hmmm well I'm a college student and I live in a college town so I've been pretty used to obnoxious neighbors.
We had these 4 guys across the street who were out of control. Not only were they loud but they like to yell racial slurs early in the morning (I know who does that), they also had more than one party with blatant drug use and girls screaming, crying, and cursing in the front lawn.
Well after about a month of this I decided to call the cops on them anonymously. All you have to do is call the cops and say that you don't want ur name brought up and they are a disturbance. I did this about twice and they got the point. (Also I think that other neighbor were calling the cops too)
The rest of the time they were respectful. Though we did have an incident where me and my friend went to walk to a friends house and they called us "Whores." (my friend was a male

) anyways we called the cops to teach them a lesson and the party was dispersed when I went home that night.
I hope I helped!
