Advanced LiDAR surveys in the dense jungles of the Selva Lacandona have identified a previously unknown Maya city-state designed with extraordinary acoustic precision. The city, dubbed Xayachén, features a central ceremonial core where the temples and plazas are oriented to amplify and carry human speech over several kilometers. Researchers suggest the city functioned as a regional 'broadcast hub' for religious and political announcements.
The mapping revealed subterranean chambers specifically engineered as resonance cavities, which would have hummed at specific frequencies during large-scale drum and flute performances. The complexity of the urban grid, which includes raised causeways connecting 'satellite theaters,' indicates that the Maya utilized advanced knowledge of psychoacoustics to manage their population across a sprawling jungle landscape.
