1.测量仪器 (1)噪声测量使用声级计,声级计应符合国家标准。 (2)声级计和声级校准器每年应送计量单位校准。 (3)声级计使用前后应进行校准。 2.测量的量和读数方法 (1)测量的量①稳定噪声,测量A声级,测量值后应标记dBA,如80dBA。②不稳定噪声,测量等效连续A声级;或测量
1 measuring instruments (1) noise measurement using sound level meter, sound level meter should be consistent with national standards. (2) Sound level meter and sound level calibrator should be sent to the measurement unit calibration. (3) Sound level meter should be calibrated before and after use. 2. Measurement and reading methods (1) the amount of measurement ① stable noise, measuring the A sound level, the measured value should be marked dBA, such as 80dBA. ② unstable noise, measuring equivalent continuous A sound level; or measurement
