Directional Aspects of Forensic Gunshot Recordings
Robert C. Maher, Steven R. Shaw · 2010
[email protected] Crime scene forensic evidence may include audio gunshot recordings obtained from some known or assumed location with respect to the shooting position. The acoustic evidence of the gunshot depends significantly upon the relative orientation of the firearm's barrel and the recording microphone due to the inherent directional characteristics of the gun, the microphone, and the acoustical characteristics of the surrounding environment. This paper describes an experiment involving the directional characteristics of several types of firearms.
