Description

Technical Field

[0001] This invention discloses a method for precise audio frequency compensation in hearing aids, belonging to the field of hearing aid technology. Background Technology

[0002] Precise audio compensation is an audio processing technology that aims to improve sound quality and audibility by analyzing and processing audio signals to achieve precise compensation of sound frequencies. This technology is commonly used in hearing aids, audio enhancement devices, and other applications requiring precise sound processing. The principle of precise audio compensation usually involves spectral analysis of audio signals, which compensates for hearing loss or improves sound quality by identifying and enhancing sound signals within a specific frequency range.

[0003] Existing hearing aids amplify the captured sound waves so that wearers can hear sounds that they could not hear or could not hear clearly before. However, hearing aids also capture sound waves that are inaudible to the human ear. If these are amplified directly, the wearer will hear a lot of noise. Some sounds that the wearer can hear will be amplified to a high decibel level, which will damage the wearer's hearing. Such hearing aids cannot amplify the sound according to the wearer's needs. Summary of the Invention

[0004] The technical problem this invention aims to solve is that existing hearing aids cannot amplify sound according to the wearer's needs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for precise sound frequency compensation in a hearing aid includes the following steps: S1. The signal receiving module receives audio sound waves through its microphone, then converts the received audio sound waves into digital signals, and analyzes the digital signals through the signal analysis module to determine whether the fluctuation range of the digital signals is within the range that normal human ears can hear. S2. The digital signals located in the range that can be heard by the human ear are numbered according to the fluctuation range through the proportional amplification module. At the same time, the range of sound waves that the wearer can hear is recorded, and the range of sound waves that the wearer can hear is numbered again. The two sets of numbers correspond to each other. Then, the amplification factor of the sound wave range in the two sets of numbers is calculated, and the digital signals with the same number are amplified proportionally according to the number factor. S3. The digital signals in the inaudible range are eliminated by the signal cancellation module; S4. The digital signal is processed by the signal processing module to eliminate short-frequency signals in the digital signal, and then input into the playback module for playback. The playback module converts the digital signal into an electrical signal, and then the electrical signal is converted into sound waves for playback through the speaker.

[0006] As a preferred embodiment of the present invention, the signal analysis module in step S1 includes a signal frequency analysis module and a signal transmission module. The signal frequency analysis module performs frequency analysis on the looped digital signal to determine whether the sound wave frequency of the digital signal is within the range that the human ear can hear. When the digital signal frequency is within the audible range, the digital signal is input to the proportional amplification module through the signal transmission module. When the digital signal frequency is within the inaudible range, the digital signal is input to the signal cancellation module through the signal transmission module.

[0007] As a preferred technical solution of the present invention, the equal-ratio amplification module in step S2 includes a numbering module and an amplification module. The numbering module numbers the sound wave signals that can be heard by the human ear in ascending order according to a fixed number, and the numbering interval is set in decibels. Then, the sound wave range that the wearer can hear is numbered synchronously. At this time, the signal numbers that can be heard by the human ear correspond to the signal numbers that the wearer can hear in descending order, and the number of the two sets of numbers is the same. The amplification module calculates the amplification factor for each signal number between the wearer's audible signal number and the human ear's audible signal number, and then amplifies the digital signal according to the amplification factor corresponding to each signal number.

[0008] As a preferred technical solution of the present invention, the signal cancellation module in step S3 includes a signal deletion module and a signal recording module. The signal deletion module deletes signals in the audio that are inaudible to the human ear, and the signal recording module records the deleted signals.

[0009] A precise sound frequency compensation system for a hearing aid includes the following modules: Signal receiving module: The signal receiving module receives audio sound waves through its microphone and then converts the received audio sound waves into digital signals; Signal Analysis Module: The signal analysis module analyzes digital signals to determine whether the fluctuation range of the digital signals is within the range that is normally audible to the human ear; Proportional Amplification Module: The digital signal located in the range of human hearing is amplified proportionally to the range of sound waves audible to the wearer. Signal cancellation module: The signal cancellation module cancels digital signals that are inaudible. Signal processing module: The signal processing module processes the digital signal, eliminates short-frequency signals in the digital signal, and then inputs it into the playback module for playback; Playback module: The playback module converts digital signals into electrical signals, and then the electrical signals are converted into sound waves for playback through the speaker.

[0010] The beneficial effects achieved by this invention are as follows: This invention provides a method for precise sound frequency compensation in hearing aids. This method uses a proportional amplification module to number digital signals located in the range audible to the human ear according to their fluctuation range. At the same time, the range of sound waves audible to the wearer is recorded, and the range of sound waves audible to the wearer is numbered again. The two sets of numbers correspond to each other. Then, the amplification factor of the sound wave range in the two sets of numbers is calculated, and digital signals with the same number are amplified proportionally according to the numbering factor, so that the amplified sound meets the wearer's needs.

S2. The digital signals located in the range that can be heard by the human ear are numbered according to the fluctuation range through the proportional amplification module. At the same time, the range of sound waves that the wearer can hear is recorded, and the range of sound waves that the wearer can hear is numbered again. The two sets of numbers correspond to each other. Then, the amplification factor of the sound wave range in the two sets of numbers is calculated, and the digital signals with the same number are amplified proportionally according to the number factor. Proportional amplification refers to amplifying all sounds at the same ratio, regardless of their intensity.
