the-earA Cochlear Implant is a device designed to help severe to profoundly deaf individuals who gain little or no benefit from hearing aids. With their cochlear implant they gain awareness of environmental sounds, most can understand speech without lip-reading and some can use the telephone.

The cochlear implant system converts auditory sound waves into weak electric currents, which are delivered to the immediate vicinity of the auditory nerve in the inner ear or cochlea. The auditory nerve is stimulated by these electric currents and transmits nerve impulses to the brain, where they are understood as acoustic sensations.

Cochlear implants can reconnect those with hearing loss to the world of sound.  They work differently to hearing aids, which amplify sound. A cochlear implant transforms speech and other sounds into electrical energy that is used to stimulate surviving auditory nerve fibres in the inner ear.
