Speaker dominance weights and mixing example. Speaker dominance weights (middle) in case of a car driving at 160 km/h. Four passengers speaking one after another each with an SNR=5 dB. The front right window is slightly opened. The spectrograms of the resulting noise-reduced (β=-10 dB) signal after hard switching between active channels (top) and of the combined signal after DSC (bottom) are shown.
