Something About This Made Me Feel Young

I have heard about this noise that supposedly only people under 25 can hear and some stores in malls are using it as a deterrent noise for teenagers and their ilk to keep them away *cough* Thomas Kincaide Store *cough* as if they needed a noise.

But I thought I would try to listen to it and lo and behold, I can hear it. Yay for young ears!

Can you hear it?
