Research progress of workplace noise measurement standards
In this paper,a systematic review method was used to compare and analyze the noise exposure measurement standards or technical specifications of 12 countries or standardization organizations from six aspects,including work analysis,measurement strategies and individual measurement requirements,evaluation indicators,instrument calibration and uncertainty analysis.The results showed that 7 countries required to identify the type of occupational noise before measurement,and 4 countries defined similar exposure groups in work analysis;10 countries have specific requirements for the placement of the microphone for individual noise meters;LAeq is the main evaluation index of continuous noise,and most countries adopt Lpeak C weighting or A weighting to evaluate the pulse noise level;in addition to the acoustic calibration before measurement,four countries such as Australia also require calibration after the measurement and stipulate calibration deviation.
