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.
