The information from the microphone is sent to the speech processor.
The speech processor analyses the information and converts it into an
electrical code.
The coded signal travels via a cable to the transmitting coil in the headset.
Radio waves from the transmitter coil carry the coded signal through the
skin to the implant inside.
The implant package decodes the signal. The signal contains information
that determines how much electrical current will be sent to the different
electrodes.
The appropriate amount of electrical current passes down the appropriate
lead wires to the chosen electrodes.
The position of the stimulating electrodes within the cochlea will determine
the frequency or pitch of the sounds. The amount of electrical current will
determine the loudness of the sounds.
Once the nerve endings in the cochlea are stimulated, the message is sent
up to the brain along the hearing nerve. The brain can then try to interpret
the stimulation as a meaningful sound.
