Quick Facts:

Cochlear implant sounds are not like normal hearing. Initially, they only allowed the detection of noise but pts were unable to understand speech. As improvements have been made many patients are able to understand speech with the assistance of visual cues and some can even use the telephone however large variability exists in response to these implants.
