When I was younger my family was living in a town house. My brother and I are both HOH and don't realize we are too loud sometimes. Our neighbor reported any little loud noise to management and eventually to the police. We tried everything to keep quiet, eventually we felt like we were always on our toes trying not to get a complaint. The worse part was that they were louder than us. There was nothing we could do to get them to stop complaining. The only way was to move away and get a house, which was the best thing we have ever done.
I am sorry you have a whiny neighbor. I am pretty much sure it's going to be one of those "either he or you move" situations.
