will the police inform the noisy neighbours?
If these neighbors are renting then the traditional way of dealing with it is to contact the administration so that they will inform the owners that their tenants are annoying other residents and the owners deal with them (maybe kicking them out).
A couple of times that's happened to bad neighbors in buildings I've lived in (I did nothin' it was the other neighbors)
If they're really a bother that may already be happening.
