To play the devils advocate here. What time is a musician suppose to practice? In most municipalities 10pm is when loud noise making should stop. If someone plays Bag Pipes or a Sax they’re not allowed to practice?
After 10pm I’d call the cops, but 9:30 pm I’d grin and bare it. Just like those idiots down the street with the huge subwoofers in their cars. After 10 I’ll call the cops on them before 10 I turn up my stereo or put in IEM or something.
On a different thought your post made me think that maybe you live next to Rufus Harley,
http://en.wikipedia.org/wiki/Rufus_Harley The worlds only Jazz Bag Piper. I am saddened to report that he passed away this July. The world is a lesser place.
