Description

Technical Field

[0001] This invention relates to the field of hearing aids, specifically to a method for automatic mode switching of hearing aids in various environments. Background Technology

[0002] Hearing aids are a common hearing-assistance tool that amplifies sounds that were previously inaudible. Through the residual hearing of the person with hearing loss, the sound is transmitted to the auditory center of the brain, allowing the person with hearing loss to hear sounds and communicate with others normally.

[0003] Although hearing aids currently have multiple preset modes that allow wearers to switch automatically in different environments, frequent mode switching may cause the internal software of the hearing aid to become less stable, resulting in stuttering or response delays, which may affect the wearer's normal use. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a method for automatic mode switching of hearing aids for various environments.

[0005] The technical solution adopted by this invention to solve its technical problem is: a method for automatic mode switching of a hearing aid for multiple environments, comprising the following steps: Step 1: Command Settings (1) Mode settings: Multiple modes are preset in the hearing aid. Each mode is optimized for a specific environment to ensure that the wearer can get the best experience in different environments. All modes are arranged in order and correspond to the manual switching button on the hearing aid. Download a dedicated adjustment software on a commonly used smart terminal. (2) Set the switching command, record the sound syllables when the wearer reads the mode name, process them, and set them as a comparison template as the command to switch to this mode, so that the wearer can control the switching of hearing aid mode by voice. Step 2: Voice Recognition (1) Sound acquisition and analysis: The hearing aid captures the sound of the surrounding environment through the built-in microphone and preprocesses the acquired sound signal, including filtering and noise reduction, in order to improve the signal quality; (2) Sound classification: perform spectrum analysis on the sound, identify the frequency, intensity and other characteristics of the sound, divide the collected sound into ambient noise and the wearer's own voice, and detect whether the wearer issues a command when changing the environment. Step 3: Switch Mode (1) Switching modes: When the recognition software inside the hearing aid recognizes the switching command issued by the wearer, the hearing aid switches to the corresponding mode according to the received command and automatically adjusts the internal parameters. (2) Playing sound: The microphone receives ambient noise and converts it into an electrical signal, which is then amplified by an amplifier and sent to the wearer's ear through a vibrator structure, so that the wearer can hear the ambient sound. (3) Manual switching: When the wearer has difficulty clearly stating the instructions due to special circumstances, they can press the manual switching button on the hearing aid to switch, or connect the hearing aid to the smart terminal and use the debugging software downloaded in the smart terminal to switch the working mode of the hearing aid.

[0006] Specifically, the hearing aid has preset modes including quiet mode, noise mode, music mode, call mode, and sleep mode, and the types of modes can be set according to the wearer's situation.

[0007] Specifically, the hearing aid employs various noise reduction technologies, such as digital signal processing and spectrum compression, to reduce background noise and improve the signal-to-noise ratio, ensuring that the wearer can always hear the desired sound clearly.

[0008] Specifically, the smart terminal is a smartphone or other portable smart device that connects to the hearing aid via Bluetooth, and the hearing aid remains connected during use.

[0009] Specifically, the hearing aid has only one manual switching button. The mode is switched by controlling the number of times the manual switching button is pressed. The hearing aid is also equipped with an indicator light. The number of times the indicator light changes color is the same as the number of modes set and they correspond one-to-one, ensuring that the wearer knows which working mode the hearing aid is in before wearing it.

[0010] Specifically, the hearing aid is equipped with an adaptive directional microphone system that can automatically adjust the microphone sensitivity according to the location of the sound source, effectively collect signals from the direction of the sound source, and reduce noise from other directions.

[0011] Specifically, when the hearing aid switches modes, it will simultaneously send the modified parameters to the smart terminal worn by the wearer, who can view them and adjust the parameters of the current hearing aid mode according to their own situation.

[0012] Specifically, when switching modes, the hearing aid will play the changed voice message to the wearer so that the wearer knows that the hearing aid has switched working modes.

[0013] The beneficial effects of this invention are as follows: By setting an instruction for each mode in the hearing aid, the hearing aid will automatically switch to the corresponding mode only when the wearer speaks the specified instruction. This prevents the hearing aid from frequently switching modes due to changes in the environment, thereby avoiding frequent mode switching that could lead to a decrease in the stability of the hearing aid's internal software.

(3) Manual switching: When the wearer has difficulty clearly stating the instructions due to special circumstances, they can press the manual switching button on the hearing aid to switch, or connect the hearing aid to the smart terminal and use the debugging software downloaded in the smart terminal to switch the working mode of the hearing aid.

[0018] The hearing aid has preset modes including quiet mode, noise mode, music mode, call mode and sleep mode, and the types of modes can be set according to the wearer's situation.

[0019] The hearing aid employs various noise reduction technologies, such as digital signal processing and spectrum compression, to reduce background noise and improve the signal-to-noise ratio, ensuring that the wearer can always hear the desired sound clearly.

[0020] The smart terminal is a smartphone or other portable smart device that connects to the hearing aid via Bluetooth, and the hearing aid is always connected during use.

[0021] The hearing aid has only one manual switching button. The mode is switched by controlling the number of times the manual switching button is pressed. The hearing aid is also equipped with an indicator light. The number of times the indicator light changes color is the same as the number of modes set and they correspond one-to-one, so that the wearer knows which working mode the hearing aid is in before wearing it.

[0022] The hearing aid is equipped with an adaptive directional microphone system that can automatically adjust the microphone sensitivity according to the location of the sound source, effectively collect signals from the direction of the sound source, and reduce noise from other directions.

[0023] When the hearing aid switches modes, it simultaneously sends the modified parameters to the smart terminal worn by the wearer, who can view them and adjust the parameters of the current hearing aid mode according to their own situation.

[0024] The hearing aid plays a voice message indicating the changed mode to the wearer when switching modes, so that the wearer is aware that the hearing aid has switched working modes.

[0025] During operation, the hearing aid is pre-programmed with multiple modes, each optimized for a specific environment to ensure the wearer receives the best experience in various settings. All modes are arranged sequentially, corresponding to the manual switching buttons on the hearing aid. A dedicated tuning software is downloaded to a commonly used smart device, recording the wearer's voice syllables when pronouncing the mode name. This information is then processed and set as a comparison template, serving as the command to switch to that mode. This allows the wearer to control the hearing aid's modes via voice. The hearing aid captures ambient sound through its built-in microphone, preprocesses the acquired sound signals (including filtering and noise reduction) to improve signal quality, and performs spectral analysis to identify the frequency and intensity of the sound. Based on these characteristics, the system categorizes the collected sounds into ambient noise and the wearer's own voice. It detects whether the wearer issues a command when changing their environment. When the internal recognition software of the hearing aid identifies the switching command issued by the wearer, the hearing aid switches to the corresponding mode according to the received command, automatically adjusting its internal parameters. The microphone converts the received ambient noise into an electrical signal, which is then amplified by an amplifier and sent to the wearer's ear through a vibrator structure, allowing the wearer to hear the surrounding sounds. When the wearer has difficulty clearly stating the command due to special circumstances, they can press the manual switching button on the hearing aid to switch modes, or connect the hearing aid to the smart terminal and use the software downloaded on the smart terminal to switch the hearing aid's working mode.
