Abstract

In the following chapter, basic noise reduction techniques for multichannel microphone setups are derived. Since in this work directivity based signal 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.
