Factory-noise prediction models are invaluable in allowing worker noise-exposure levels in a factory to be evaluated prior to construction and, if necessary, for modifications to be made or noise-control measures to be evaluated. Ray- tracing techniques have proven to have the necessary accuracy and flexibility. In order to evaluate the accuracy of a ray-tracing model, comparisons were made between predicted and measured sound pressure levels for a machine shop with nine noise sources in operation. The shop was modeled using the known geometry, source and receiver positions, air absorption coefficients, and the measured source sound power levels. Surface absorption coefficients were chosen on the basis of reverberation time measurements in ...
