How a Cochlear Implant Works
1. Sound waves enter the system through the microphone (located in the headpiece or the processor). 2. The sound processor converts the sound into a distinctive digital code that has been programmed or "mapped" to maximize sound and speech understanding. 3. Once processed, the electrically coded signal is sent to the headpiece and transmitted through the skin via radio frequency (RF) waves to the implant. 4. The implant receives the signal and delivers it to the array of electrodes positioned within the cochlea. 5. The electrodes stimulate the hearing nerve fibers within the cochlea. 6. The nerve sends the signal to the brain for interpretation.
