I've heard of a certain tone called "The Brwon noise". Its said that it's spots' to make literally make you puke or you the bathroom. it might be made into a weapon as well. I heard this video on youtube at http://www.youtube.com/watch?v=hc2DbWGZmN0

When i listened to it, i had this fealing in my stomach and my arms kinda' hert. Im not sure if that is the ACTUAL nosie but, it would be neet if Mythbusters could look into that mabey? The Brown Noise

They already busted it.
