What are cochlear implants used for?

A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard-of-hearing. The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin (see figure).

What are the 4 parts of a cochlear implant?

A coronal view showing the relationship of implant components and inner ear structures. Those components are: 1) speech processor; 2) headpiece; 3) internal implant; and 4) electrode array in the cochlea. The microphone on the speech processor captures sound and the processor converts the sound to a digital signal.

Can a deaf person hear with a cochlear implant?

Cochlear implants allow deaf people to receive and process sounds and speech. However, these devices do not restore normal hearing. They are tools that allow sound and speech to be processed and sent to the brain. A cochlear implant is not right for everyone.
