| Abstract(in English) | In this report, wind-induced noise reduction in time domain was investigated using closely-aligned two microphones. A linear beamforming filter in frequency domain on the basis of time frame decomposition was applied to signals in time domain. The beamforming filter's ability of reduction for wind-induced noise was compared between with and without the time frame decomposition. As a result of performing the wind-induced noise reduction, the signal-to-noise ratio was improved by about 2 to 13 dB, for recorded signals disturbed by wind-induced noise. In case of that the filter composed of some simple delay units was employed, the time frame decomposition was very influential to the ability of reduction for wind-induced noise. |
