I am not really too sure that anyone knows why. I think one theory that I heard is that neurons filled the void from frequencies that or below and/or above that are still functioning.

@Ryan Scott that "makes sense" as much as T can make sense. Wish so badly my brain didn't care so much about losing frequencies that aren't even important/needed for speech and the general world around me ;(
@ErikaS Agreed. Having some form of hearing loss is bad enough why does tinnitus have to be a side effect lol. Its a shame tinnitus has just gotten clinical/research interest in the last couple decades, otherwise we would probably understand it much better.
@Strawberryblonde hmm, that would be interesting because I have shown "perfect range" at the frequencies that I hear these noises/sounds at, all being between 1500-2500 hz which are in speech range as well and I have no difficulty with speech. Then again when does T ever make sense? Lol
@Strawberryblonde That is correct you can have hearing loss at low frequencies that don't show on a standard audiogram. My understanding is audiograms test at the frequencies shown on the X-axis and not between them. It's not like a calculus function that gets evaluated from 0 to the limit.
I guess I should have said none of these are straight tones. These lower frequency sounds are like morse code and bounce around different notes.. so WHO KNOWS where they came from and WHY they won't go away ;(
