Development of a Muffler for Small Arms Range Noise Mitigation

Abstract

Small arms fire can result in noise complaints from nearby residents. The objective of the project reported herein was to provide a mitigation strategy to reduce small arms noise impact in the neighborhood of Camp Dodge, IA. The selected strategy was a low cost muzzle blast muffler. The U.S. Army Construction Engineering Research Laboratories (USACERL) designed, constructed, and tested several variations of mufflers. The basic design consists of a tube about 0.5 meter (19 inches) in diameter and about 1.9 meters (6 feet) long that is lined with noise absorbent material and has a bore large enough to afford the shooter an unobstructed view of the target. The performance tests showed that the muffler delivers a noise level reduction in the A weighted sound exposure level (ASEL) of 10 to 20 decibels (dB) in most of the noise sensitive regions around Camp Dodge.
