I went to an Ozzy concert years ago, and damn am I ever glad I thought about ear plugs. We were about 30 feet from a stack of cabinets. It was loud. Enough that certain notes made specific internal organs vibrate in a way that could easily make one panic haha.

Even with the plugs, my hearing was super-numbed for hours after we left.

I agree also, that I think ear buds are part of the reason. People don't ever take them out, and that constant sound pressure can't be good.
