A '''cochlear implant''' is an [[electronic device]] used by some people who have a [[hearing loss]]. It artificially stimulates the [[auditory nerve]] to create the sensation of sound. This can be sufficient for the implantee to "hear" well enough for them to learn to listen and speak in the hearing world.  Typically, only those with a severe or profound hearing loss will use cochlear implants as those with less severe losses are able to obtain a sufficient level of hearing using traditional [[hearing aid]]s.

==How cochlear implants work==

An implant consists of four main components.  A sensitive [[microphone]], which sits behind the ear, collects sound and converts it to an electronic signal.  This signal is received by the speech processor - a small computer that sits behind the ear or, in older models, in a body-worn pouch.  The speech processor converts the original signal to a number of separate signals, each of which corresponds to a different band of [[frequency|frequencies]].  These signals are sent to a transmitter on the head and by the transmitter across the skin to the implanted electrodes in the [[cochlea]].  Each signal from the speech processor is sent to a different electrode, and each electrode is placed at a different point in the cochlea.  The brain interprets the signal at each different point in the cochlea as being of a different frequency, thus replicating the original sound picked up by the microphone.
