A cochlear implant will not guarantee diminished tinnitus. I had a CI last Friday and tinnitus is all over the place at the moment. In the night it is horrible, in the day sometimes goes back to where it was. Just hoping it stabilises. However most people do say that once the CI is activated the tinnitus is much less noticeable. My fingers are crossed. The equipment may well be covered by your hair and so may be no more noticeable than a hearing aid. Frankly, if I can hear people can look all they want and maybe get educated along the way.
