||Case history: Factory noise prediction using ray tracing - Experimental validation and the effectiveness of noise control measures
||Nov.-Dec. 1989, Vol.33, No.3, p.97-104. Illus. 9 ref.
||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 9 sources in operation. The shop was modelled 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 similar factories when empty. The ray-tracing model proved to give excellent prediction accuracy. The usefulness and flexibility of the ray-tracing approach are demonstrated by predicting the effectiveness of possible noise control measures comprising acoustic screens and suspended absorption.
