How Acoustic Gunshot Detection Works Source: Open Data DC Shotspotter data published by Washington, DC law enforcement. Acoustic gunshot detection relies on a series of sensors, often placed on lamp posts or buildings. If there is a loud noise, the sensors detect it, and the system attempts to determine whether the noise matches the specific acoustic signature of a gunshot.
