A statistical model is used to predict the number of miners overexposed to noise. A noise exposure probability is calculated for specific operator categories using information on mine worker population, exposure time, measured noise level of an associated piece of mining equipment, and the equipment duty cycle. In combination with information on equipment populations, the model can be used to rank-order the sources of miner overexposures. Also, by comparing noise levels of treated and untreated equipment, the model can be used to estimate the reduction in the number of overexposed miners and evaluate the impact of the control method. The prediction method has been computerized to facilitate the evaluation and comparison of various noise control treatments. The presentation includes a description of the prediction method and examples of its applications.
