I'm amazed my hearing is what it is, although it goes silent after about 15-16kHz. I remember being partially deaf for a whole day after seeing Dio play in 1987 - we were right at the front next to a giant speaker and it was ear splitting. I still can't believe, they won't let you take drugs "because it's for your own good" but they have no problem letting people - even children and teenagers - attend events which are almost guaranteed to permanently damage their hearing.
Then I was in a thrash band for a while, and the 4 hour practice sessions in a small room standing right next to the drummer probably did some more damage. After that it was the whole rave era and I attended deafening raves and parties almost every other week for a few years, out of my head on drugs of course and dancing away next to huge speakers as a 303 bass line with a resonant filter vivisected my eardrums.
And of course over the years I've probably abused headphones a lot. I blame the whole lifestyle of smoking weed for that. You get carried away with music through the cans. In fact I'm pretty sure the tinnitus I have today began with the release of DJ Shadow's "Endtroducing" album in the 1990's, which I listened to on cans non-stop with a doobie in my hand for a good few weeks.
Then I've had 15 or so years in NYC, taking the subway multiple times a day and having my ears assaulted by screeching train brakes. Not to mention all the fire trucks and ambulances which pass me on the street every day, not all of which I remember to shield my ears from. Oh and I always end up having to walk past at least one jackhammer every day, those are pretty brutal.
I'm surprised I'm not profoundly deaf to be honest. I think it's the large supplemental doses of magnesium I've taken for years, lol.
