if it is after an acute noise exposure, i try to super protect my hearing, and in between 2 months to 8 months, it might ease up a bit. my last noise exposure was from the dentist grinding my teeth to make crowns, and it took 3 weeks for it to ease up. it went from life-ending where is my nembutal, to I'm so glad I got my mojo back. It is still moderately loud, but at least it is not "catastrophic" where it is the end of my career etc.
