It's worth asking your local council if they'll get involved.
My friend (who isn't exactly a 'hell raiser' - she's 77!) received a letter from the local district council, stating that they'd received a complaint about her dogs barking and her TV being too loud. (She's since got a couple of hearing aids, so hopefully that won't be a problem in future). If nothing else, it show that some councils will at least write to people who create noise. (That might be all that is needed).
