Here’s an idea I just came up with.
Go down to a Goodwill store and get boom box–you can probably get one pretty cheap. It will probably have a cassette player. Even a CD player will work, as long as you have CD burning capability. You shouldn’t have to spend more that $10 or so, perhaps a little more for batteries.
Record the loudest, nastiest music you can think of. BUT…leave 5 minutes or so of silence at the beginning of the tape/CD.
Get up real early in the morning and place the boom box on the offender’s doorstep. With a note saying *“I don’t like listening to your noise. Knock it off!!” *
Queue the CD/cassette, turn the volume to 11, hit “Play”, and make a hasty retreat. It may not solve the problem, but I think you’ll feel better!
