ive just been watching 'brainiacs' and they are going to be doing an experement to see if 'brown noise' actually works.the noise is aparently 22.275hz @ -30db and when played,makes the people who hear it shat their pants.
if anyone knows someone with a sky box running into a dolby system,give them a bell and tell them to get it turned up (tell them its a sub quality test of something) and then sit back and wait...this would be great to do in a pub

Many years ago heard loads of stuff about the millitary testing audio weopons, the 'brown noise' frequecny is quite well understood.
It's the frequencies that stop your heart or make your brain vibrate that are a bit worrying!
Everything has a resonent frequency, if you can drive enough energy into it at that frequency then it ends up looking like that pilled up Chav on the Pie video posted recently.

When I was visiting an RAF base some years ago as a cadet, I was told that if you ducked under the fuselage of a Tornado when it's engines were running, the vibrations could be enough to stop your heart.

Well I've done enough ground runs and am still here. On max chat you can feel yer innards jiggle about and the power beating on your chest
Here's something of an aside I put together whilst lecturing at the SAE (school of audio engineering) - bear with me, this is my subject:
Different frequencies esp low frequencies, at high sound presure levels will cause different reactions, - usually nausia.
Frequencies the human ear can't interpret are called Infrasound.
Waves of infrasound are invisible, but slam into living tissue and physical structures with great force.
The sensation vibrates internal organs and buildings, flattening objects as the sonic wave strikes.
At certain pitches, it can explode matter.
Certain animals use infrasound. Elephants use it to communicate at distances of up to 10 miles (12 - 35 Hz.).
Infrasound is so powerful that it can be used as a weapon. It has been known that certain whales are able to stun their prey with powerful blasts of inaudible sounds. Called 'gunshots,' whales focus these powerful blasts at large squid and other fish to paralyze and catch them. In some instances, they have been known to burst their prey apart by tonal projection alone.
Distress calls from small, beached whales pushed a veterinarian back several feet in the water.
Infrasonic vibrations, though harmful, can be pleasantly stimulating in mild levels. The effects of brief, mild exposure can give a feeling of invigoration for hours. While a person may FEEL invigorated and euphoric, his body is being subjected to an elevated heart rate, elevated blood pressure, a release of endorphins, and the "fight or flight" adrenaline response. Feeling the effects of high-intensity/low-frequency sound can actually become an addiction, partially due to the release of endorphins in the body.
Depending on the pitch, infrasound can cause physical pressure, fear, disorientation, negative physical and mental symptoms, explode matter, incapacitate, and kill. For example, in World War II, Nazi propaganda engineers used infrasound to stir up anger in the large crowds that had gathered to hear Hitler. The result was a nation filled with anger and hatred.
Studies show the different ways in which infrasound affects the human body. As infrasound pitches, or cycles per second, decrease, deadly effects on the body increase. Infrasound disrupts the normal functioning of the middle and inner ear, leading to nausea, imbalance, impaired equilibrium, immobilization, and disorientation. Exposure to even mild doses of infrasound can lead to illness. Increased intensities of infrasound can result in death.
These are a few examples of low frequency (below 500 Hz) and infrasound (below 20 Hz.) levels and their effects:
12 Cycles Per Second (Hz) - Walt Disney and his artists accidentally experienced infrasound on one occasion. A cartoon sound effect was slowed from 60 cycles per second to 12 cycles per second via a tape-editing machine and was amplified through the theater system. The resulting tone, though brief in duration, produced in the entire crowd nausea that lingered for several days.
100 Cycles Per Second (Hz) - At this level, a person experiences irritation, "mild nausea, giddiness, skin flushing, and body tingling." Following this, a person undergoes "vertigo, anxiety, extreme fatigue, throat pressure, and respiratory dysfunction."
60 - 73 Cycles Per Second (Hz) - "coughing, severe sternal pressure, choking, excessive salivation, extreme swallowing pains, inability to breathe, headache, and abdominal pain" were present. In the post exposure phase, test subjects continued to cough, exhibit fatigue, and have skin flushing for up to four hours.
Electricity - In the United States, wall current is 60 cycles per second (Hz). In Europe, the wall current is 50 cycles per second. Since European current has a lower cycle, an observer can actually see light bulbs slightly flicker.
43 - 73 Cycles Per Second (Hz) - lack of visual acuity, IQ scores fall to 77% of normal, distortion of spatial orientation, poor muscular coordination, loss of equilibrium, slurred speech, and blackout.
1 - 10 Cycles Per Second (Hz) - "Lethal infrasonic pitch lies in the 7 cycle range. Small amplitude increases affect human behavior in this range. Intellectual activity is first inhibited, blocked, and then destroyed. As the amplitude is increased, several disconcerting responses have been noted. These responses begin a complete neurological interference. The action of the medulla is physiologically blocked, its autonomic functions cease."
50 - 100 Cycles Per Second (Hz) - at 150 dB and higher, "intolerable sensations in the chest and thoracic region can be produced - even with the ears protected. Other physiological changes that can occur include chest all vibration and some respiratory rhythm changes in human subjects, together with hypopharyngeal fullness (gagging). The frequency range between 50 and 100 Hz also produces mild nausea and giddiness at levels of 150 - 155 dB, at which point subjective tolerance is reached. At 150 to 155 dB (0.63 to 1.1 kPA), respiration-related effects include substernal discomfort, coughing, severe substernal pressure, choking respiration, and hypopharyngeal discomfort."
7 Cycles Per Second (Hz) - The most profound effects at this infrasonic level occur here. Seven Hz "corresponds with the median alpha-rhythm frequencies of the brain. It is also commonly alleged that this is the resonant frequency of the body's organs and hence organ rupture and death can occur at high-intensity exposures."
Scientific Applications and Research Associates (SARA) - This agency's alleged infrasound research showed, "infrasound at 110 - 130 dB would cause intestinal pain and severe nausea. Extreme levels of annoyance or distraction would result from minutes of exposure to levels 90 to 120 dB at low frequencies (5 to 200 Hz), strong physical trauma and damage to tissues at 140 - 150 dB, and instantaneous blastwave type trauma at above 170 dB. At low frequencies, resonance's in the body would cause hemorrhage and spasm/ in the mid-audio range (0.5 to 2.5 kHz), resonance's in the air cavities of the body would cause nerve irritation, tissue trauma and heating; high audio and ultrasound frequencies (5 to 30 kHz) would cause heating up to lethal body temperatures, tissue burns, and dehydration; and at high frequencies, or with short pulses, bubbles would form from cavitation and micro-lesions in tissue would evolve."
Infrasound Toxicological Summary, November 2001 - "When male volunteers were exposed to simulated industrial infrasound of 5 and 10 Hz and levels of 100 and 135 dB for 15 minutes, feelings of fatigue, apathy, and depression, pressure in the ears, loss of concentration, drowsiness, and vibration of internal organs were reported. In addition, effects were found in the central nervous system, the cardiovascular system, and the respiratory system. Synchronization phenomena were enhanced in the left hemisphere. Visual motor responses to stimuli were prolonged, and the strength of the effect was reduced. Heart rate was increased during the initial minutes of exposure. Depression of the encephalic hemodynamics with decreased venous flow from the skull cavity was observed. Heart muscle contraction strength was reduced. Respiration rate was significantly reduced after the first minute of exposure."
The Navy in America has an anti-submarine device called Low Frequency Active (LFA) sonar. It emits 240 dB. Damage was possibly done to whales and dolphins, causing them to beach. Whales avoid areas with 120 dB or above. The Navy sets 140 dB as the maximum level of safe exposure to humans.
Long pipe organs, such as those found in churches and cathedrals produce infrasound. In one UK study, the extreme bass frequencies instilled strange feelings at a concert hall. Effects were "extreme sense of sorrow, coldness, anxiety, and even shivers down the spine."

Piston Heads Rocks! 
In case of Sonic Attack on your district, follow these rules:
If you are making love it is imperative to bring all bodies to orgasm simultaneously.
Do not waste time blocking your ears.
Do not waste time seeking a "sound proofed" shelter.
Try to get as far away from the sonic source as possible
Do not panic
Do not panic
Use your wheels. It is what they are for.
Small babies may be placed inside the special cocoons
and should be left, if possible, in shelters.
Do not attempt to use your own limbs.
If no wheels are available - metal - not organic -
limbs should be employed whenever practical.
Remember:
In the case of sonic attack survival means
"Every man for himself"
Statistically more people survive if they think
only of themselves
Do not attempt to rescue friends, relatives, loved ones
You have only a few seconds to escape
Use those seconds sensibly or you will inevitably die
Think only of yourself
Think only of yourself
Do not panic
Think only of yourself
Think only of yourself
These are the first signs of sonic attack:
You will notice small objects - such as ornaments - oscillating
You will notice vibrations in your diaphragm
You will hear a distand hissing in your ears
You will feel the need to vomit
You will feel dizzy
You will have difficulty focussing
You will need to breathe more rapidly
There will be bleeding from orifices
There will be an ache in the pelvic region
You may be subject to fits of hysterical shouting or even laughter
These are all sign of imminent sonic destruction
Your only protection is flight
If you are less than ten years old
Remain in your shelter and use your cocoon
Remember - you can help no one else
You can help no one else
You can help no one else
Do not panic
Think only of yourself
