The purpose of this International Standard is to provide a computational model to determine the acoustical source level of projectile sound and its one-third-octave-band spectrum expressed as the sound exposure level for nominal midband frequencies from 12,5 Hz to 10 kHz. The standard is aimed for calibres of less than 20 mm, but it may also be applied for large calibres. Additionally, the data can be used to compare sound emission from different types of ammunition used with the same weapon. This standard is meant for weapons used in civil shooting ranges but it may also be applied to military weapons. The computational method can be used as a basis for environmental noise assessment studies. In clause 6 this standard also gives guidance how to use this source level to calculate the sound exposure level at a receiver position. The prediction method applies to outdoor conditions, straight projectile trajectories, and streamlined projectile shapes. Because of the latter, it cannot be applied to pellets. Default values of parameters used in this standard are given for a temperature of 10 °C, 80 % relative humidity, and a pressure of 1013 hPa. Annex A can be used for calculations in other atmospheric conditions. Especially for calibres < 20 mm the spectrum is dominated by high frequency components. As air absorption is rather high for these frequency components, calculations are performed in one-third-octave-bands to get a more accurate result for air absorption.
