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.
Cochlear implants may help provide hearing in patients who are deaf
because of damage to sensory hair cells in their cochlear. In those
patients, the implants often can enable sufficient hearing for better
understanding of speech.

The quality of sound is different from natural hearing, with less sound
information being received and processed by the brain. However, many
patients are able to hear and understand speech and environmental
sounds.
Newer devices and processing-strategies allow recipients to hear better
in noise, enjoy music, and even use their implant processors while
swimming.

Cochlear implants that operate successfully, including those produced
by all three major manufacturers (Cochlear Corporation, Advanced
Bionics and Med-El), incorporate the same basic design.
Likewise, all cochlear implants incorporate the same basic design to be
capable of the ultimate goal of "detecting" or "demodulating"
intelligence from the human voice when that intelligence is residing
within an electronic signal.

Some cochlear implant designs and intra-cochlear implantations were
made by others (see Cochlear Technology by Adam M. Kissiah, Jr.) prior
to the mid-1970s, and were considered "successful" from a surgical and
medical point of view.
An equal number of proclamations and claims of being "firsts" in
cochlear implantation were also made. Indeed, many important
advances in cochlear implantation were accomplished during the 1960.
