The Teenager Audio Test

There is a sound frequency which can generally not be heard by those over 25 that is used to keep teens from loitering in malls.  Go here and play it to see if you can hear it or not.  I'll warn you though, if you can, it's annoying as hell.  I'm interested to try it out again the end of this month when I'm 25.
