German researchers have developed a drone capable of detecting human cries. This system could assist rescue operations to locate victims trapped under rubble.
Drones have become indispensable for the operations of, allowing you to quickly monitor the terrain from the . Some are even equipped with to be able to detect the issued by victims. Researchers from have developed a new approach to identify the cries of people in distress.
Theis equipped with a set of microphones, distributed in such a way as to be able to use to determine the direction of the sound. They are the same type as those for smartphones and hearing aids, in order to limit the size and weight of the equipment. Researchers also plan to add a microphone with a wider sound. This will improve the detection and classification of sounds, and will capture noises several hundred meters away.

An AI to identify the sounds of victims
Researchers checked in by calling for help and tapping on objects like someone trapped under rubble might. Theuses artificial intelligence, trained with these recordings, to distinguish screams and other noises from people in distress. The AI also filters out ambient sounds, including the roar of its own engines.
In an interview with, the researchers indicated that they do not intend to commercialize this themselves, but have already been addressed by several organizations that would be interested in a partnership.
