• Abstract There is a large amount of medium and low frequency noise in the interior of a certain vehicle type under constant speed driving conditions. Through identifying the noise source, it is determined that it is mainly caused by road noise. The suspension rubber bushing, mounting inching stiffness, and vehicle body sheet metal are optimized, and the interior noise is reduced by 3 to 5 dB (A).
