Problems solved by technology
The current bone conduction hearing aid usually has a fixed amplitude of the sound amplification signal, and for different hearing-impaired patients, each person has a different degree of hearing impairment, which leads to the fact that the sound with a fixed amplitude output by the bone conduction hearing aid cannot be compared with different hearing-impaired patients. Matching for the hearing impaired

The invention provides a bone conduction hearing aid output volume autonomous adjustment method and device. The method comprises the following steps: acquiring external sound waves received by the bone conduction hearing aid, and constructing a sound linear time-varying controlled system according to the external sound waves; establishing a system performance evaluation function according to the sound state and the control quantity in the sound linear time-varying controlled system; constructing a conditional differential equation oriented to a sound linear time-varying controlled system and a system performance evaluation function within a duration; and determining an analytic solution of the control quantity according to the solution of the conditional differential equation, controlling a sound linear time-varying controlled system by adopting the analytic solution of the control quantity, and outputting a sound state with an expected amplitude to the eardrum of the hearing-impaired patient. The sound amplification range of the bone conduction hearing aid can be adjusted according to the hearing injury degrees of different hearing-impaired patients, the hearing amplification requirements of the different hearing-impaired patients are met autonomously, manual debugging of the hearing amplification range is not needed, and the use generalization of the bone conduction hearing aid is enhanced.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of bone conduction hearing aid control, and in particular, to a method and device for autonomously adjusting the output volume of a bone conduction hearing aid. Background technique [0002] Bone conduction hearing aids transmit sound waves through the human skull, auditory nerve and auditory center by converting sound into mechanical vibrations of different frequencies. Bone conduction hearing aids use bone conduction technology to receive speech, and sound waves are directly transmitted to the auditory nerve through the bone, so both ears can be opened. The current bone conduction hearing aids usually have a fixed amplitude of the sound amplification signal, and for different hearing impaired patients, the degree of hearing impairment of each person is different, which leads to the output of bone conduction hearing aids. Hearing impaired people are matched. Therefore, developing a m...
