Embodiment 1
[0074] Grandpa Liu is nearly seventy years old. It was diagnosed by the hospital that the auditory nerve of the brain is not damaged, but the eardrum is damaged. It does not respond to 130Hz-300Hz frequency sound, so it cannot be transmitted to the brain nerve through the vibration feedback of the eardrum. Invented and developed bone conduction hearing aids. Because when Grandpa Liu is not wearing a hearing aid, he can only hear the audio signal transmitted by the vibration of the eardrum. When Grandpa Liu's auditory senses are reflected, he can hear a section, but suddenly there is a section or the audio reception stops, and because ordinary people speak The frequency will not fluctuate greatly, so there may be a large segment missing. Then, Grandpa Liu only needs to press the switch button on the hearing aid, and then the hearing aid switches to the Y1-78 curve selection, matches and filters the audio signal output from the outside, and outputs a section of audio with the st...

The invention provides an autonomous correction hearing aid system and a method based on multi-band gain compensation. Firstly, external sound is picked up through the sound pickup module; after a switching command of a user is received, the main control module performs filtering conversion on an external audio signal according to the switching command, divides the external audio signal into a non-target frequency band and a target frequency band according to target threshold section data, and outputs the target frequency band in a bone conduction mode for the user to receive; in the process,the user does not need to perform excessive complex operations; moreover, the main control module records and marks the target threshold segment data and the amplitude magnification times extracted atthe last time. Namely, activation and extraction do not need to be carried out again in the later use process, so that to a certain extent, the operation of the whole system only needs to be simply called and controlled to select the working state most suitable for the user.
Description
technical field [0001] The invention relates to the technical field of bone conduction hearing aids, in particular to an autonomously correcting hearing aid system and method based on multi-band gain compensation. Background technique [0002] "Sounds come from what you hear, and colors come from seeing what you see." This is a wonderful world. But for people with hearing impairment, the world of sound is blurred, and what's more, sounds in a certain frequency range cannot be heard, which is equivalent to missing a corner of the world. [0003] However, with the development of technology, many bone conduction hearing aids have appeared on the market. Although hearing aids can compensate for hearing loss, the first bone conduction hearing aids on the market are usually expensive and have a poor appearance. After market adjustments, bone conduction hearing aids have also evolved to a stage with relatively complete functions. For example, you can seek professional adjustments ...
