Thanks alot guys, you gave me another problem I never knew I had
Never even remember hearing the word before, and definitely didn't know what it meant, til out of curiosity I clicked on this thread.
Now I definitely got it!
I am the perfect candidate for it apparently, using jack hammers all my life, for hours at a time sometimes day after day. I do basement drainage work and have to cut through the concrete floors. we use electric jack hammers so not as bad as air but they are still quite load.
I almost always use ear plugs but sometimes not and back in the day not as much, I even use ear plugs when I mow the lawn now.
I think some of it must be psychological, like I said I hardly ever noticed it but now that I'm thinking about it, it's much more noticeable, between a hiss and a ring. If you concentrate on it, it gets real load.
I didn't read to many posts here but got the gist that there's no real cure? good thing mines not that bad yet, I will definitely start being more cautious and maybe get some better hearing protection than just those foam plugs. My hearing overall doesn't seem to be affected (no hearing loss).
