> I wear good ear protection, though, and feel no pain.

Yeah, I've got a variety of Etymotic "concert" ear plugs (mainly ER20s), a collection of Loop ear plugs, some from Flare (titanium, aluminium), and various other of differing construction that live in my "gig bag" (small bag that holds phone etc. without causing security to freak out.) I find that if I don't wear ear plugs at a gig or even the cinema, I'll have terrible pain overnight and I'll be useless the next day.

(Hell, even bus or train journeys can require ear plugs some days.)
