Remove the MythBusters and Brainiac sections

Considering that these shows only tested a handful of notes, and not a spectrum, they should not be included as a "disproof".

All of the examples have only mentioned specific notes, and therefore, present an unfair biased POV.

Brainiac

This was also tried in the show 'Brainiac', apparently successfully [[1]]

The show asked for feedback from viewers as they had transmitted the note on the programme (after appropriate warnings.. I chickened out and turned the sound down!). Unfortunately I never heard what happened.

Well, given the "scientific quality" of Brainiac, I wouldn't believe them a second. Besides, I didn't chicken out and nothing happened to me. Which may very well due to the nature of the tone broadcasted, because it was quite audible (and thus not < 20 Hz). If it did anything for any viewers, probably only through suggestion. And both the speaker they "used" and any given TV set are definitely not capable of reproducing said frequencies.

Having seen that particular episode of Brainiac, I can say that nothing happened and the sound being broadcast was audible. Manufacturing a TV to produce sounds which people can't hear is pointless outside of the scientific community (if at all). Willard 00:19, 29 July 2005 (UTC)[reply]

Well, not exactly pointless, but if you want to control the masses, like in 'You shall go to the toilet in 5 seconds', there is a point in that, if you catch my drift :P not really a good point, but a point nevertheless. It's exactly like those lame TV shows wich had a contest with little stickers you were supposed to attach to the TV screen for the duration of the show, in a certain corner, over a red star or smth. They say that the photo cell inside the sticker will retain the 'special signal' transmitted. If they could do that, we'd all be zombies by now, slaves of TV ads! Well, anyway, have fun and may TV never be able to do such a thing! I'm off to buy that ninja sword with a dragon on the blade. :P Kerfax (talk) 20:40, 16 June 2008 (UTC)[reply]

Brown Noise is unrelated

Somebody put a couple parenthetical also known as "Brown Noise". Brown Noise has nothing to do with the mythical brown note, brown noise is a kind of noise with a precisely defined frequency power spectrum--nothing to do with this silly urban legend. --Brentt 05:00, 13 January 2006 (UTC)[reply]

They might have gotten that from the South Park episode in which a note with this effect is called the "Brown Noise". Timrem 23:04, 4 September 2006 (UTC)[reply]

Phase effects

"In addition, the strategy of surrounding the subjectlo with speakers without accounting for phase effects would have resulted in a loss of effective power being transmitted, especially at the geometrical centre of the speakers."

Certainly, with four speakers surrounding someone, unwanted interference effects would occur; but surely at the 'geometrical centre' all 4 sources would be in phase and thus interfere constructively? (on the not unreasonable assumption that the signal is transmitted to all 4 speakers in phase).
I've removed the clause after the comma in the second sentence as that seems to make it more accurate; but I could just be missing something. Please correct me if this is indeed the case.

To be honest, due to the long wavelength of sounds at these frequencies, the intensity of the sound inside the ring of speakers should never reach a minimum at any point within this ring at all (unless the speakers were placed more than about 30m apart); this would seem to make interference effects rather neglegible.

Related issues

We know that cetain levels of low frequencies can cause lung collapse (trying to get the ref.) But has anyone heard of exposure to very loud (>100 dBA) bass frequencies cuasing heart palpitations? I had a case of this last weekend and I think it may be to do with the fantastically high levels of bass in the room.--Light current 14:50, 28 September 2006 (UTC)[reply]

If you're prone to them, probably lots of things will trigger them. — Omegatron 15:38, 28 September 2006 (UTC)[reply]

YEs I ve been told stress can trigger them also. I was stressed by all the bloody loud bass! 8-)--Light current 15:42, 28 September 2006 (UTC)[reply]

Happens to me, too. :-/ — Omegatron 17:10, 28 September 2006 (UTC)[reply]

Yes, well, I found it to be somewhat true. I don't know about the so-called 'Brown Noise', but I do know that standing close to a source of loud bass sounds will cause some problems. For example, I was standing at a concert a few years ago (don't remember wich one), right in front of the subwoofer (or whatever). I should probably mention that the thing was as tall as me. All I remember from the concert is that I was really sick, I almost couldn't hold back from vomiting. However, as I noticed, this was mainly because my throat was vibrating a lot. Not my bowels. An explanation might be this: all abdominal organs are pretty soft, and therefor they absorb some vibration, or in any case, you can't feel it 100% due to the way the nervous system works (see the Vagus Nerve). But if your neck is resonating, that is a different thing. It's like sticking to fingers deep inside, only the feeling you get is constant when facing the mentioned subwoofer. So, although the Brown Noise might not be a real thing, it's certain that lower sounds can make you feel sick. I dunno if it's the sound itself or just that it makes your organs 'bounce' around and 'hit' each other. Kerfax (talk) 18:53, 16 June 2008 (UTC)[reply]

Nikola Tesla created such vibrations (really)

For entertainment, Tesla once convinced his good friend Mark Twain to test out a vibrating platform in his Manhattan lab. Twain took him up on the offer and found it to his liking. When Tesla commanded Twain to come down off the platform Twain refused because he was having a good time. A few minutes later Twain ran from the device. It seems that Tesla had deliberately neglected to tell Twain that the vibration tended to cause diarrhea.

A Small Cut from the End of the Article

"Interestingly, the wavelength of this note is 746 cm (24.5 ft), which is roughly equivalent to the length of the small intestine."

1. Human small intestine varies from 400 to 700 cm 2. Spurious and coincidental 3. Anyone want to keep it? Jpvinall 08:48, 6 December 2006 (UTC)[reply]

Nope. — Omegatron 14:48, 6 December 2006 (UTC)[reply]

Brown

The article currently states that "brown" in "brown note" is a "metonymy for a common color of human feces". What is this assertion based upon? It seems like original research. Hyacinth (talk) 01:22, 1 July 2008 (UTC)[reply]

You are right about that. That phrase was here when I first saw the article. It can certainly go if not supported or supportable. If there was at one time an online source that talked about metonymy regarding the brown note, then it has since disappeared. Instead, a Google search finds only a host of copycat quotes from this article itself. Feel free to tag or take out the parts you think aren't supported.

Remove article brown note altogether

There is absolutely no reason for this article to exist. There is no such thing as a brown note. THe brown Note is an invention of Matt Stone, and Trey Parker, the writer/creators of south park. Not only do they comment on their DVD of the absurdity of people thinking this actually exists, they have been known to comment that the origin of the idea came, when witnessing an overweight high school marching band tuba player shit his pants on the football field and exhaling harshly into the tuba, creating a loud low frequency blast. This was referred to by their class as the Night of the Brown Noise. It's just stupid for anyone anywhere to think this would exist. Especially since the bowels are in no way connected to the inner ear. —Preceding unsigned comment added by 71.9.2.10 (talk • contribs)

Just because you want it it should be gone? How about the Easter bunny article? Or for that matter any article about aliens or UFOs? Did the article mention that it is only because you hear the sound or because something is vibrating at that rate? You sure didn't put any thought into your rant. —Preceding unsigned comment added by 76.185.84.11 (talk) 05:14, 10 January 2011 (UTC)[reply]

Oddly enough, we have a lot of articles on things that were invented by Matt Stone and Trey Parker. Powers ^T 13:14, 19 January 2010 (UTC)[reply]

It actually is an older myth from about the 70s. South Park just popularized it. 98.198.83.12 (talk) 06:51, 26 May 2010 (UTC)[reply]

Thunderscreech

According to this article, the brown note rumor started with the Thunderscreech airplane tests: http://io9.com/358446/set-your-bowel-disruptor-to-explosive-diarrhea Can anyone corroborate? —Preceding unsigned comment added by 98.125.231.83 (talk) 03:02, 29 May 2010 (UTC)[reply]

More on the Thunderscreech here: http://www.airspacemag.com/how-things-work/cit-wilkinson-july03.html?c=y&page=5 more reliable source, says the the noise of the 'screech was blamed for two miscarriages and one seizure. Doesn't mention a crapping of pants, but it seems possible —Preceding unsigned comment added by 98.125.231.83 (talk • contribs)

The one unreliable source (io9) does not somehow make the more reliable source (airspacemag) applicable to this article. The topic of "brown note" is not mentioned at all in the reliable source. No need to add Thunderscreech information to this article if no reliable source exists. Binksternet (talk) 03:45, 29 May 2010 (UTC)[reply]

I would think that would be implied by the fact that I (the submitter) didn't add the reference to the article, and asked for corroboration. Did you have any actual value to add, like further research? —Preceding unsigned comment added by 24.20.242.233 (talk) 03:27, 31 May 2010 (UTC)[reply]

CIA's CREST archive reference

In the event any editor wants to improve the references or search for a more reliable source, linked below is a reference available on the CIAs CREST archive. The link is to a CIA .PDF copy of an article discussing this topic. The article mentions the Kansas City Star as a possible source (exact date unknown). A bit of original research shows the 1968 Kansas City, Missouri riot and that a convention of the International Association of Chiefs of Police, took place during 1967 in Kansas City (source:[2]). The reference article refers to the topic as "the ultimate weapon to end war forever" however, description of its use is that of a riot control agent. I am currently topic banned for weapons so I leave this theoretical riot control device reference which may be useful or useless to other editors hoping to improve this article. The topic starts at the end of the second to last page of the article and continues onto the last page. Norton, Roy “The CIA’s Worldwide Kill Squads,” SAGA Magazine, June 1970.

Wired reference

To improve sourcing in the article, here is a 2000 reference on the subject from Wired: Protesters Panic Over 'Crap Cannon' 72.238.86.168 (talk) 23:56, 20 January 2022 (UTC)[reply]

In the interest of improving referencing in the article Popular mechanics has the following article: So What Is This Secretive Chinese Sonic Weapon Exactly? 72.238.86.168 (talk) 00:17, 21 January 2022 (UTC)[reply]

this is hilarious

just wanna say how funny it is that there are more sections on the talk page of a wikipedia article about a noise that makes people shit than there are on the actual article lmao

Book reference

To improve referencing in this article I put forth for evaluation as a reference on this subject (especially past research), this book: Volcler, Juliette; Extremely Loud: Sound as a Weapon. trans. from French by Carol Volk.
