How to Predict Factory Sound Propagation

The acoustic's group of the University of Sherbrooke is currently undertaking .research on the prediction of factory noise.A reliable factory noise predice tion method is a valuable tool.It allows the estimation of worker noise exposure levels and should be an integral part of any prevention programme.It allows noise level to be predicted in, for example, the following cases: for new installations, to optimize the building design; for different equipment layouts, so that the layout can be optimised; without and with noise control measures, to evaluate their effectiveness.Accurate prediction requires two things: a comprehensive accurate predictive modeh accurate values for the prediction parameters.This paper discusses current research aimed at developing and validating pred iction models and determining the relevant parameters.
