Weaponized sound may sound like something out of science fiction, but police and military units have been using the technology for years. Long Range Acoustic Devices (LRAD) recently made headlines when the NYPD deployed the non-lethal weapons on Occupy Wall Street protestors last fall. But while devices like LRAD use high frequencies to induce headaches and hearing loss, the legendary “brown note” serves a more embarrassing purpose.
Long considered an urban legend, the so-called “Brown Note” is a frequency thought to cause a loss of bowel-control in the listener. While the note has been featured in episodes of Mythbusters and South Park, Josiah’s ukulele is the first instrument in recorded history capable of reproducing the tone.
