Cochlear Implant

1. Sound Processor captures sound from the environment processes sound into digital information transmits to the implant over a transmitting antenna, or headpiece, held in place by magnets in both the headpiece and implant 2. Implant converts digital information into electrical signals sends signals down tiny wires to the electrode array in the inner ear delivers electrical signals through tiny contacts, or electrodes, to the hearing nerve the hearing nerve carries the sound information to the brain, where it is heard 3.
