to the receiving end, and this speech audio is amplified according to a predetermined setting so that this speech audio is clearly transmitted to the hearing aid wearer's ear. The remaining audio audio is sorted by frequency from highest to lowest and amplified in turn, so that these audio audios do not affect the clarity of the most frequent part of the audio. By adjusting the amplification in order of frequency, the distance of the audio can be simulated, making it easier for hearing aid wearers to distinguish the location of the speech.

[0008] As a preferred embodiment of the present invention, the ambient audio amplification factor in step S3 is set to be smaller than the maximum amplification factor of the speech audio. By controlling the amplification factor of the ambient audio, the influence of the ambient audio on the speech audio can be eliminated.

[0009] A comprehensive tinnitus detection system for an air conduction hearing aid includes the following modules: The receiving module receives ambient audio and then converts the received audio into a digital signal. The processing module performs noise reduction on the digital signal, and labels the speech audio and environmental audio parts of the audio separately, and sorts them according to the frequency of the audio. The adjustment module adjusts the volume of voice audio and ambient audio, analyzes the frequency of voice audio, analyzes the receiving distance of audio according to the frequency, and amplifies all audio according to a predetermined magnification. The playback module plays amplified audio.

[0010] The beneficial effects achieved by this invention are as follows: This invention provides an automatic volume adjustment method for an air conduction hearing aid. This method adjusts the volume of speech audio and ambient audio through an adjustment module, analyzes the frequency of the speech audio, analyzes the reception distance of the audio according to the frequency magnitude, amplifies all audio at a predetermined magnification, amplifies the highest frequency in the speech audio at the set maximum amplification, and amplifies the remaining audio in order of order at a reduced amplification. Ambient audio is amplified at a certain amplification, which is less than the maximum amplification of the speech audio, thus greatly reducing the impact on the speech audio and greatly improving the clarity of the speech audio.

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Please see Figure 1-2 This invention provides a technical solution: a method for automatic volume adjustment of an air conduction hearing aid, comprising the following steps: S1. First, the receiving module receives ambient audio, and then converts the received audio into a digital signal; S2. The digital signal is denoised by the processing module, and the speech audio part and the environmental audio part in the audio are labeled separately and sorted according to the frequency of the audio. S3. Adjust the volume of voice audio and ambient audio through the adjustment module, analyze the frequency of voice audio, analyze the receiving distance of audio according to the frequency, amplify all audio according to a predetermined magnification, amplify the highest frequency in the voice audio according to the set maximum amplification, and amplify the remaining audio in order of sorting by a reduced amplification. Amplify the ambient audio according to a certain amplification, which is less than the maximum amplification of the voice audio. S4. Play the amplified audio through the playback module.

[0014] In step S2, all speech audio is subjected to distance analysis, and all speech audio is sorted by distance according to the frequency of the audio. Audio distance typically refers to the spatial distance that sound travels from its source to the receiver. This distance affects the intensity and quality of the sound because sound gradually attenuates during propagation, and its intensity decreases with increasing distance. In practical applications, besides distance, many other factors affect sound intensity, such as the power of the sound source, the level of ambient noise, and individual differences among listeners. Therefore, when using sound intensity to estimate distance, these factors need to be considered comprehensively, and appropriate measurement methods and equipment should be used to obtain accurate results.

[0015] In step S3, the part of the speech audio with the highest frequency is the speech closest to the receiving end. This speech audio is amplified according to the predetermined settings so that the speech audio is clearly transmitted to the hearing aid wearer's ear. The remaining audio frequencies are sorted from highest to lowest and amplified in turn, so that these audio frequencies do not affect the clarity of the most frequent part of the audio. By adjusting the amplification in order of sorting, the distance of the audio can be simulated, making it easier for hearing aid wearers to distinguish the location of the speech. The influence of ambient sound on speech audio is a common phenomenon. Ambient sounds, such as background noise, echoes, and reverberation, all affect the quality of speech audio. These effects may reduce the clarity of speech audio and even change the timbre and intonation of the speech. However, ambient sound is the sound that hearing aids need to transmit. The role of ambient sound in hearing aids is mainly reflected in the following aspects: 1. Improve speech clarity: Ambient sound can help users better understand the speaker's voice, especially in noisy environments, where it can reduce background noise and make the speech clearer; 2. Enhance auditory experience: Ambient sounds can simulate natural sound environments, making users feel more comfortable and increasing their ability to perceive sound. 3. Protect hearing health: The ambient sound volume can be adjusted according to the user's hearing condition to avoid excessive sound amplification that could damage the ears, thereby protecting the user's hearing health.

[0016] In step S3, the ambient audio amplification factor is set to be smaller than the maximum speech audio amplification factor. By controlling the ambient audio amplification factor, the influence of ambient audio on speech audio can be eliminated.

[0017] A comprehensive tinnitus detection system for an air conduction hearing aid includes the following modules: The receiving module receives ambient audio and then converts the received audio into a digital signal. The processing module performs noise reduction on the digital signal, and labels the speech audio and environmental audio parts of the audio separately, and sorts them according to the frequency of the audio. The adjustment module adjusts the volume of voice audio and ambient audio, analyzes the frequency of voice audio, analyzes the receiving distance of audio according to the frequency, and amplifies all audio according to a predetermined magnification. The playback module plays amplified audio.

[0018] Specifically, this method first receives ambient audio through a receiving module, then converts the received audio into a digital signal. A processing module performs noise reduction on the digital signal, and separately labels the speech audio and ambient audio components. The audio is then sorted according to frequency. An adjustment module adjusts the volume of both the speech and ambient audio, analyzes the frequency of the speech audio, determines the reception distance based on frequency, and amplifies all audio at a predetermined magnification. The highest frequency speech audio is amplified at the maximum set magnification, while the remaining audio is amplified at progressively lower magnifications according to their order. Ambient audio is amplified at a certain magnification, which is less than the maximum magnification of the speech audio. Finally, the amplified audio is played back through a playback module.

[0019] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
