Abstract
A method for identifying a gunshot occurrence. According to one embodiment, microphone data and inertial motion data are acquired with a hand-held device. Based on an acoustic criterion, a determination is made as to whether a gunshot has been produced. Based on a correlation criterion applied to the inertial motion data, a determination is made as to whether the gunshot was produced from fire produced by a first person having physical possession of the hand-held device or by a second person spaced away from the first person.
