Fig. 6From: Microphone array power ratio for quality assessment of reverberated speechThe proposed DRR estimate vs. T 60. The proposed PR-DRR (19) [dB] (solid circled line) DRR estimator (temporally averaged), with the true DRR [dB] (dashed line), versus the reverberation time T 60, for off-main lobe experiment (source-receiver angle is varied from −30° to +30°, and the source-microphone distance is fixed at 2 m)Back to article page
