Title A comprehensive strategy for the assessment of noise exposure and risk of hearing impairment
Bibliographic information Aug. 1997, Vol.41, No.4, p.467-484. Illus. 27 ref.
Abstract A comprehensive strategy is presented for the evaluation of daily noise exposure level and the assessment of risk of hearing impairment. The risk is defined as the probability for a worker with a given noise exposure history of developing hearing deficit above a given threshold. The strategy uses the concepts of homogeneous groups of exposure and stationarity interval, defined as the period over which the exposure distribution is the same for the members of the group. The number of workers to sample, the number of samples to take for each worker and their duration are discussed. Semi-random sampling is recommended, excluding periods with low noise exposure. Formulae are presented to estimate the daily noise exposure level, its standard error and the corresponding risk of hearing impairment. Topics: exposure evaluation; hazard evaluation; hearing loss; length of exposure; noise level measurement; noise level; prediction.
