Mosquito ring tone
My dad told me about this. I hadn't heard of it. It's a cell phone ringtone that is pitched at a frequency that most people over 30, supposedly, can't hear. It's based on a device that is used by British shopkeepers to repel unwanted teenagers from their stores.

I can hear it, but barely. It's definitely at the very upper limit of hearing for me (and incredibly annoying -- it's like the high-pitched whine that some electrical equipment makes, such as an old TV set). Now I'm very curious what it sounds like to other people.

I tried it at various volumes as well. Cass never heard anything, but it quickly became physically painful for me when I turned it up. One strange thing was the aftereffect of blasting my ears with it. It really had a lingering unpleasant sensation. It's tough to describe in familiar terms, and I'm a little reluctant to repeat the experiment to search for a better description.
