Scientists have recreated the scariest sound in the world by printing an Aztec "death whistle," on a 3D printer, an educational video channel dedicated to performing scientific experiments, the Action Lab reported.
According to the media, the Aztec "death whistle," found by archeologists over 20 years ago in Mexico, was presumably used by the ancient tribes in human sacrifice to honor the god of wind, Ehecatl. This assumption was based on the fact that the skeleton holding the so-called whistle was decapitated.
However, this item could have been also used during ceremonies or to intimidate or distract enemies during wars. The reason why the whistle sounds like a human scream is that its internal structure resembles the larynx, the media said.
At least four whistles were printed, each with a multi-frequency sound. They all have quite unique sounds. The smallest, for example, is the only one that sounds like a woman's scream, the media revealed.
As for other archeological discoveries, in early September, Peruvian and Japanese archeologists have uncovered a pre-Hispanic site dedicated to an ancestor cult, with burial chambers, human remains and ceramic offerings in the Cajamarca region of northern Peru.
