Standing waves..

[jasno]

I wonder if the individual experiences were determined by the location in which the listener sat. It would seem that standing waves could form, with some people getting blasted, while others feel nothing.

Not a very technical article, but interesting nonetheless.

Practice makes rejects

Sixth Column

[Kafir]

In Robert Heinlein's Sixth Column the good guys (defending America against Pan-Asian invaders) use "subsonics" to make people uneasy. That's what this study says "infrasound" (same thing, different name) would do: make people who were already nervous more nervous, without their knowing why.
I assumed this was already well known science; the other possibility is that Heinlein was uncannily prescient (even for him.)
Anyone have more background on this?

Actually, there is a note called the "brown" note. It's a tone that causes humans to lose bowel control (I don't know if this has already been mentioned, I read comments at a level 3 or above rating. Yeah, I'm lazy, fuck you trolls *thwack*). There are also tones that induce vomiting, nasal bleeds, and lung failure, heart failure, and epiliptic seizures in non-eplilectis subjects. It has to do with the tonal resonance on the cells and other such meat space stuff. There are a lot of things that cause sympathetic vibrations in matter. Most people are not aware of this, but if you live in a large city, the feeling you get when you are out away from civilization (like I mean, out there, away from power lines a must), is the lack of the low tonal B vibration caused by the 60 (or 50, or 47, or 78, depending on your country of origin) in the air. Electricity flowing through power lines in power grids causes a tonal vibration that can actually be measured by human senses. You can actually feel the difference.
As an anecdotal reference, I was travelling cross counrty (USA), and was out in the desert (no power lines within several score miles). It was peaceful. It was quiet. My senses felt jazzed and alive, mainly because they weren't constantly being bombarded by that 60 cycle hum of electrics around me.
Anyway.
So natch.

Binaural beats?

[majestynine]

Binaural beats (stfw for loads of info) work by causing the brain to 'hear' the resulting frequency which would normally be outside of the human range of hearing (ie 4hz).

This is done by playing two different frequencies into the different ears (ie 300 hz into one ear, 304 into the other: your brain then entrains to a 4hz frequency)

Does anyone have any idea if this device could remove the need for the two frequencies by simply generating the Such things would be useful for brain washing, because if a speaker can put his audience into an alpha state (2/3hz), then they are more susceptible to impressions (thats why many religions use repeditive beating drums in their rituals etc)

Ben Hur

[jmichaelg]

My father was a teenager in Los Angeles during the 20's. Years ago, he told me that the director of Ben Hur (I think the 1925 version) wanted a scene of a crowd stampeding. Since the crowd was comprised of extras who didn't have a lot of acting experience, the director induced panic by playing a note on a 20 foot long organ pipe. The note was infrasonic and generated a level of unease that the extras couldn't identify but when instructed to run, they willing complied.
