The cochlear implant consists of an internal and an external component
The internal component (implanted through surgery) is in turn made up of a very thin metal wire with a variable number of electrodes which is inserted into the patient’s cochlea, a body and a magnet which are positioned under the skin and a magnet , positioned above and behind the auricle.
The external component (similar to a conventional hearing aid) is represented by a language processor and a second magnet, connected to it via a cable.
The speech processor is a sophisticated device that receives sound information from the environment, digitizes it, processes it according to the instructions with which it was programmed and transmits it to the internal component through a radio frequency communication system.
