How does a hearing aid work?

Asked by Topperlearning User | 4th Jun, 2014, 01:23: PM

Expert Answer:

A hearing aid is a battery operated electronic device. It receives sound through a microphone which converts the sound waves to electrical signals. These electrical signals are amplified by an amplifier and sent to speakers of hearing aid. The speaker converts the amplified electrical signal to sound and sends to the ear for clear hearing.
