Do you still have the hyperacusis?I have had hyperacusis for fifteen (15) months and tinnitus for almost as long. I have not overprotected and have exposed myself to normal, everyday sounds. The hyperacusis and tinnitus have not improved and the tinnitus seems like it might even be worsening. I am wearing above the ear sound generators and listening to pink noise each day. It might be aggravating my condition but my tinnitus seems reactive to running water, paper/plastic bags, turning the key in a lock, squeaky floors, etc. I am also still having a lot of insomnia which has been a problem since July of 2020.
My hyperacusis from the SSHL has subsided. It didn't fade overnight. It is a gradual process. Someone told me his therapist told him to not wear earplugs all the time and that the more he was willing to expose to normal sounds, the faster his recovery. So I didn't protect my ears with earplugs as often this 2nd time around with hyperacusis. So it seems to have faded away sooner this time.
But everyone is different. Use prudence with your own situation.
Best wishes. God bless.
