abstract = "In this paper, 3 types of coherence analysis are performed for a wind-induced noise using a 2-channel small microphone array. The results indicated that there were the linear correlations in the low-frequency band when the microphone spacing was very close each other and the propagation
speed of the wind-induced noise is not the speed of sound but the speed of wind. These results could lead to the wind-induced noise reduction by a linear signal processing with the transfer functions considering the speed of wind. Applying the beamforming technique to the wind-induced noise,
Signal to Noise Ratio (SNR) was improved about 4-10 dB.",
