Mosquitotone

Over at the blog, ringtonia, they are reporting that a high frequency sound that shopkeepers have been blasting out of their storefronts has kept teenagers away. The curious part is that people over 20 can't hear it! Kids hear a high-pitched mosquito noise while us codgers hear nothing but the wind in our vanishing hair.

Test for yourself.

Now comes the news that the sound which was designed to keep kids from hanging out at the 7-11 gas pumps has been turned into the perfect stealth high school ringtone! Your 35-year-old teacher will never hear it.

Neither will I. Brilliant.
