4. What are cochlear Implants?
A cochlear implant is an electronic hearing device which is surgically implanted.
The first part of the device is a microphone or transmitter, which is worn externally to pick up sounds in the environment.
The second part is the receiver and electrode system, which is implanted under the skin. Typically, the microphone or transmitter is worn directly behind the ear.

5. Continued
Unlike a hearing aid, a cochlear implant does not amplify sounds.
Cochlear Implants stimulate the auditory nerve, so sounds heard through the implant.
The sounds do NOT sound the same as they are heard through normal hearing.
Voices and environmental noises sound different when heard through a cochlear implant, but those with the device will be able to hear more than if they did not have the implant.

Extensive therapy is usually done after the surgery to help the person with the device learn and relearn the sense of hearing.
