How it works

The Nucleus® System delivers sound in a way that mirrors natural hearing – and is designed to offer people with moderate to profound hearing loss the best in hearing performance.

Unlike hearing aids, which simply amplify sound at the outer ear, a cochlear implant can bypass the damaged part of the ear to directly stimulate the hair cells within the cochlea.

For 30 years Cochlear has been the leading global expert in implantable hearing solutions. The Nucleus System delivers sound in a way that mirrors natural hearing – and is designed to offer people with moderate to profound hearing loss the best in hearing performance.

The latest Nucleus System includes:

A+B. An external sound processor and coil, worn behind the ear.

C. One internal part – the implant, placed just under the skin, behind the ear.

D. A hand held remote assistant (available with the Nucleus 5 System).

How it delivers sound

The sound processor

Captures sound waves and converts them into digital code.

The coil

The digitally coded sound is transferred from the sound processor to the implant by the coil which sits over the implant.

The implant

Converts the digitally coded sound to electrical signals and sends them along the electrode array, positioned in the cochlea (inner ear).

Hearing nerve fibre

The implant's electrodes stimulate the cochlea’s natural hearing nerve fibres, which sends signals to the brain that are interpreted as sound.

The remote assistant

(available with the Nucleus 5 System)
You manage your hearing via the remote assistant or directly from the sound processor. (e.g. change hearing programs or adjust hearing levels)
