Anisotropy of elastic and acoustic properties increases the potential for performance tailoring of multilayered structures including poroelastic materials. An intrinsic part of such a design optimization is to understand the frequency response behaviour of such configurations in general and those including anisotropic porous layers in particular. In this work a plane wave method for anisotropic multilayered structures has been used to study the response sensitivity for anisotropic porous materials as a function of their material coordinate orientation. It is shown that, depending on the frequency range of interest, the sensitivity to the orientation of the anisotropic porous material varies.
