Hearing Aids are electronic, battery-operated devices that amplify and change sounds to allow for improved hearing. Hearing Aids do not affect your hearing loss, rather they amplify the sounds so those with a hearing loss can hear better. Hearing aids convert sound waves that they receive through a microphone to electrical signals. Hearing Aids include an amplifier that increases the loudness of signals which are sent to the ear through the hearing aid's speaker.

Hearing Aids are usually distinguished by where they are worn: ITE (in the ear), ITC (in the canal), CIC (completely in the canal), BTE (behind the ear), or on the body.
