Needing resonant low audio frequencies that affect the human body.
White papers, tech notes schematics and applications would be fine.
We would like to trigger a bio response capable of going through
walls, specifically targeting the large intestine to cause
discomfort.

And y'all aren't smart enough to search the WWW. Good luck.

Doesn't work so well, not unless you're prepared to cause structural damage.

It's possible for something in the 7 Hz range to cause discomfort if you
can move a whole lot of air. But if you want it to go through a wall, you
need to do that by moving the wall back and forth, and walls don't like that.
Otherwise you wind up just coupling all the vibration into the structure
and just moving the floor.

There actually IS a Naval Research Lab memo on low frequency sonic weapons,
from WWII. It basically concludes they are not effective except in a
couple very specific environments.

Sonic weapons are in light use in Iraq and Afghanistan, and were
on standy and visibly present in the streets at the 2004 and 2008
R N C.

And BTW... protestors arrested at the RNC this year were charged
as "Domestic Terrorists".

Yes. These aren't low frequency devices at all, though.

What were the ones arrested at the DNC charged with?

Wimps.
See, apparently Democrats are even better protesters. :-)

You might like to try and search alt.sci.physics.acoustics.
I read a paper there by Geoff Leventhal that had a graph showing adult
male chests resonating at 50hz,107db.
I guess when your ears go, you can experience vibration through your
chest.

Paul,

Some spook once told me that 7 Hz is the resonant frequency of the anal
sphincter..or was it 4 Hz?

He suggested they might have used it to cause evacuation during
interrogation.

I wouldn't consider this the last word, but the Mythbusters episode
result was "busted."

Panache of the Meyer name notwithstanding, I did not think that it was the
best possible effort.

You're talking about the resonant frequency of the abdominal cavity.

Yes. It varies a lot from person to person because people are all different
shapes and sizes, but in general it's something in that region.

The bad news is that it's not easy to send a big 7 Hz wave a long distance
outside, or easily send it through a building. A lot easier to do it in
a sealed interrogation chamber.

In general, lots of low freqencies can cause people to become very tense
end edgy... and that's another thing that people doing interrogations like.

I do wonder though if the cue tones on commercially pre-recorded cassette
tapes would be in this 7 hz range..they could take the easy way out and just
loop the cue tone.
