oh, you're knowledgeable huh? south park isn't a sound engineering school bruh. they might try to sell you on that bullshyt in full sail though
http://en.wikipedia.org/wiki/Brown_note. start there. read the pdf too.
basically what it comes down to is, has anyone demonstrably shown it exists? the answer is no.
The french Police and Tokyo Police have used it on crowd control but not to full extent
the germans tested this on people during WWII
bro I went to Full Sail, my audiotronics teacher was a weirdo but he was intelligent
first person who told me about Nikola Tesla and I researched him on my own
my studio's instructors worked on Thriller all the way to Outkast albums breh
I ain't making this shyt up, one of them was a foreign and he was the one who told the class the french police used it and wrote the exact system you would need to produce it in my notes, but this shyt was years ago and I will have to find it
and Wikipedia is not a good source for anything
especially when average people have been mislead by the so called testing
all not using the power required to produce the sound
and once again SHOW ME THE TEST
SHOW ME THE TEST, I WANT TO SEE THE ACTUALLY PROCESS THEY USE TO TEST AND I WILL TELL WHY IT DIDN'T WORK
