Aztec Death Whistles Sound like Human Screams and May Have Been Used as Psychological Warfare

(Read the article on one page)

When odd, skull-shaped grave items were found by archaeologists decades ago at an Aztec temple in Mexico, they were assumed to be mere toys or ornaments, and were catalogued and stored in warehouses. However, years later, experts discovered they were creepy ‘death whistles’ that made piercing noises resembling a human scream, which the ancient Aztecs may have used during ceremonies, sacrifices, or during battles to strike fear into their enemies.

Quijas Yxayotl , a musician who plays an array of traditional Mexican Indian Civilizations instruments, demonstrates an Aztec death whistle.

Two skull-shaped, hollow whistles were found 20 years ago at the temple of the wind god Ehecatl, in the hands of a sacrificed male skeleton. When the whistles were finally blown, the sounds created were described as terrifying. The whistles make the sounds of “humans howling in pain, spooky gusts of whistling wind or the ‘scream of a thousand corpses” writes MailOnline.

Roberto Velázquez Cabrera, a mechanical engineer and founder of the Mexico-based Instituto Virtual de Investigación Tlapitzcalzin, has spent years recreating the instruments of the pre-Columbians to examine the sounds they make. He writes in MexicoLore that the death whistle in particular was not a common instrument, and was possibly reserved for sacrifices – blown just before a victim was killed in order to guide souls to the afterlife- or for use in battle.

 “Some historians believe that the Aztecs used to sound the death whistle in order to help the deceased journey into the underworld. Tribes are said to have used the terrifying sounds as psychological warfare, to frighten enemies at the start of battle,” explains Oddity Central . If the whistle was used during battles, the psychological effect on an enemy of a hundred death whistles screaming in unison might have been great, unhinging and undermining their resolve.

Other types of ancient noisemakers have been found made from different materials, such as feathers, sugar cane, clay, and frog skin.

Los Angeles Times reports that some experts think the ancients used the different tones to send the brain into certain states of consciousness, or even to manage or treat illnesses. Some of the replica whistles created by Cabrera make sounds and tones reaching the top range of human hearing, almost inaudible to us.

An expert in pre-Hispanic music archaeology, Arnd Adje Both told Los Angeles Times "My experience is that at least some pre-Hispanic sounds are more destructive than positive, others are highly trance-evocative. Surely, sounds were used in all kind of cults, such as sacrificial ones, but also in healing ceremonies.”

Roberto Velázquez Cabrera notes that although pre-Columbian music has been lost to us in modern times, the sounds of recreated whistles can be used to give us a better understanding of the ancients. He said, “We've been looking at our ancient culture as if they were deaf and mute. But I think all of this is tied closely to what they did, how they thought.”

Hearing hundreds of death whistles would have induced a painful terror on the enemy, especially if they have never heard such a thing. Putting myself in ancient shoes, I would have probably thought it was magic or something never to be messed with. I am going to look for more research on trance-evoking sounds and whistles.

I want one as a hood ornament. Imagine the sound at 60 mph!!

ROFL...count me in on one....Well, how about a dozen on one vehicle. Mu.hahaha!

I see a whole new cottage indusrty. Halloween will never be the same!

The Highland Scots know the value of screaming cats in warfare too.

Could you elaborate on this statement, please? I find it incredibly interesting.

i think hes referring to the use of bagpipes, whose sound has been likened to that of strangled cats

I think these death whistles were used during sacrfices and in battle.  Can you imagine the shear terror they'd create in the mnds of the faithful and the foe?  Psychological warfare at its finest I suspect.  Nothing like using fear to control people OR preparing the enemies mind for defeat.  Works every time!


can sound like a Very angry falcon.

That sounds like a woman being murdered. I couldn't even imagine hundreds of those coming at me all at once... I had nightmares about just that however when I was very young. Passed it off as just silly fears that accompanied being young, but as I got older I realized that that stuff did exist. I think thats gotta be the most terrifying part of this whole thing.

Our Mission

Ancient Origins seeks to uncover, what we believe, is one of the most important pieces of knowledge we can acquire as human beings – our beginnings.

While many believe that we already hold such knowledge, our view is that there still exists a multitude of anomalies and mysteries in humanity's past that deserve further examination.

We therefore wish to foster an open community that is dedicated to investigating, understanding and explaining the origins of our species on planet earth. To this end, we aim to organize, support and even finance efforts in this direction.

Our aim is to move beyond theories and to present a thorough examination of current research and evidence and to offer alternative viewpoints and explanations to those currently held by mainstream science and archaeology.

Come with us on a journey to explore lost civilisations, sacred writings, ancient places, unexplained artefacts and scientific mysteries while we seek to reconstruct and retell the story of our beginnings.
