适用范围：This International Standard specifies an engineering method for measuring workers’ exposure to noise in aworking environment and calculating the noise exposure level. This International Standard deals withA-weighted levels but is applicable also to C-weighted levels. Three different strategies for measurement arespecified. The method is useful where a determination of noise exposure to engineering grade is required, e.g.for detailed noise exposure studies or epidemiological studies of hearing damage or other adverse effects.The measuring process requires observation and analysis of the noise exposure conditions so that the qualityof the measurements can be controlled. This International Standard provides methods for estimating theuncertainty of the results.This International Standard is not intended for assessment of masking of oral communication or assessmentof infrasound, ultrasound and non-auditory effects of noise. It does not apply to the measurement of the noiseexposure of the ear when hearing protectors are worn.Results of the measurements performed in accordance with this International Standard can provide usefulinformation when defining priorities for noise control measures.
