How it works

1. Sound is picked up by a microphone
2. Sound is sent from the microphone to the speech processor

3. The speech processor analyses and digitises the sound into coded signals
4. Coded signals are sent to the transmitter

5. The transmitter sends the code across the skin to the internal implant
6. The internal implant converts the code to the electric signals
7. The signals are sent to the electrodes to stimulate the remaining nerve fibres
8. The signals are recognised as sounds by the brain producing a hearing sensation


Cochlear implants provide a heightened sense of sound for adults and children with profound hearing loss. They are designed for people whose hearing does not improve with surgical correction or with use of a hearing aid. Cochlear implants will not restore or create normal hearing.

A Cochlear implant is a proven medical option designed to help your child with hearing loss communicate more easily and interact more comfortably with others. It's an alternative to the traditional attempts to improve hearing ability, such as powerful hearing aids, which in some cases provide little or no assistance.
