Abstract
To identify vehicle wind noise sources in aeroacoustic wind tunnel, Beamforming technique is widely used today. In this study, a production car Roewe 350 was set on the turntable at 1:1 aeroacoustic wind tunnel of Shanghai Automotive Wind Tunnel Center (SAWTC), a planar spiral microphone array with 120 channels (1.8m*1.8m) was set out-of-flow to test its exterior wind noise sources. In interior of the vehicle near the left side view mirror triangle and driver's ear position, 2 reference microphones were set to record potential sound source signal. The results demonstrate that Beamforming technique is a practical method for sound source identification. Furthermore, correlation analysis makes it clear, that side view mirror contributes most to vehicle interior noise. Under different yaw angles, exterior noise sources distribution is different, so is the correlation result.
