until today,
apparently it is a mystery, as if the
Temple of Kukulkan does not have enough mystery's about it, for one it is famous for being so precisely constructed that at the
equinoxes, the sun striking one side casts an undulating shadow down the
stairway that closely resembles a snake. In case you didn’t know Kukulkan, the
“Plumed Serpent”, is a serpent deity, photograph Vinicius Kern/Pixabay, back to the 'Chirp', clapping
at the base of the Mayan pyramid causes an echo that closely resembles a bird’s
chirp. Do it repeatedly, or in a group, and the echos will sound like a chorus
of ghostly chirps rolling down the steps of the impressive structures. It’s one
of those tricks tour guides use to impress visitors, but it’s actually no
gimmick,
acoustic experts have been fascinated by the “Chichen Itza Chirp” ever
since it was documented by an acoustic engineer in the late 90’s, but so far no
one has been able to demonstrate if the architects of the pyramid designed it
with the specific echo in mind, or if it was accidental,
Nico
Declercq, an acoustic expert at Ghent University, in Belgium, was one of the
many scientists who ventured to Chichen Itza to study the
mysterious echo. After studying the architecture of Kukulkan’s Pyramid and
performing various calculations and experiments, Declercq and his colleagues
concluded that the architects must have known about the echo produced by the
hollow chamber at the top, but they couldn’t demonstrate that they knew it
sounded like a bird,
the
fascinating thing about this special echo is that it is tied to the sound it
follows. You only get a chirping sound if you clap at the base of the temple.
If you beat a drum or scream, you get a different sound altogether, so it’s
virtually impossible to know if the Mayans knew about the echo a clap would
produce, or if they tweaked the design after its construction in order to get
this specific sound, amazing!
