A decent and easy test is whether you can tell if the TV is on in another
room with the volume off. TVs produce a tone around 15KHz I think.
OK, closer to IDM content: At the end of Ryoji Ikeda's +/- there is a
tone which supposedly a listener becomes aware of only when it stops.
Well, I can hear it the whole time. (Hint: wear earplugs at concerts!)
Sorry if I'm beating a dead (and off-topic) horse...
