Yeah, I've got it bad. 25 years of techno/D&B with 1MW (really) sound systems in enclosed spaces. Ear protection sometimes. Ruptured an eardrum once. I was surprised to read about some of the really negative reactions to it. Mostly, it's like white noise to me and I'm able to ignore it, but whenever it's bothering me, I think back to some of the good times I had getting it :)
