Audiometry in Industry

Much can be done to reduce the risk of occupational hearing loss by reduction of noise levels, either directly or by means of individual ear protection. A minority of susceptible individuals is likely to remain at risk, however, and there is no certain way of identifying these persons in advance. At the same time the routine administration of audiometry on a periodic basis for the whole workforce of industry, which would be one way of locating these persons, would present formidable problems. To reconcile these considerations a compromise is necessary. In this paper suggestions are put forward indicating which industrial noise exposures merit or demand audiometric monitoring and those for which it may be considered dispensable. Quantitative proposals are given based on the statistical risk of hearing losses from specified noise exposures and some general guidance is offered on the choice of regime for audiometry in different circumstances.
