English abstract:
This paper presents a comparison of a finite element method (FEM) Fluid Structure Interaction Model and an analytic solution of the sound pressure field in two neighboring, coupled and rectangular rooms with different source locations at the low frequency sound spectrum. The FEM Model described in the paper combines the pressure acoustics of a linear elastic fluid in the air volumes and of structural mechanics to connect the acoustics pressure variations in the fluid domain with the structural deformation in a the partition wall. A parametric study and comparison between both models is shown which has different source positions, room dimensions, wall properties and the mesh density of the FEM model as parameters. It is shown that the solutions of the FEM Model fit in the dependence of the mesh density to the described analytic solution of the physical problem.
