My experience has been with a church, which refused to keep things quiet during revivals. So depending on whom your dealing with use this with caution as you can start more issues than just dealing with the noise. Also first thing is to always try and talk to the person(s) calmly and choose your words carefully. Mentioning sleeping kids can also help. The police can be helpful infrequently, more so the poorer the neighborhood you live in. And also some people/groups are going to get preferential treatment over others from the police.(Yes, from experience) On multiple occasions police in my old neighborhood refused to enforce local ordinances, and other laws being broken by the church I lived next to.
However, if everything else has failed, be a prick. Find the Panic button on your car, press it and wait. Within 10 minutes the revival group I had been dealing with started packing things up and continued to do so about an hour early every day. When they had been playing until 8PM in a residential neighborhood they started packing things up by 7 as I had already politely asked them to do, but to which they initially refused.
