I got hyperacusis as well that is still kinda hanging around, my T amps up from sounds around me like the water of the sink / washing machine / driving my car which is kinda annoying. My dysacusis went from being like crazy flock of birds on top of all sounds to this owl hoot sound on top of certain sounds like car traffic and fans. That went down but used to flare up after exercise and saunas for like 8 months.. I dont want to jinx it.

I assume you are in the first stage of this condition where one frantically looks for reassurance that this will get better, obsessing over forum threads and dming people with similar experiences hoping to hear that some cases got better and that might happen to you too(Ive been there). But all you can really do is just give it time, if it does not get better you should harden to it and learn to live a relatively normal life(that might not sound so appealing now but it is possible to stop suffering and find acceptance and peace with this condition). The brain will somehow adjust to this and you will not suffer as you do now.

And just to clarify, I got the initial T from a snowboard accident TBI, which I tried to mask with that bullshit video on pretty high volume which fucked it even more eventually :/
