Figure 4From: Geometry descriptors of irregular microphone arrays related to beamforming performanceCentroid offset (in meters) and performance metrics with fixed dispersions, showing error bars at ±1 standard deviation. (a) MLW for a dispersion of 3.5 m. (b) MPSR for a dispersion of 3.5 m. (c) MLW for a dispersion of 0.5 m. (d) MPSR for a dispersion of 0.5 m.Back to article page
