Measurements of Sound Pressure Levels for Aerial Shell Mortar Firings and Star Shell Bursts

K. L. Kosanke and B. J. Kosanke

Abstract: A large number of sound pressure level (SPL) measurements were recorded for the firing and bursting of firework star shells ranging in size from 3 to 6 inch (75 to 150 mm). The results of a series of 400 measurements of SPLs of firework aerial shell mortar firings as a function of distance from the mortars are reported. Also, the results of a series of 200 measurements of SPLs of firework star shell explosions occurring at their normal burst heights are reported.
