This application is designed to play sounds that will get those pesky kids off your lawn. Fun for messing with coworkers at the office or testing your hearing, Get Off My Lawn is purely for fun.
Select an age range to test the frequency and hit the button. If the button turns green, its on. If you dont hear it, thats because you are too old (or just cant hear that frequency). Try it on someone younger and see what happens next.
