The inner ear uses the same principle as the microphone captures sound waves or the sound of a loudspeaker, which is the relationship between the moving mechanical part and the air pressure wave. Naturally, when the sound wave is low in sound tone, long in wavelength and large enough, the body can be actually vibrated by the air pressure wave in a 'feeling' manner; the hearing aid is a small loudspeaker, expands the originally inaudible sound, and utilizes the residual hearing of the hearing impaired person to enable the sound to be sent to the brain hearing center so as to feel the sound, thereby bringing great convenience for the hearing impaired person.
