Pyramid in Mexico that Produces Strange Sounds of a Strange Bird

A pyramid has always been an exotic thing with an aura of mystery revolving around it. They are monuments that have eras of history associated with it. Their tantalising architectural and engineering marvel attracts tourists from all across the globe. However, the tourists who have been visiting El Castillo pyramid in Mexico have had strange experience. They have been taken aback by the strange chirp of birds and patter of raindrops inside the pyramid.

 

The architectural marvel was constructed several years ago by the name of Chichen Itza. However, recently, acoustic engineer David Lubman in the year 1998 first came across this bird-call effect. This sound frequently resembles the call of the sacred animal, the Mexican quetzal bird. Lubman says, “When the Mesoamericans were first experimenting with building outdoor temples of every shape and size, the only ones that seemed to reward them with the approval of the gods were the temples with the long outdoor staircase, With those temples, a hand clap would be rewarded with the sound that they would recognize as a messenger of the gods: the quetzal.”

 

This eerie sound has been under the microscope of many scientists who have been studying it closely. The construction of the pyramid has a huge hand as to why this sound occurs. The height and space of the pyramid’s staircase structure creates something like an acoustic filter. This filter exaggerates certain sounds while suppressing others. Echo also plays a part in this structure by influencing the mix of frequencies inside the pyramid. Many speculate that this acoustic quality of the limestone structure was used in advantage of many performances like dance, speech, music, etc. A proper conclusion can be obtained only once inscriptions can be found supporting this statement. It is a thing of beauty combined with mystery; one can only get the feeling when they visit the pyramid in Mexico.
