This is a pretty amazing discovery! Sadly due to the conquest and subsequent colonization so much of the Aztec way of life and customs have been lost. The death whistle is a prime example we don’t know what it was for!
Swiss and Norwegian researchers found hearing them activates a variety of higher order centers in our brains
The skull whistle in particular activated the inferior frontal cortex, which deals with elaborate classification processing, and the medial frontal cortex, a region involved with associative processing.
If someone told me that this sound was a Jurassic Park sound effect, I would easily believe it. As it was explained in the article that there is no evidence that these whistles were used in battles, I confess that it was the first thing I imagined about their use
Same with me! Seems to be a burial thing but there’s some ambiguity to that!
