Wind Noise Reduction for a Closely Spaced Microphone Array
In the previous chapters, directivity based references for the generalized multichannel Wiener filter have been discussed. These include the differential beamforming references, which were successfully applied in the context of closely spaced microphone arrangements for hearing aids. However, differential microphone arrays (and therefore the differential references for the G-MWF) are not ideal regarding noise reduction in the presence of wind.
