Can You Hear This Sound?

Clicking the play button will produce a tone that’s usually only heard by people under the age of 25. It’s apparently been used as a deterrent device to keep teenagers from loitering. [Editor’s Note: This isn’t scientific or anything, but I tried this at home yesterday and only one of my two roommates could hear it. So either there’s something in it, or my roommate is a no-good lying bastard. Test it out for yourself and let us know if you can hear it.]
