Can You Hear This?

Click here to play a high-pitched mp3. I heard a story about this on NPR. A guy in Endland played this outside of his store to get rid of teenagers. Young people can hear an annoying high-pitched sound, but older people can't hear it. For this same reason, kids are using this now as a ringtone in class for text messages. It is less detectable to the teacher than if they have their phone set to vibrate.

Roughly, if you can hear the sound you are less than 35. If you can't, you are old. I can actually still hear it. Maybe next year will be a different story.
