Outdoor sound deflectors

[Cosmickt]

Please help Need Some kind of equipment to place outside my home to deflect/reflect sound BACK to my drunken/wild teenage neighbors & parents so they can mostly hear themselves and I am not forced to call cops and suffer retribution. Please. I'm 70 now and area has high sound envelope. Isn't there some kind of parallex-producing disk like object out there that would reflect sound back? Can I somehow reverse/ use my old Dish antennas? Kkkatie
