ISO 13474:2009 specifies the framework of an engineering method for calculating a statistical distribution of sound exposure levels for impulsive sound events for the purposes of environmental noise assessment. It is applicable to impulse sounds propagating over large distances (e.g. 0,5 km to 30 km) from sources, such as mine blasting, artillery fire and bomb explosions, using conventional explosives of moderate charge mass (e.g. 0,05 kg to 1 000 kg of TNT equivalent). The effects of meteorological conditions and terrain upon sound propagation are considered. Acoustics ST 0 0 0 0 AIISH AIISH 2020-06-23 0 ST035 2020-06-23 00:00:00 2020-06-23 ST
