A thin cord carries the sound to a miniature computer that filters, analyzes and digitizes the sound into coded signals. The device transmits signals to the cochlear implant under the skin that delivers electrical impulses to the array coiled around the cochlea. Electrodes along the array stimulate the auditory nerve fibers in the cochlea. The resulting electrical sound information is carried along the auditory nerve to the brain for interpretation. The array Inserted approximately an inch into the cochlea, the array consists of 22 electrodes that are individually programmed to decipher sounds.
Every cochlear implant is customized for the user.
