What are cochlear implants and how do they work?

During cochlear implantation an electrical apparatus is surgically implanted into the bone behind the ear. It consists of a microphone (which receives sounds), a speech processor (which selects usable sounds) and a coil (which decodes and sends electric impulses to the electrodes). These components are worn externally.
