How do hearing aids work?

Answer

At their most basic, hearing aids are microphones that convert sound into electrical signals. An amplifier increases the strength of the signal, then a receiver converts it back to sound and channels it into the ear canal through a small tube or earmold. A battery is necessary to power the hearing aid and to enable amplification.
