If you hear gunshots in an urban setting, it's important to get the police to their source as quickly as possible. A new system is being developed to help, by combining autonomous drones with an existing shot-locating technology.
Already in use in over 120 cities in the US, South Africa and the Caribbean, the American ShotSpotter system utilizes a network of microphones within a neighborhood to detect "loud, impulsive sounds."
Whenever such a sound is detected, its geographical originating point can be triangulated by analyzing the millisecond differences in the times at which it was picked up by the different microphones – the closer a mic was to the gun, the earlier it will have detected the sound of that gun firing. That said, a combination of AI software and human staff (at a control center) is used to determine if the sound is indeed gunfire.
