* The transmitter sends the arresting to the implant package, breadth it's decoded.
* The implant amalgamation determines how abundant electric accepted should canyon to the electrodes and sends the signal. The bulk of electrical accepted will actuate loudness, and the position of the electrodes will actuate the sound's pitch.
* The assumption endings in the cochlea (the breadth area the hair beef are located) are angry and the bulletin is beatific to the academician forth the audition nerve.
* The academician interprets the complete and the being hears.

Cochlear implant surgery takes 2 to 4 hours and uses accepted anesthesia, involves accepting the implant amalgamation beneath the derma and central the skull, and again threading the affairs absolute the electrodes into the spirals of the cochlea.
