A vehicle's underbody has various wind noise sources due to the complex flow structure. Acoustic holography using NAH (Near-field Acoustic Holography) is adopted to identify the sources, and to analyze the characteristics of them such as positions, strengths, and contributions to interior sound. Reduction procedure of wind noise from a vehicle's underbody will be investigated.
