The sound signal is sent through a thin cable to a component called a speech processor. This pocket-sized component converts the sound into an electrical code. Next, the electrical signals pass back through the cable to the headpiece. The signals are transmitted across the skin to a surgically implanted receiver-stimulator and delivered to the cochlea through a bundle of tiny wires and electrodes. The electrodes stimulate nerve cells that transmit the signal to the auditory nerve, where sound travels to the brain.
Doctors say the sound quality is different than sound perceived by people without hearing loss.
Some children may also need to supplement their hearing ability with sign language and lip reading. Cochlear implants are approved for use in children as young as one year.
