Sound f*cking rocks. I love physics.

So they're just shooting two ultrasonic waves at the listener...that's brilliant. I can't wait to see this stuff in the mainstream, that could be incredibly useful. Of course, I wonder if it distorts the sound at all. It'll be interesting to compare that audio to some nice speaker set ups avaliable now. The science behind noise-cancelling headphones is incredible as well. I've been meaning to get me a pair of those, but good ones are a few hundred dollars.
