Acoustic Analysis of Small Arms Fire

Abstract

This report presents the results of a study of the spectral content of small arms fire at varying distances. These data can be used in the design of noise mitigating structures for small arms ranges. The one-third octave spectra of both the bow wave and muzzle blast, for distances ranging from 162 to 577 m from the source are presented. The data are then used to develop a model that predicts the relative levels of the two components over much larger distances. This leads to the finding that, along the line where the bow wave is maximum, the bow wave predominates over the muzzle blast by a few dB for distances as large as 10 km. In other directions, the muzzle blast predominates.
