In the little more than two years that the Springfield, MA, Police Department has employed ShotSpotter acoustic technology to detect gunfire, the system has alerted police to more than 4,100 instances where a weapon has been fired. The system covers three of the city's 32 square miles and is designed to locate the scene of gunfire through a process called "acoustic triangulation."
Other sounds (including fireworks, loud motorcycles, tractor trailers, and backfiring automobiles) also trigger the system, which has dramatically decreased the response time of police responding to gunfire incidents.
