Johanna,

You absolutely did the right thing, speaking with the neighbor first. I always believe that you go to the source first before any other measures, such as calling the police.

You, as an attorney should know there are noise ordinances in all towns. I think the cut off is 9 p.m. (but I wouldn't tell THEM that!!) If speaking with the parents doesn't work, get a petition going around the neighborhood, having everyone who believes the same as you do sign it. Then take it to the neighbors house and show it to them. Tell them that if it doesn't stop then you'll have no recourse but to get the police involved. After that, it's out of your hands.

Everyone has rights. You have a right to peace and quiet just as they have a right to practice their music, WITHIN LIMITS, of course!!

Good luck.
