Computer Prediction of Insertion Loss Due to a Single Barrier in a Non-Diffuse Empty Space

One approach to reducing the noise exposure of workers in an industrial environment is to use acoustic barriers around speci c machinery.Therefore computer prediction models of sound distribution should be capable of accurately modelling the acoustic pa'fonnance of such barriers.Presented here is a preliminary investigation into the prediction of insertion loss (1L) due to a single barrier in an enclosed non-diffuse space.
