not sure how you mean it...but a CI (cochlear imlant) does not "plug in" to his head.
There are 2 parts. The implant which stimulates the hearing nerve via being implanted in the cochlea
and the second part. the part thats visible on Rush which is the computer.
The computer simply rests on his ear like a hearing aid. The microphone is located on that longer straight thin peice that runs along the front of his ear. sound goes in the microphone travels to the computer where it gets fancied up travels to the small piece on his head where it gets transmited via radio waves through the skin and to the implant.
there is nothing "plugged in".
just some friendly clarity brought to you by the parent of a child that has one :)
Thank you. I knew you would have the technicalities. Plugged into his head, lol.
