Its much more common for hyperacusis to get better, or to even recede, than tinnitus thats gone into the so called chronic stages (6 months +). BUT, going back to the same lifestyle you had before (if you loved loud music, clubs, concerts and such) is a bit of a gamble. Your auditory and nervous system has been compromised one way or another. Just a word of advice.
It's only when you start getting a lot of pain in the mix things get iffier but even that usually improves to some degree.
