@sur_27In the 1920s, this aircraft listener operated an early acoustic detection system. The device used scoop-shaped reflectors to funnel engine noise through large listening tubes, allowing operators to pinpoint the direction of approaching planes long before radar was developed.

A young man in a dark blue jacket and gray trousers stands beside a large, weathered metal apparatus mounted on a tripod in an open, arid landscape. He grips one of the tripod legs with his right hand while looking directly at the camera, his body partially obscured by the bulky equipment. The device features two large, dish-shaped reflectors, one on each end of a horizontal pipe assembly, with visible wear and faded markings on the metal surfaces. The background shows a dry, flat plain stretching toward low hills under a bright blue sky with scattered clouds. The overall style is a vintage color photograph with a documentary, historical feel.
