D. Tech. Mechanical Engineering. / The level and quality of vibration experienced by motor vehicle occupants are issues of increasing concern and will probably be among the major challenges of the automotive industry in the twenty-first century. The vibration behaviour of door panels that enclose the passenger cabin can affect low-frequency noise in the cabin. This thesis presents the theory necessary for the development and simulation of a vibroacoustic door mount system and, thereafter, investigates its potential. Compared to the existing design, a perceivable noise reduction of 6.15 dB(A) was achieved by using the proposed sensitivity analysis procedure.
