Poroelastic materials are often used as sound and vibration reduction measures in many engineering applications. Their dynamic behaviour is accurately described by the theory of Biot. The Finite Element Method is most commonly used to simulate such materials, however, is only applicable for low-frequency applications due to the associated computational cost. This extended abstract describes the development of a Wave Based Method to efficiently simulate dynamic poroelastic problems for an increased frequency range.
