Acoustic Phenomena at Chichen Itza

The only other place I've ever heard this is in Chichen Itza, Mexico.

This is a phenomenon that people don't understand yet and we found

it here at the wall. My theory is this whole thing is a tuning fork.

So here, the sound comes back.

Why it sounds like a bird?

Don't ask me that, because we don't know. But this is really impressive.

Experts from different countries, experts in acoustics have come here to study,

to try to know how this is possible.

They leave the country.

And it works all four sides the same. Used to be, now only two.

The north and the west.

Now please join me to the front of the steps.

When the sound of the clapping touches

the steps according to the speed of the sound,

that frequency,

it will travel in the chamber.

But when it comes out, it will be equal to the sound of a bird.

And we still don't know how to do that or how they do that, and we say we have.

Are you kidding me? That's shocking. The sound of the

temple and the bird is already in computers and sonograms to check the frequencies.

And the two of them, they're equal. This is the ancient basketball.

I've seen this one in the movie Apocalypto. Yes.
