Researchers built drone with tiny microphones that can find screaming humans in a natural disaster

Researchers in Germany have developed a drone that can locate humans by their screams. Rather than a terrifying'Terminator'-like scenario, the autonomous devices would be used to assist first responders in rescuing hard-to-find survivors after a natural disaster. The engineers recorded themselves making sounds someone in jeopardy might create, like screams, bangs and claps. Then they trained the drone's AI algorithm to recognize those noises, while filtering out the hum of its rotors and other background noise. A prototype drone has been programmed to recognize'impulsive' noises humans in crisis might make--like screams, claps and kicks--and locate survivors of human disasters.
