The transmission of normally incident sound waves through a series of similar, equally spaced partitions has been calculated for the cases of infinite partitions and of circular partitions. The transmission characteristics depend on the solution of simultaneous linear difference equations for the velocity potentials. The array of partitions possesses interesting properties as a filter, and to illustrate these the change in intensity levels due to glass partitions is calculated numerically for 1, 2, 5, and 10 partitions. |
