Schematic image of cochlear implantation. The cochlear implant consists of two parts; an audio processor and implant. The audio processor contains microphones, digital signal processor chips, a battery, and an antenna which sends electric stimulation to the implant device which is surgically implanted. The coil of the implant receives the electric signal from the audio processor and sends electric stimulation to the cochlear nerve via the electrode inserted into the scala tympani of the cochlea.
