Needing resonant low audio frequencies that affect the human body.
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. |

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. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

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. Keith |

He suggested they might have used it to cause evacuation during interrogation. 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. --scott -- "C'est un Nagra.

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. |

So I count that "busted" as as incorrect as their bridge tale, in which they forgot to check a stone bridge sans mortar or concrete for the effect of the shockwave from marching soldiers and instead focused on resonant, bending structures.

I agree that it was one of their experiments that lacked complete comprehension of the effect. However, it did prove conclusively (at least to my satisfaction) that this is not likely to be developed into any kind of long- (or even medium-) range "weapon". In fact it seems unlikely that it could be deployed unless you could coax the victim into a specially-configured enclosed space. Which means that there are plenty of more convenient things you could do to your victim. |

But to be around the "brown-note" fequency you would have had to be inside an organ with at least 32ft (16Hz) rank, or 64ft (8Hz) pedal rank. There aren't many functioning 64ft ranks left on the planet. :-( OTOH, parents can confirm that just the process of getting kids into the car and starting on a long journey is enough to stimulate "overall peristaltics somewhat". :-) |

I don't know about the Radio City, but using electronics for the lowest rank has been widely accepted for at least 30 years. The Ruffatti Organ in Davies Symphony Hall in San Francisco being an early example (ca. late 60s, early 70s). BTW by modern standards, the EV 30W was a wretchedly incompetent device. I'm sure that there are modern 10 inch drivers that outperform it in every way. |
