The brown noise (a.k.a brownian noise, brown note) is a low frequency infrasound that disrupts the movement of the colon because it sends signals in the same frequency the colon and the bowels use, resulting in making you wanting to go crap immediately or sometimes throw up or atleast fart. I know this all sounds weird, I didn't believe it until I tried it after reading so much about it.
It was used in China during the early 20th century as a punishing tool where they put it for long periods of times on large speakers connected to amplifiers and make the prisoners literally crap themselves.
It's called brown noise not for the color of the cause, it's because it was found by Robert Brown. It was also used in the United States several times to stop protests, especially in Miami.
I have attached the video of the actual Brown Noise, they say it works on 7 out of 10 people. No harm trying it out.
