EVS-EN ISO 17201-3:2019

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.
