Hehe, they had an experiment using 'brown noise' on Brainiac: Science Abuse (a humourous science show they show here in the UK).
Anyway, they even got viewers in on the test. They transmitted the brown noise (so you could hear it through the TV) and asked viewers whether it worked or not.
Naturally me being a sissy I muted the volume just to be on the safe side.
I could see it making a good interrogation tactic or perhaps even a weapon.
Just for Sh*ts and Giggles, pardon the pun. Does any body have a audio file of this "Brown Noise" I'd love to see it uploaded, so people in the privacy of their own home test it out. I can blame the outcome on something else for the sake of brevity, if it works, lol.

I don't think that would be possible, no home stereo equipment can handle frequencies that low. And certainly no TV speakers.
Even high end recording/audio equip usually can only handle down to 20Hz.
Also human hearing is in the 20Hz to 20Khz range, so you can't HEAR anything bellow 20Hz or above 20Khz.
But with a big enough amp and speakers (Huge magnet and cone travel) designed to handle VLF you would still not hear it but you would FEEL it.
The thump you feel, but not really hear, from the kick drum/bass on dance records in a loud club is around 80Hz.
Here is a 5Hz to 40Khz sweep. It's in WMV and MP3 format so the quality is not that great. You will here silence until it hits at least 20Hz. If you're over 30 and work/live in a noisy enviroment you wont even hear 20Hz.
If you have equipment that can handle the 5hz have fun. But don't hold me responsible...LOL
