How about finding out who the complainers are and pay them a visit. Perhaps there are reasons for their behavior. Probably not, other than just being miserable people, but there is a possibility. The visit might provide information about the volume level of the music in question and perhaps provide a remedy. In any case, the anonymity of these complaints would be a thing of the past. If you know who is making your life miserable, perhaps you can convince them to do otherwise. Use your imagination.
