That's a problem. Because there doesn't appear anything you can do about it. The neighbors don't care about you and that shouldn't be a surprise as, in my experience, no neighbor gives a flying damn about anybody else. A good neighbor is one who keeps his mouth shut while the other neighbors turn the neighborhood into a hell-hole. If you called the police about a crack house the dopers would hate you and tell you to get a life too.
They have expressed their contempt for you by their "get a life" comment. Of course they would say this to *anybody* who complained about their noise, not just you.
Good luck to you.
Throw your shit in thier pool everyday.
Are you sure that there are no town/city codes concerning noise levels? I live in a small dirty, nobody cares town but even we have codes on the books concerning noise. I would check with your local government before I gave up on the noise. Also check with a lawyer, some states have a "right to enjoy property" or something like that, you may be able to sue the neighbors and city/town.
here's a thought...buy boxes of unflavored ex-lax, or bottles of clear laxative. dump in the pool. eventually the noise makers will get the shits.
or you could dump in dog and cat shit
