Outdoor Acoustics: Range Estimation Of Gunfire Over An Acoustically Soft Impedance Ground In A Homogeneous Atmosphere

Abstract: Predicting outdoor sound propagation in uncertain conditions remains a challenge. This increases the complexity of the inverse problem, e.g. parameter recovery in the presence of a particular sound source such as like gunfire. This paper investigates the use of maximum likelihood methods, both frequentist and Bayesian, in inverting true parameters from measured and simulated data. A simple source-receiver acoustic model is used which assumes; a homogeneous atmosphere, soft impedance ground and some medium rang… Show more

“…A large portion of energy output of a firearm exists in the infrasonic frequency range. As highlighted in recent works [6], there is strong evidence to suggest that combining octave windows between in the low and infrasonic, frequency range will greatly improve parameter inference for firearms. Usual techniques try to use information from the supersonic projectile (bullet) which is good for 3D problems (location via miss angle), but may not actually be the best method.…”

“…More recent work by J. A. Parry et al used a simple excess attenuation model, with and without a priori knowledge to infer the source range and simulated data for sound propagation from a blank firing pistol [6]. The ground in this instance was assumed to be vegetative, creating an acoustically softer ground.…”
