| Abstract(in English) | This paper describes the simulation of sound propagation in a one dimensional medium. If the medium is filled by a sound absorptive material, it is hard to get the analytical solution. The simulation is considered to be useful in such the case. This paper uses the Bergeron simulation method which is used widely in the simulation of a sound field and an electro-magnetic field. But this method cannot be directly applied to the propagation in a medium with transmission loss. So, this paper tries to apply the Bergeron method to LCRG ladder circuit. Some difficulties are found in our investigation. |
