The Cochlear Implant System
The Nucleus cochlear implant system consists of
three parts:
• Cochlear implant
• Speech processor
• Transmitting coil
These three parts work together to produce a
hearing sensation.
Sound is received by the microphone in the speech
processor. The speech processor selects and codes
useful sounds and sends them to the transmitting
coil.
The transmitting coil sends the code to the
implanted unit, which converts the code into
electrical signals.
The electrical signals are sent to the electrodes,
which stimulate the hearing nerve fibres in the
cochlea. In turn, these fibres transmit the sound
signal to the brain for interpretation.
