摘要
在预测列车运行噪声时 ,经常需要根据列车通过时的最大声级Lmax(或列车中部声级Lm)计算等效声级Leq或暴露声级LSE。为解决此问题 ,笔者通过理论分析 ,给出计算等效通过时间的方法。然后用等效通过时间可简单地计算出Leq和LSE。
During the prediction of train running noise, L eq or L SE is often calculated according to the L max or L m when train is passing by. In order to solve this problem, a way is introduced to calculate t eq through theoretical analysis in this paper. Then L eq and L SE can be calculated easily.
