The incident was recorded by a doorbell camera and shared on social media, confusing the online users
Many people are curious to find out the origin of this strange sound, and fortunately, some researchers have issued theories about its origin.
That sound is chilling! Just listening gives me goosebumps,' one user commented.
If it were me, I would faint on the spot, the second joked.
This damn sound could break my heart, another replied.
Where did the sound come from? Someone asked.
Can't imagine the scary moment that man experienced, that sound is crazy! Another said.
The sound was supposed to come from an ancient musical instrument of the Aztecs
According to some experts, this sound may have come from a musical instrument called the "Aztec Death Whistle" which was often used in ceremonies 700 ago.
The Aztec Death Whistle is a mysterious musical instrument first discovered in 1999 in an Aztec tomb in Mexico City.
However, the exact purpose of the Aztec Death Whistle remains a mystery.
Some theories say that the Aztec soldiers used this "world's most terrifying sound" to threaten enemies during war. However, experts say that the Aztec Death Whistle was probably used for ceremonies or religious purposes rather than on the battlefield.
Many believed that Aztecs used the skull-shaped whistle as a final etiquette before they were sacrificed in ceremonies honoring the wind god Ehecatl.
15 years later, a scientist discovered the sound, which sounded like a screaming human, and it has since sparked much speculation about the purpose of the ancient weapon.
Music archaeologist Arnd Adje Both conducted CT scans on the original Aztec Death Whistle whistles to examine their inner workings to simulate a similar one.
The resulting sound was softer than expected, resembling atmospheric noise from the wind.
They suggested that the Aztec Death Whistle was likely used ceremonially or religiously due to its deathly design, rather than on the battlefield.
