Abstract / scope
TS 13474:2002 specifies engineering methods to calculate the average sound immission for a distribution of impulse sound events for the purposes of environmental noise assessment. It is applicable to impulse sounds propagating long distances (e.g. 0,5 km to 30 km) from sources such as mining blasting, artillery firing and bomb explosions using conventional explosives of moderate size (e.g. 0,05 kg to 1 000 kg of TNT equivalent mass). Prevailing meteorological conditions and terrain are considered wherever possible.
