Earlier quoted context omitted.
Tinnitus is sometimes neurological, seemingly caused by the brain compensating for a loss of sensation. I can imagine a horror story in which this just makes it a thousand times worse, on top of permanently losing all hearing. Now, being able to use a hot-swappable audio sensor instead of an ear made of tissue would be pretty dope.
I hear that theory but I don't believe it - I have tinnitus. Nothing else in the nervous system behaves that way - lack of light doesn't suddenly make you see blinding light etc. It's much more likely the sound sensor in the ear is jammed in the on position.
But if you are one of the "common kind", which is typically an insult to your hearing apparatus that damaged your cochlea, then the work from Susan Shore [2] is a reasonable explanation of what could actually be going on (genesis by the fusiform cells of the dorsal cochlear nucleus). You may be interested in checking out her publications listed in the wikipedia article quoted.
