Acoustics. Noise from shooting ranges - Sound propagation calculations Ingestion-build-63114 A preliminary test is madeWhat is this standard about? This document specifies methods of predicting the sound exposure level of shooting sound for a single shot at a given reception point. Guidelines are given to calculate other acoustic indices from the sound exposure level. The prediction is based on the angular source energy distribution of the muzzle blast as defined in ISO 172011 or calculated using values from ISO 172012. This document applies to weapons with calibres
