I definitely have hearing loss, despite always wearing hearing protection at every concert or band practice. The loudest concert I was ever at was Lynch Mob in 1991 or 92. My ears hurt badly WITH earplugs, and my entire body was numb for 2 days. It was about a 2,500 capacity club. I don’t know how anyone survived AT ALL without plugs.
Then, for years, I had a drummer that would mash the shit out of a China Boy cymbal just a few inches from my head (small rehearsal room) whenever I wasn’t watching. That got me too.
ALWAYS wear hearing protection, guys and gals. I can’t stress it enough. Once your hearing is diminished, it will NEVER return.
