Abstract:The directionality of an explosion should be accounted for when estimating sound power. Our goal is to estimate the directionality of explosions from measurements on an arc not concentric with the origin of the explosion. To learn how to interpret such data, a test was conducted in a grass-covered field using exploding balloons. The balloons were filled with a stoichiometric mixture of oxy-acetylene and when ignited produced acoustic shock waves. The gas-filled balloons were placed in the ground in preformed “… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
