Acoustics. Framework for calculating a distribution of sound exposure levels for impulsive sound events for the purposes of environmental noise assessment Ingestion-build-159183 and location element1 Scope This International Standard 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. This International Standard 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
