Kids only Ringtone
Listen to this. Apparently people over 40 can’t hear this, do to a naturally occurring hearing loss. Somebody put that into a ring tone. So kids can sneak around with cell phones in school with out get caught. Check this at the NYTimes (registration required).

I actually tried this test and I got down to some pretty low levels but this is interesting. Thanks for sharing.
