Convention Paper

Determining the Muzzle Blast Duration and Acoustical Energy of Quasi-Anechoic Gunshot Recordings

Authors: Routh, Tushar; Maher, Rob

AES Convention 141 · Paper 9635 · September 2016

Abstract

Investigation of gunshot waveforms largely includes analyzing the muzzle blast. Generated by the combustion of gunpowder immediately after firing, these brief duration directional shock waves travel outward in all directions at the speed of sound. Features of these waveforms are analyzed to identify characteristics of a particular shot, for example, the combination of firearm type, ammunition, and orientation. This paper includes measured muzzle blast durations for several common firearms and calculation of the total acoustical energy during the muzzle blast period.
