Hearing aids help by making most
sounds clearer for the brain. Sounds that you can’t hear as well are made louder.
Hearing aids also filter sound to reduce some background noise. And they soften some
sounds that may be too loud. As a result, signals traveling to the brain are easier
The microphone picks up sound and carries it into the hearing aid. The amplifier makes
the sound louder and clearer. The receiver sends this stronger sound into the ear
canal. The stronger sound travels the rest of the way into the ear to the brain.
