| Abstract: | The quardripole parameters of a lossless tube are deduced according to the theory of plane wave. Applying the theory of acoustic transmission in a tube and the quadripole we deduce the transmission loss of a single expansion chamber with a insert tube. The equivalent quadripole parameters and their applications are explained. The formulae by which the transmission loss of some two-stage expansion chambers with different types of insert tubes is calculated are given. |
