Abstract:

A theoretical approximation is obtained for calculating the acoustics of a finite multilayered anisotropic cylinder which is excited either by a mechanical force or by a plane wave at oblique incidence. The cylinder dynamics is obtained by a semi-analytical theory, and the far field acoustics by standard cylindrical baffle theory. A numerical example of steady state and transient sound radiation demonstrates an application of the model. Sound radiation. Sound scattering. Anisotropic layered cylinder. Simple supports
