Reference for the Binaural Multichannel Wiener Filter,In the last chapter, new reference designs for the multichannel Wiener filter were examined for closely spaced microphones of a monarual hearing aid. This raises the question if these directivity based MWF references can be applied in the context of binaural hearing aids. Research on binaural noise reduction exists for some time [69, 70].

Noise Reduction using Multichannel Signal Processing Approaches, combining approaches are investigated, the concepts of delay-and-sum beamforming as well as differential beamforming are introduced [9, 16, 17, 18, 19]. These broad-band signal processing techniques allow to create a directional response in terms of an incident angle dependent sensitivity.

However, differential microphone arrays (and therefore the differential references for the G-MWF) are not ideal regarding noise reduction in the presence of wind.

Compared with a microphone array at a single position, spatially distributed microphones are able to acquire more information about the sound field. The usage of spatially distributed microphones allows to employ combining techniques for
