The feature of the calculation of structure-borne noise is the composition of the sound pressure intensity vectors in harmonics (considering the distance). The composition is made starting with the visible (at the sighting point) variable number of the emitters in the air-volume. The isolines of the sound pressure's distribution for the frequency of the natural vibration in the air volume of the car's interior are given. The isolines in the sighting point are also given. Results of the distribution depends on the geometrical form of the car's interior are discussed. There is the effect of the displacement of the center of gravity relatively to the mobile panel is the hanging door. The influence of this effect to the sound pressure level is investigated. In general used approach and obtained results are satisfactory.
