Noise propagation in cellular urban and industrial spaces Available to Purchase

The effect of multiple barriers on the propagation of noise in urban and industrial environments is described by a cell model. The cell boundaries are formed by walls, machinery, etc., and each cell contains noise sources. The noise field both within and outside the souce region is discussed. A comparison with the results of previous investigations shows that the cell model correctly predicts the residual background level in traffic‐free zones in urban areas.
