With good reason. I don't know how old you are but I am in my 50's and used to carry an SPL meter with me to shows. Did it a couple of times. It was an old analog type that a top range of 110db with a +6 to top the scale off. Went to one show. When the band started up it pegged the meter at 116DB and it never came down. It was so frickin loud it was almost painful. We got the hell out of there as it was no fun at all. That's not loud that's downright abuse.There was a post earlier this year that discussed a sound reinforcement issue that alluded to local SPL ordinances that preclude sound engineers from cranking the system.

Have a read it touches on this issue.
