Fireworks & gunshots, nonstop

I moved here about a month ago, for work. I'm on the west side. My neighbors have been shooting off fireworks / guns / ....cannons?!???? since 5pm. The amount, and the variety, of booms and bangs - is bonkers. It literally sounds like a warzone. I gather that this is a cultural difference, and that I am the newcomer, so I have to accept it - that this is how folks celebrate here .....but who can enjoy this? It's been 7 hours of this already. I admit I'm not the world's biggest fan of 30 min fireworks shows, but I can see the appeal. But what on earth is the appeal of this? It sounds so close to my home. It's downright disturbing.
