The hearing is fine. I have hyperacusis to the 4k frequencies when I get exposed to industrial noise. The other day, for example, was bothered by a leaf blower that was droning on from 5 houses away. It was not loud and <70 db, but still damn annoying and needed earplugs just to tolerate it outside while I had some work to do in my garden.
Is there any other sound from any other frequency that gives you discomfort/pain?
