> I remember reading this story about some woman in a scandinavian country who chose medical-assisted suicide because hers was so bad.

I'm surprised there is not some method to surgically disconnect the brain from the ear.

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.

Louder than you think, Dad! Louder than you think!

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.

There are various explanations about the genesis of the sound for T sufferers, and it obviously depends on the kind of T that one has (this chart [1] helps navigate the variants).

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.

Amputees have phantom limb sensations including pain. I believe this is more than theory. Certainly medical science has collected at least some case studies over the past century about people who have had their auditory nerve severed for one reason or another. And, as I recall, the auditory system actually does behave unlike other parts of the nervous system like vision which is more mechanical and less dependent on the brain for basic functionality.

Well, perhaps some but I don't think it's the usual cause. Phantom limb isn't just loss of sensation, it's also having part of the body chopped off. Just having part of your body go numb doesn't usually cause that.

It does and it is called neuropathic pain. Phantom limb is just an extreme case of it, but malfunction or damage to nerves can cause all kinds of phantom “pain”. Experiencing phantom sensations due to nerve damage is well known and widely documented, so phantom sound in the ear due to nerve damage is well in line with that.

There is, audio nerve can be surgically cut, but this means complete hearing loss in one ear. The whole inner ear can be removed. You don't want it without a good reason.

From what I've rad tinnitus can be caused by a) shift in small transmission bones, can be age related. 2) inner ears sensors mess up, can be from loud sound. 3) something else, like infection, inflammation, inner ear pressure build up (may be Ménière's disease).

Hope technology develops fast, some sort of implant talking directly to the audio nerve. I think they already exist or are in development. This can give in theory ultra- and infra-sound sensitivity too, as a bonus.

I've read about an experimental surgery sometime in the past doing this, and the patient had no reduction in their tinnitus. Their sound wasn't generated in the ear.

I guess there might be ethical issues doing the surgery. Also it'd be quite hard to do as the nerves are in the skull up against the brain so basically brain surgery. But I was thinking if there was some way to figure which nerves were firing and kill those that could maybe fix it.

Maybe if you could stick something like a neuralink in there?
