可根据国定全苏标准(OCT20445-75)和工作方法指示确定等效噪声强度L_e(分贝,A)。等效噪声强度乃是一种积分判据,可用以说明作业地点非稳定噪声的特性和确定噪声定额标准,但按照国定全苏标准和各种工作方法指令确定这种等效噪声强度
The equivalent noise intensity L_e (decibel, A) can be determined according to the national standard of QuanZhou (OCT20445-75) and working method instructions. Equivalent noise intensity is an integral criterion that can be used to explain the characteristics of non-stationary noise at the job site and to determine the noise rating standards, but in accordance with the national standard and all kinds of work instructions to determine the equivalent noise intensity
