|초록||A vectorial approach is used to reduce the objectionable booming noise in the vehicle interior cabin. After identifying the structural transmisson paths, the structural-acoustic transfer functions are evaluated at those mounting positions. Using the measured deformations in the mounting elements and multiplying them with each dynamic stiffness value one can easily get the dynamic input forces acting on the mounting elements. By summing all the contributors vectorially, most important contributor or transmission path can be determined. According to the experimental information, devised countermeasures are applied to a development car and good results are obtained.
