A new method of prediction for the noise propagation in a city area is proposed. In this method, buildings in a city area are assumed to be randomly distributed. Therefore, the characteristics of the noise propagation are easily given. By using the average height of the buildings and the perspective distance among them, the propagation losses are predicted without solving the wave-equation subject to the complex boundary conditions. In order to examine the results, the random distribution of the buildings is produced by the computer simulation, and the properties of the noise propagation are calculated. In addition, the scale model experiments are made on the distribution of the buildings. From the results of the computer simulation and the model experiments, the prediction method is proved to be appropriate.
