Unlike a hearing aid, it does not merely amplify sound. Instead, an implant increases the amount of nervous response to sound
Cochlear Implant
A cochlear implant can help people who are completely deaf to "hear" sound. They can hear well enough to understand speech, even over the telephone. A hearing aid cannot help someone who is completely deaf to hear anything.
The external part of a cochlear implant (called a processor) can be removed easily (it has a magnet that adheres to the outer skin and what looks like a hearing aid that sits on the ear). The internal part of a cochlear implant can also be removed -- but would need to be done so surgically.
Cochlear implant. A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. The cochlear implant is often referred to as a bionic ear.

Cochlear implants are used to make hearing possible for those with sensorineural hearing impairment.
Cochlear implants are electronic devices made up of two parts: an implanted component that is inserted during an operation, and external components worn on the head or body like a hearing aid. Cochlear implants provide a sensation of hearing for people who cannot obtain useful benefit from conventional hearing aids; the implant bypasses the damaged hair cells in the inner ear and stimulates the nerve of hearing directly. They are appropriate for both adults and children with severe to profound hearing impairment in both ears.

Doctor Graeme Clark invented the Cochlear implant (bionic ear) at the University of Melbourne.
Electrodes placed inside the cochlear receive the decoded signals. The 22 electrodes allow a range of different pitches to be detected. The electrodes stimulate the hearing receptors.
