Slide 5 of 12
1. Sounds in the environment are picked up by the small directional microphone.
2. A thin cable (cord) sends the sound from the microphone to the speech processor.
3. The speech processor amplifies, filters and digitizes sound into coded signals.
4. These coded signals are sent from the speech processor to the transmitting coil via the cables.
5. The transmitting coil sends the signals across the skin to the implanted receiver/stimulator via an FM radio signal.
6. The receiver/stimulator delivers the correct amount of electrical stimulation to the appropriate electrodes on the array.
7. The electrodes along the array stimulate the remaining auditory nerve fibers in the cochlea.
8. The resulting electrical sound information is sent through the auditory system to the brain for interpretation .
