An Overview of Automotive Wind Noise and Buffeting Active Control 10-05-04-0030

This also appears in SAE International Journal of Vehicle Dynamics, Stability, and NVH-V130-10EJ

As the wind speed increases, the contribution of wind noise gradually exceeds other noise sources, affecting comfort. First, the classification of automotive wind noise is discussed in detail according to the formation mechanism, sound analogy, and pressure type. Then the wind noise evaluation and development tools are summarized. Finally, the characteristics and control means of vehicle window-induced buffeting noise are discussed. Considering the appearance and field of view, it is currently difficult to control side window buffeting based on passive methods. Therefore, the proposed method of actively controlling the window opening size, actively opening multiple windows, and even releasing an inverse phase sound source based on control logic has a good application prospect.
