My brother (late 30s) is the same, he's still bothered by anti-teenager and anti-bat repellent gadgets, too. Cracks me up every time. And he listens to more metal and attends more shows than I do, too.
Those repellents bother my kids as well, and they're everywhere apparently but I can't hear them. Permanent tinnitus from far too many loud concerts in my 20s and 30s. All I can say to younger readers is: wear earplugs. You won't appreciate not having tinnitus until you do, then it's permanent :/
