A structural FE model for body-in-white of an SRV, an acoustic cavity BE model and an FE-BE coupled model are built. Based on the analysis of the acoustic pressure response at the field points, the peak values of acoustic pressure are found by panel contribution analysis. Based on modes modification method, the acoustic pressure is found and reduced by optimizing the velocity of the nodal point in main vibrant area.
