Roberto Velazquez believes the Aztecs played this mournful wail from the so-called Whistles of Death before they were sacrificed to the gods.

The 66-year-old mechanical engineer has devoted his career to recreating the sounds of his pre-Columbian ancestors, producing hundreds of replicas of whistles, flutes and wind instruments unearthed in Mexico’s ruins.

For years, many archaeologists who uncovered ancient noisemakers dismissed them as toys. Museums relegated them to warehouses. But while most studies and exhibits of ancient cultures focus on how they looked, Velazquez said the noisemakers provide a rare glimpse into how they sounded.

“We’ve been looking at our ancient culture as if they were deaf and mute,” he said. “But I think all of this is tied closely to what they did, how they thought.”
