Reduction of Interior Car Noise By Using Vector Method 785108

The booming noise in passenger cars particularly with four cylinder engine is often caused by exciting forces transmitted from the engine to the body structure through front engine mountings. Vector analysis to investigate the relation between these transmitted forces and the sound pressure in the cabin is introduced, some examples of reducing the booming noise by modification of engine front mountings are shown and the points to be considered in the design of engine mountings are mentioned in the paper.
