How Hearing Aids Work

How hearing aids work. Hearing aids use small microphones to collect sounds. They also contain a computer chip that converts the incoming sound, then analyzes it and adjusts it based on your hearing loss. You hear the audio signals through miniature speakers in your ears.

Which hearing aid is right for you depends on the severity of your hearing loss, the environments where you want to hear better, how active you want to be and the technology you’re comfortable with using.
