I can sleep at Burning Man with ear splitting sound camps blaring mere feet from my tent. It's called earplugs, they work well and they're very cheap. I've used them to equal success at home on the Fourth of July, too. It simply isn't a big deal. Let Cletus light firecrackers and work on his car in his own drive way. Who the hell are you to tell him otherwise? Go live in an HOA if you want to tell your neighbors how they can and can't behave on their own property.
