Description

A cochlear implant is a small electronic device that helps people hear. It can be used for people who are deaf or very hard of hearing. A cochlear implant is not the same thing as a hearing aid because it is surgically implanted and works in a different way.

There are many different types of cochlear implants -- but they generally consist of several similar parts. One part of the device is surgically implanted into the temporal bone (the bone surrounding the ear). This device consists of a receiver-stimulator, which accepts, decodes, and then transmits an electrical signal to the brain.

The second part of the cochlear implant is an external device. This consists of a microphone/receiver, a speech processor, and an antenna. This portion of the implant receives the sound, converts the sounds into an electrical signal, and transmits it to the internal portion of the cochlear implant.
