The surgical procedure is performed to implant the first part of the device in the bone surrounding the temporal bone (ear). The first part is made up of a receiver stimulator that first accepts, then decodes and finally sends an electric signal to the brain.
While the second part is totally an outside device. It is made of an antenna, receiver or microphone and a speech processor. The first step is to receive the sound, followed by converting the sound into an electrical signal and finally sending the sound to the inside part of the device.

The patient needs to know learning and relearning techniques. Hearing through cochlear implant is very different from normal hearing or hearing through hearing aids.

The auditory nerve then sends signals to brain which recognizes them as sounds. Over time, the patients learns to hear and enjoy conversations, environmental sounds and music.
