Abstract
A system, device and method facilitate accurate detection of gunshot events through spectrum analysis of impulse signals and/or evaluating impulse signal exponential decay amplitude and time values. In various embodiments, the device and system employ an acoustic sensor, one or more high-pass and low-pass filters, a threshold detector, a differentiator, a decay waveform shape generator, one or more comparators and one or more timers to facilitate detection of gunshot events and/or components of gunshot events.
