I don't know if anyone has heard of this but they came out with a device to deter teenagers from loitering by playing a sound at a certain frequency that people lose the ability to hear around the age of 25. It's supposed to be annoying to all of the young kids who can actually hear it and the adults go about there business without even realizing what's going on. I'm 27, so I wanted to see for myself if I could hear it, and I couldn't so I guess that part of my hearing is gone for good. More interestingly I read an article today saying that kids are now using this sound as their ringtone in school so they don't get busted by the teacher who can't even hear it. Two hypothetical questions arise:
1. Can words be transmitted in this frequency so only young people can hear it?
2. Can this annoying sound be played on giant speakers and cripple bad youngsters leaving adults unharmed?
If you want to check the site out and see if you can hear the sound the link is
