| Abstract: | In this article a math model for sound propagation in industrial enclosures is discussed. The model can be applied to an industrial enelosure with any shape, any boundary condition and any obstacles in it. The original purpose of developing this model is only to predict the noise field in power plants, but the results of measurement of sound propagation in power plant workshops indicate that this model has high predication accuracy and can he adanted to various kinds of complicated industrial enclosures. |
