标准范围

ISO 13474:2009规定了工程方法的框架，用于计算环境噪声评估中脉冲声事件的声暴露水平的统计分布。它适用于使用中等装药质量的常规炸药（如0.05 kg至1000 kg TNT当量）从源（如矿山爆破、火炮射击和炸弹爆炸）传播远距离（如0.5 km至30 km）的脉冲声音。考虑了气象条件和地形对声传播的影响。

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.
