I don't want to sound incorrect anymore, what i mentioned about painful hyperacusis being caused by outer hair cell nerve fibers damage triggering cochlear pain activators is still a hypothesis. It's definitely what causes cochlear pain to activation to overly loud 120db noise, and with the benefit of the doubt I really do believe it has something to do with painful hyperacusis, but its probably the case where there are more aspects at play that aren't understood, maybe a missing neurological element?, we don't know.
i just wish there was a more complete working model of hearing loss tinnitus and hyperacusis and all sorts of other neurological phantom conditions with organized classification and explained in detail instead of pieces of the puzzle scattered. Where as 20 years ago the pieces of the puzzle were no existent.
One day all this stuff is going to be classified and it's going to be a vast amount of knowledge that can be explained rather simple. I just hope that day comes sooner then later
