The hard work re Cochlear Implants is all the sounds you didn't hear before. Item: for me: hearing myself walk down the street and not thinking-someone is following me. Yeah-silly isn't it?
The length of time one was DEAF-silence-to Implantation. The longer period -more time needed to get Use to hearing sound-again.
