Brazilian sound designer Diego Silva has developed an acoustic preservation system for Peru's Chan Chan archaeological site. His "Echoes of the Ancients" installation uses directional speakers to recreate pre-Columbian ceremonial sounds within the adobe ruins without causing physical damage.

Silva's team spent two years analyzing ceramic resonators found at the site, digitizing their vibrational frequencies to generate authentic soundscapes. Visitors wear bone-conduction headsets that transmit audio through skull vibrations, preserving acoustic integrity while providing multilingual historical narratives.

The system's adaptive algorithm adjusts sound intensity based on environmental noise levels, ensuring clarity during peak tourist hours. Silva's work has revolutionized heritage preservation techniques, with UNESCO recommending his methodology for fragile sites in Petra and Angkor Wat.

"True preservation means keeping stories alive through all senses," Silva stated. His installation has reduced visitor-generated noise pollution by 70%, earning the site a spot on the World Monuments Fund's Watch List.
