Here’s how the implant works:
The microphone picks up sound.
Sound is sent to the sound and speech processor.
The processor analyzes the sound and converts it into an electrical signal. (The signal contains information that determines how much electrical current will be sent to the electrodes.)
The transmitter sends the signal to the implant package, where it’s decoded.
The implant package determines how much electric current should pass to the electrodes and sends the signal. The amount of electric current determines loudness, and the position of the electrodes determines the sound’s pitch.
The nerve endings in the cochlea are stimulated and the message is sent to the brain along the auditory nerve.
The brain interprets the sound and the person hears.
