Cochlear Implant

What is a cochlear implant?

A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. Unlike hearing aids, which make sounds louder, cochlear implants do the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain.

Who can they help?

Many people have cochlear implants in both ears (bilateral). Listening with two ears can improve your ability to identify the direction of sound and separate the sounds you want to hear from those you don’t.

Cochlear implants can help people who:

• have moderate to profound hearing loss in both ears
• have profound hearing loss in one ear with normal hearing in the other ear
• receive little or no benefit from hearing aids
• score 65% or less on sentence recognition tests done by hearing professional in the ear to be implanted
