Abstract
The sensor group(s) comprise a group of sensing nodes at a location. The location comprises spatial boundaries. Each of the sensing nodes comprise a sensor area. Each of the sensor group(s) based on: range limits of each of the sensing nodes; shared sensing areas of the sensing nodes; and intersections between the sensor area for each of the sensing nodes and the spatial boundaries. Acoustic signals are captured from an acoustic event via sensing nodes of sensor group(s). Solution(s) are generated by processing the acoustic signals. The solution(s) indicate the location of the acoustic event. A strength of solution compliance value is determined for solution(s). A refined solution is generated employing: sensor contributions of sensing nodes; and the strength of solution compliance value with the spatial boundaries and solution(s). A report comprising the location of the acoustic event is transmitted.
