[交流] 请教声音测量的两个问题

我们要测量的声压级参数是LpA,1s，但使用声压表并没有完全相同的参数，请问这个声压级有其他的表示方法吗？或者，这个参数是不能直接测量，而需要用别的参数计算的？（有如下一段话：As an alternative to SEL, LAeq can be measured and the total measurement time t registered. The single-event emission sound pressure level can then be calculated from SEL = LAeq + 10 lg(t).
The highest value recorded (LpA and LpC peak) at any of the microphone positions is the measurement result. the result is the average of the SEL-levels and the highest of the peak levels. the result is the average of the SEL-levels and the highest of the peak levels.
求教这个SEL-level是什么意思？和LpA,1s是什么关系？
谢谢
