Brown note: bad vibration mega-hurts Most of us find music stimulating. But it has been suggested that one particular type of music can be a little too stimulating. Dr Karl lowers the tone to try and get to the truth. By Karl S. Kruszelnicki <hr class="lineBreakTop" noshade="noshade" size="1"> Is it possible to create infrasound with very large loudspeakers?

You may have heard that elephants can "talk" to each other using an odd high-pitched note. But elephants can also stamp their feet on the ground and "talk" to each other over many kilometers with "infrasound". Infrasound is just a sound that is too low-pitched for our human ears to detect. Whales and dolphins use infrasound to stun, and sometimes kill, their prey. So why should we doubt the popular press when they tell us that the military have fooled around with the technology of infrasound to the extent that they can use it as a non-lethal, and rather stinky, weapon? More specifically, the story runs that they can blast the appropriate frequency and loudness of infrasound at a crowd and make them all instantly incontinent of faeces or, in plain English, "poo their pants". Yes, this is the story of the infamous Brown Note. Indeed, both the Mythbusters and Brainiac TV shows tried to recreate this Brown Note and failed — but they had only a brief production time available to them. On the other hand, the naughty boys in the cartoon series, South Park (episode 317), used the unlikely venue of an international online recorder concert to recreate the Brown Note. They swapped the regular sheet music for ones with the Brown Note, and caused world-wide uncontrollable bowel release — but South Park is animation, not real. Now sound is simply a change in air pressure. Our ears can generally pick up this change only if it happens somewhere between 20-times per second (20 Hertz, or 20Hz), and 20,000 times per second (20,000Hz). This is the so-called "audio band" — and of course, as you get older, you lose the high frequencies. Any sound above 20,000Hz is called "ultrasound" — we humans can't hear it, but bats use ultrasound to avoid obstacles in the dark. Sounds lower than 20Hz are called infrasound — and again, we humans cannot hear it. Natural sources of infrasound include waves crashing on a shore, waterfalls, wind turbulence in mountains, meteors blasting into the atmosphere, volcanic activity and earthquakes. We humans make infrasound with really large organ music pipes, rocket launches and sonic booms — and with very large loudspeakers, sirens, whistles and piezoelectric tranducers. Beginning in the 1960s, the popular press reported exaggerated and anecdotal claims as to how effective infrasound was as a non-lethal weapon against people. In the mid-1990s the press reported the existence of the Squawk Box as a military weapon. It supposedly emitted high-intensity and high-frequency sounds of 16,000Hz and 16,002Hz. These close frequencies then interfered with each other to produce a devastating and incapacitating 2Hz infrasound tone. But it was later admitted that the "weapon" was a hoax, and was just some "disco gear" mounted on armoured personnel carriers. There are known effects of infrasound, depending on how loud the sound is — vibration of the chest wall, changes in respiratory rhythm, sensation of gagging, vibration of the visual fields and so on. It's well known that infrasound of 4–6HZ will make the contents of the chest and abdomen vibrate in sympathy, while 3–6Hz will interfere with the normal motility of the stomach. Infrasound lower than 2Hz will make your whole body move as a single unit<sup class="attribution" title="Reference 1">1</sup> in resonance with the sound. But getting to the hard data, in early 2007, US Air Force scientist Dr James Jauchem and his colleague Dr Michael Cook, reviewed all the peer-reviewed literature in the field of energy bioeffects. They found absolutely no evidence<sup class="attribution" title="Reference 2">2</sup> of infrasound causing diarrhoea. In fact, they concluded that infrasound is very unlikely ever to "provide a device suitable as a non-lethal weapon". So infrasound has not yet been developed into a weapon that will require you to change your underwear. On the other hand, don't underestimate the noxious effects of sound in the regular human audio band. After all, studies have shown that Barry Manilow music is quite effective in repelling teenagers from shopping malls. ^ to top References
All that methane gas at once, while some one is lighting a cigarette, BOOM. There was a methane gas explosion at a demonstration today...
What disturbs me the most about this is the comment board below the article. Did anyone read it? My lord man where has this country gone! I believe in the right of everyone's freedom of speech even if it differs from my own views and beliefs, I still want them to have the right to express them! Were not a free country anymore when only the popular opinion is allowed! This generation (my generation) has been brainwashed by the school system and popular society to not understand what freedom is all about! They think it serves people right who disagree with them to be treated harshly and don't think they should be entitled to their right to express their views. If this is a healthy thing to do then every time you side with the unpopular side of an issue you should just be chastised? What the freak is that! That's not freedom! And the sad part is most of them who think that way are the one's that are asleep sheeple who are wrong and can't see the truth through their government brainwashing! I am truly sad and disgusted that so called fellow Americans would want to restrict the rights of and chastise their fellow American's for holding a different view and utilizing their freedom of speech! "Hey they don't think like us and their talking crazy, we should just put a bullet in their head and be rid of them for all" what the hell is that we should be killed for having a difference of opinion !@#$ freak that pisses me off! This isn't my beloved America anymore!
I play bass and you can hit a few notes on the two big strings to put people in the mood. It will probably create upset stomachs. That's OK, I have a tinfoil suit!
