UNE-EN ISO 17201-1:2020

This part of ISO 17201 specifies a method to determine the acoustic source energy of the muzzle blastfor calibres of less than 20 mm or explosive charges of less than 50 g TNT equivalent. It is applicable atdistances where peak pressures less than 1 kPa (equivalent to a peak sound pressure level of 154 dB)are observed. The source energy, directivity of the source and their spectral structure determined bythis procedure can be used as input data to sound propagation programmes, enabling prediction ofshooting noise in the neighbourhood of shooting ranges. Additionally, the data can be used to comparesound emission from different types of guns or different types of ammunition used with the same gun.This part of ISO 17201 is applicable to guns used in civil shooting ranges but it can also be applied tomilitary guns. It is not applicable to the assessment of hearing damage or sound levels in the non-linearregion.
