How Does A Hearing Aid Work?


A hearing aid is like a very advanced sound system

Sound is picked up by one or more microphones inside the aid, which turns the sound into an electrical code. This code is processed using a microchip and amplifier. This processing means that the sound that comes out in the end is clean and clear. The code then goes into a speaker where it is turned into an acoustic signal again, after which it is sent out into the ear for you to hear it.
