DESCRIPTION
CSN EN ISO 17201-3
CSN EN ISO 17201-3 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 17201-1 or calculated using values from ISO 17201-2. This document applies to weapons with calibres of less than 20 mm or explosive charges of less than 50 g TNT equivalent, at distances where peak pressures, including the contribution from projectile sound, are less than 1 kPa (154 dB). NOTE National or other regulations, which could be more stringent, can apply. Original English text of CSN EN Standard. The price of the Standard included all amendments and correcturs.
