This cochlear implant looks much like the one I received at the age of two.  It did not wrap around my ear, but rather was a long cord that extended to a processor wrapped around my waist.  As I was too young to process when the battery would die, it would beep to alert my parents that my battery needed changing.  After I received my cochlear implant, I endured years of speech and hearing therapy.  My nerves had been dead for so long that my brain needed to learn how to hear.
