Ever noticed how two notes of slightly different frequencies make a "warble" or "beating" effect? That warbling is in effect a third tone that is the difference between the two frequencies. Try boosting the two notes to Ultrasonic frequencies, say, 200,000Hz? If you superimpose a 200,440Hz tone on our 200kHz Carrier Wave, we'll hear a 440Hz tone (A above Middle C on the Music Scale). Guess what, the superimposed wave can be Frequency- and Amplitude-Modulated to carry a sound signal! And with the neat properties of Ultrasonic waves (they can be collimated into a parallel-sided beam that can stay coherent for a _VERY_ long distance), this can have some diabolical uses. When this Audio Beam hits something, it scatters in all directions, allowing everyone to hear it coming from the point it scatters from, but NOT from the real transmitter! So, if you get an ultrasonic transducer that can handle very high wattages, you can hook up a wavemixer device to do your frequency/amplitude modulation for you! Attach this hypersonic emitter to a swivel device and power it with a Kilowatt Car amp and mount the resulting Sonic Weapon to your car, and show those idiots with the Bass Cannons who's B0SS! Try aiming at your target's head (or a nearby bush/light pole/Dumpster/etc) and speaking with a booming voice and convince them you're God, or just aim the beam at their digestive system (aim at their center of mass), turn the power up all the way, send a 10-20Hz signal and watch them SHIT THEIR PANTS! Just like the Brown Noise in South Park Episode 317! This works especially good against easily-embarassed Gangsta G-Doggg Thugz who would never want to be seen with diarrhea.. heeheehee!

Yes, I am evil!

There is an ultrasonic "fear gun" I remmember reading about. Two beams intersect and play the most horrible noise the designers could come up with at something like 130 dB. The 'most horrible noise' in this case is a crying baby played backwards.
Really, this is too weird for me to make up.

Muwahahhah.

I'll take three.

Choose what the people down the street will listen to at thier next party....

Ahh, acoustic weapons, from sphincter relaxation to demolishing streets, ya gotta love sound.

There is a low frequency weapon, If you play a signal at 11hrtz, at a certain volume it causes the body to shit itself... No shit you lose bowel control

Quite similiar to the US Marines playing pop music to scare ethnic soldiers in Yugoslavia...

The disadvantage of the low-freq weapon is that itr's omnidirectional. Superimposing this signal onto an ultrasound beam in the manner I describe neatly circumvents that difficulty.

EXACTLY!!!

Let's introduce those loud assholes down the street to the Joy of POLKA!!!

I like my "Tunnel of Cutty Death" more. Not really a weapon, but not hard to make. You know those little wind tunnels full of money they put people in on game shows? Take one of those, but fill it with razor blades instead.

Today another tragedy befell Kosovo refugees when a Tactical Britney Spears album was accidentally activated on a bus.
All the passengers killed themselves.

The Brown Noise!

Haven't these things already been bult?

Exactly what I'm describing, but VERY HIGH POWERED, hence, 'Weapon'!

Tried it, it fucking HATES Mozilla. As in, it crashed out hard!

SHHHHHH!! They might hear you and think it is a good idea.

What are you talking about? It's a great idea!!! Ooh! They could mix hundred dollar bills and razor blades into the same wind tunnel! So the victem--er, CONTESTANTS would stay in as long as they could! You know you'd watch it...

I could use one of these right now...

My damn suitemate woke me up at 5AM playing something on his fricken TV. I am so pissed at the moment, I could ring the scrawny little bastard's neck.

<see rant in HOS>

It'd be good.....evolution in action

There's a few issues I see from an equipment standpoint. The power output of practically all commercially available amps drops off rapidly above 50kHz, most amps won't even go that high before their output drops to nothing. We're gonna need a custom designed amp. The transducer's gonna be a pain in the ass to make, we're probably looking at peizo-electric tweeters with a horn assembly to couple them to the air. The signal source could be scrounged from an electronics lab, and the mixer's gonna be fun too. I'm guessing that a lot of stuff will have to be borrowed from the TV and broadcast industries to make it work, but hey, I could be wrong....

I wonder, how long could a person survive in a thing like that?
