Acoustics. Noise from shooting ranges - Estimation of muzzle blast and projectile sound by calculation Ingestion-build-52208 ISO 20766‑12 describes the test1 Scope This part of ISO 17201 specifies methods for estimating the acoustic source data of muzzle blast and explosions and the source data of projectile sound on the basis of non acoustic data for firearms with calibres less than 20 mm and explosions less than 50 g TNT equivalent. This part of ISO 17201 addresses those cases where no source measurements exist or where the data necessary to calculate projectile sound according to ISO 17201 4 are
