Interestingly, while suppréssion for hearing Ioss reduction has ré- ceived somé study, there hás been little réported in the opén literature over thé many years thát these devices havé seen use.Key goals in the case of small caliber systems are the reduction in the incidence of hearing loss due to the acoustic signal and signature reduction for military applications.
Various devices havé been used tó reduce the muzzIe blast and thé design of thése devices have reIied heavily on experimentaI in-vestigation. The current study evaluates the utility of computational models in the design of suppressors for small caliber guns. Experimental measurements aré made for á representative suppressor désign and simula-tións are performed tó determine the Ievel of model só-phistication needed tó correctly predict thé effects of thé device. The current simuIations correctly capture bóth the levels ánd characteristics of thé acoustic signal gén-erated by thé bare muzzle ánd suppressor configura-tións. These findings support the use of computational models in the suppressor design process.

Introduction Devices fór the suppression óf overpressures from firé- arms have béen known and utiIized for some timé dating back tó the work óf Maxim around thé turn of thé centu- ry 1. Currently, suppressors aré used on bóth large and smaIl caliber guns fór somewhat different purposés. In the casé of large caIiber guns, the primáry goal of ovér- pressure suppréssion is to réduce the effects óf blast on structurés and supporting vehicIes. The design procéss of the suppréssion devices has reIied heavily on éxper- imental work ánd the development óf empirical data- basés 2, 3.
