A cochlear implant is a small hearing device that can help people with profound or severe hearing loss hear again. There are two parts to a cochlear implant: a small piece behind the ear that looks like a hearing aid and a piece that is implanted under the skin surgically. Traditional hearing aids have advanced considerably in the last few years, but they aren’t the right choice for everyone. A small percentage of people with significant hearing loss may need implants. Cochlear implants don’t rely on damaged portions of the ear, they directly stimulate the auditory nerve, which sends signals directly to the brain. This is an entirely different experience of hearing and takes time to become accustomed to. However, for those who have severe hearing loss or are deaf, it can help them function better.
