Modeling of sound propagation in fitted workshops using ray tracing
AM ONDET, J.L. Barbry · The Journal of the Acoustical Society of America · 1989
This article describes the rayscat computer model, for prediction of noise levels in empty or fitted rooms. The model is based on a ray-tracing technique and takes into account both the real geometry of the room and areas with different fittings (furniture, machines, storage, etc.). Experimental results obtained in a test room are presented, demonstrating the influence of the fitting distribution on noise levels. Finally, the experimental results are compared with those obtained by numerical simulation using the rayscat model. Predicted values agree closely with measured ones.
