In my experience there are basically two types of noisy neighbors. The first type is just not aware of the noise they're causing, but they do want to be good neighbors and are horrified when you tell them about the disturbance. It sounds like hopefully that's the kind of neighbor you're dealing with. The second type is either too anti-social or too stupid to be capable of changing their behavior. Unfortunately I had that type of neighbor, and in that situation all you really can do is move.
