Abstract: This paper presents the results of the numerical investigation of structure-borne vehicle interior noise in a simplified model of vehicle compartment. The aim of the paper is to analyze the effects of different variations of certain geometrical and material parameters of vehicle structure on structural-acoustic frequency response functions. It has been found that geometrical modifications have little influence on the structural natural frequencies. However, they strongly affect the acoustic natural frequencies and normal modes as well as the resulting sound pressure responses. The increase in thickness of the bottom plate suppresses the sound pressure responses very efficiently. However, variations of material characteristics of wind- and back-screen do not have much influence on the interior noise.
