The array is a bundle of tiny wires that have electrodes that spread out along the length of the array. The array is inserted into the auditory portion of the inner ear (cochlea). The electrodes send electrical signals from the internal device to different areas of the cochlea to represent different sound frequencies. A sound processor contains a microphone that detects the sounds in the environment. Sounds are digitized by the sound processor. Small sound processing units can be worn behind the ear, or modular options are available and can be clipped on to your child’s clothing. A magnetic headpiece sends the digital signals from the sound processor through the skin to the implanted device.” Although it sounds like a lot of equipment to deal with, it is very easy to manipulate.
