Buy a DB meter, measure the sound, before you call the cops. Over a specified level they should, might not shut them down considering ethnics.
I have to wear shooting muffs to go to the grocery store, after I pull my hearing aids. As it is to loud and will damage what little hearing I do have left from 2 Meniere’s attacks. 1 more I’ll be Deaf, with NO FIX.

Industry has DB levels set, over it they have to provide hearing protection.
Restraint’s, shops, grocery stores, concerts which can exceed 120 DB don’t, fall under this. And can damage your hearing.
I think talking to them is the best option, but it isn’t the best option for everyone or every situation.
Barring that, I think the DB meter is appropriate.
