The Potential for Mitigation of Gun Blast Noise through Sheltering of the Source
Abstract
Community reaction to noise from guns of various sizes is a continuing problem for Army training facilities. While the higher-frequency components of gun noise are substantially attenuated by the atmosphere, the low frequency components are often strong enough to cause annoyance or alarm in the surrounding community. It is desirable for training range managers to mitigate noise as much as possible at the source to avoid violating local noise regulations and risking the loss of training capacity. It has been suggested that a community in a specific direction from a firing point could be shielded significantly from gun noise by an acoustic shelter erected in the immediate vicinity of the gun. This report includes the results of mathematical analyses for two idealized shelter models-one designed to mitigate artillery and tank blast noise, the other to mitigate rifle fire noise. The results suggest that acoustic sheltering of this sort probably would not effectively shield a community from the noise of large guns but may work effectively to mitigate rifle noise.
