How Hearing Aids Work

Hearing aids are designed to bring sound more effectively into the ear. Most hearing aids consist of at least four parts:

Microphone
Converts external sound waves into electrical energy which is delivered to the amplifier

Amplifier
Increases the strength of the incoming signal as programmed by the professional

Receiver
Converts the amplified electrical energy back into sound waves and delivers them to the ear

Power Source
Provides energy for the various hearing aid functions

Other common parts include:

Telecoil
Picks up electromagnetic fields from the telephone to allow for a clearer signal with less background interference and no feedback. Telecoils are often compatible with many assistive listening systems, such as those found in concert halls or theaters.

Volume control
Allows adjustment of gain.

Toggle button
Allows user to change between programs or settings on a multimemory device.

Remote control
Allows user to change gain or programs, and some allow direct input of audio devices.

Directional microphone
Amplifies sound from the front more than the sides and rear. This feature is very useful in understanding speech in noisy situations.
