Tinnitus sufferer here. Gigs can be painful even with plugs. Certain sounds even at a low volume at just the right (wrong) frequency fuck me up. 30% hearing loss in my right ear courtesy of me being a fucking idiot and playing somewhere near 700 gigs and never standing anywhere other than to the left of the drummer and not wearing plugs.
Yeah, similiar problem here, with certain frequencies, they resonate in a peculiar and unbearable way. That said, its just nice to know i'm not alone with the problem, thanks for the replies everyone.
