This is ‘the most terrifying sound in the world’ — hear the Aztec Death Whistle

For those who want to celebrate Halloween like it’s 1399: Scientists are sending shivers down the internet’s spine by recreating an ancient “Aztec Death Whistle” that’s said to emit the “most terrifying sound in the world.” The macabre kazoo is detailed in a new video produced by the Action Lab, a group of proud internet nerds who specialize in mind-bending experiments. “The sound that the death whistle makes innately strikes fear into your heart,” intoned presenter James J. Orgill in the clip while holding a 3D-printed version of the instrument. The Brigham Young University engineering grad then plays an audio clip of the scream machine, which evokes a bloodcurdling, banshee-like shriek that evokes a sound effect from a haunted house attraction.
