Transmission Loss of Multiple Panels in a Random Incidence Field

In this paper, the method of predicting the transmission loss of multilayer panels first proposed by Beranek and Work is used and developed to the point where the method can be applied under conditions where sound is incident on the panel from any angle or from many angles simultaneously as in the random incidence field. Doubts expressed recently about the accuracy of the theory are removed, and the method is shown to be a powerful tool for the prediction of transmission loss.
