Can you hear this sound?

Click through to this web page and test whether you can hear a sound that supposedly can only be heard by young people. It's said to be used to drive teenagers away from malls. It could also drive listeners away from your radio program. The site allows you to download the sound, so you might like to use it for EQ (equalization) practice. Audacity has an equalization plug-in under the Effects menu on the toolbar. High-end rolloff would probably cut it.

By the way, I can hear the sound so not all older people lose high-end hearing. If you hear it when you're not even listening to the computer, google tinnitis.
