How hearing aids work
All hearing aids use the same basic parts. Hearing aids carry sounds from outside your ear into your ear to make sounds louder.
Most hearing aids are digital. All run on batteries. Some use batteries that you can recharge.
Small microphones collect sounds around you. A computer chip changes the sounds into digital code. Hearing aids adjust the sound based on your hearing loss, what you need to hear, and how loud the sounds around you are.
Hearing aids turn up the signals and change them back into sound waves. The sound waves go into your ears through speakers, also called receivers.
