Vehicle Wind Buffeting Noise Reduction via Window Openings Optimization

Vehicle wind buffeting noise occurs when one window of a vehicle is opened in a certain way during driving. By optimizing window openings, the buffeting noise can be significantly reduced or may be even eliminated. In addition, the optimized window openings will also provide sufficient fresh air circulation while allows the driver still be able to enjoy listening to radio. This paper provides such an optimization and describes the principle with the results from both laser imaging and road tests.
