I randomly wondering what is the exact note, frequency and volume needed to make The Brown Noise and is it possible to be made on the computer, or does it need a certain instrument?
If your not aware of The Brown Noise, it is a sound that can apparently make you immediately shit your pants as soon as you hear it and the same to all people in a 5 foot radius depending on the volume of the sound. Some people believe it is none existent, yet it has been done to somebody live on television.
Also it doesn't work on all people, just some, depending on their diet and when they last ate.
It apparently works by vibrating the bowel in a similar way to diarrhoea
I believe, if Im right in thinking this (please correct me if Im wrong) but the Brown Noise is a very real thing, but very hard to make. It is a ultra-sonic frequency, lower than 50 hertz. It is not differ depending on what you ate, or anything like that, it depends on the pickup rate and how accurate your ears are, and what your brain wave patterns are. I believe that someone with "average" brain wave patterns is affected by a sound such as this, but not only does this trigger things like diarrhea, but it causes the body to have a muscle spaz, making the muscles such as the rectum and esophageal muscles to release causing diarrhea and vomiting along with various other symptoms.
O i see well i got some of my facts right at least, is there a particular note or is it too ultra-sonic to create as a note?
it is possible to create this noise, but you must know the exact frequency, and have a very good generator, idk if a computer can do it.
Not sure on the reliability of these guys, but i saw an episode of Mythbusters on this exact topic. They ran through every frequency they could come up with. Some massive speakers, nothing happened. A little nausea from so much sound acting on the body, but nothing like what you're describing.
I don't believe that they would have had the requisite equipment to produce The Brown Noise. It's a very uniquely generated frequency. And while I don't remember the specifics of its generation -- it's been four or five years since I was shown its effects first-hand -- I do remember that it wasn't using any off-the-shelf components.
According to Military Research, it varies from person to person. The military has found that the only one possible to recreate with technology only affects 1.003 percent of the world populaton. They are made naturally by rare forms of underwater volcanoes. Shellfish are immune to all brown notes.

If it is lower than 50 hertz, shouldn't it be infrasound? I thought 'ultra' was for energy levels too high to be picked up by humans (eg ultraviolet) and 'infra' for lower (eg infrared). I would have thought 50 hertz was a fairly low-energy sound.
I heard that it was 92 cents below the lowest octave of E-Flat. Think I heard it from a 4th grader.

I wouldn't totally believe that. They neglected to consider the principle of superposition of waves. To me it seems plausible that a 'brown note' could in fact be a hybrid wave rather than a pure sinusoidal wave.

Yes, but AFAIK humans can hear in the approx. range 20-20,000Hz, so 50Hz would in fact be audible' http://hypertextbook.com/facts/2003/ChrisDAmbrose.shtml '

Therefore it shouldn't be ultra- or infra- anything.
Could be subsonic though.

Yep,I was just agreeing with you that it would be infra- if it was lower than the limit.

Sound travels at sub sonic speeds? Cool! [/sarcasm] (Given the same medium of course)
My my my, did I have an exciting morning! At the behest of our director of research, I spent this morning at the "laboratory" where I first encountered this mysterious tone four years back. I'm using the word "laboratory" quite liberally. The man has a workshop he's built in his garage. He works as a chemical engineer during the days but has a passion for the study of diaudic acoustics. He's an acquaintance of mine and he has been studying how the body reacts to The Brown Note on-and-off for about nine years. In addition to a demonstration which was luckily unsuccessful this time, he was able to provide me with the following information:
• When produced by his equipment The Brown Note affects around 28 percent of the subjects he's tested it on.
• The Brown Note is produced through a combination of beats (produced when two sound waves combine to create a third, more complicated waveform) and the doppler effect (produced by the compression and expansion of sound waves coming from a moving sound source).
• The Brown Note is not a single tone, but a series of tones that must be sequenced correctly for the desired (undesired?) outcome to occur. Its peak intensity, also the time when most test subjects "loose it," comes at the moment when the sound source switches directions.
• The Brown Note doesn't work by vibrate the bowels, per se. Instead, it causes a resonation in the spine of the nerves that control the bowels, triggering its expulsion reflex in roughly 1/3 of test subjects.
All in all it was a very interesting morning, but not something I'm too eager to repeat. There's a certain element of uneasiness associated with being in the presence of such equipment. I can field any questions you might have, but I'll be passing the more technical ones along to the infamous "Dr. Brown"
