Mayan buildings may have operated as sound projectors

(PhysOrg.com) -- A team of archaeologists from Mexico say buildings built by the Maya people could have served as projection systems and amplifiers to deliver sounds over relatively large distances.

The research team, led by archaeologist Francisca Zalaquett from the Universidad Nacional Autnoma de Mxico, discovered that the temples and public squares in the Mayan city of Palenque, near Ciudad del Carmen in southern Mexico, could clearly project the sounds of a human speaker and musical instruments of the time -- around 600 AD -- across at least a hundred meters, or around the length of a football field.

The research included an archaeoacoustic analysis of public rituals in the plazas of the areas, studying in detail the frequencies produced by musical instruments of the time, white and pink sound emanations, and their reverberations in the plazas.

Zalaquett suggested the buildings would have acted as amplifiers, and their stucco coatings may have been applied specifically to improve the acoustics. Measurements at buildings where some stucco remains suggest it altered the reflection and absorption of the sounds, since this was also demonstrated in the laboratory.

1. Certainly in the ball court at Chichen Itza
And by Kukulkan. The way the steps are set up to reflect sound is just amazing.
