cochlear implant

 
a device consisting of a microphone, signal processor, external transmitter, and implanted receiver; the receiver is surgically implanted under the skin near the mastoid process above and behind the ear. It is an alternative to total deafness, although it does not actually restore hearing. Deaf persons using the implant do not hear sounds in the same way hearing persons do, but they can be taught to interpret sounds transmitted by the device.

cochlear implant

A device designed to stimulate the acoustic nerve so as to produce some form of hearing in people wholly deaf from inner ear disease. Although there have been great advances in multichannel implants, the results still cannot be said to compare with natural hearing. But cochlear implants can make a substantial difference to children born deaf or becoming totally deaf before 3 years of age, so long as the implant is inserted before the age of five. Most of the children who receive such implants are able to develop intelligible speech.
