drone that can spot screams
Investigators in Germany have created a drone that can locate screams. The device could be used to find survivors, for example, after a natural disaster, The Washington Postreports .
The drone was developed by a team of researchers from the German institute Fraunhofer. They recorded themselves shouting, tapping or producing other sounds that someone in need might make. The drone then learned to recognize these sounds using artificial intelligence.

According to one of the researchers, the device is ideal to use after earthquakes, hurricanes or forest fires, for example. The drones can fly over places where rescuers have difficulty getting there. They can then identify where people might be trapped so first responders know where to go.
“Drones can cover a larger area in a shorter time than rescuers or trained dogs. If a building has collapsed, drones can alert and help rescuers. The drones can fly to places they can’t just go,” said one of the researchers.
