Potential ways to torment the new neighbors who sit outside our living room going "hwwwaaaa"

We used to have quiet, lovely neighbors whose only fault was that their cat shat in our horseshoe pits. But we were able to deter such occurrences, and never had any other quibbles with them. They were quiet, their dog was quiet, and they didn't sit just outside our living room going "hwwwaaaa." The new neighbors sound rather like Beavis and Butt-Head.

It was 18 degrees last time I checked. Why would it be preferable to sit outside than inside? Perhaps the fusion jazz we just played loudly for 20 minutes will help to return them to their senses. Other suggestions?

Fusion jazz? What is that like, exactly? If they're Beavis and Butthead, maybe play acid rock instead of what sounds like music to go to sleep to? :-)

I've always wanted to have a focusable noise generator capable of going from 40 HZ (just below human hearing) to up close to where bats make noise. And then be able to amplify and modulate and pulse just to see what kind of reactions different targets would take when under assault.

Matt, do you know what google is? Or wikipedia? Yes, I know I'm a librarian, but you're also a veteran of the "look-it-up" parenting plan.

Dad, you are kind of evil. I like it.
