| Abstract | We evaluate the accuracy of direct-to-reverberation energy ratio (DRR) estimation that uses the direct sound to reverberation spatial correlation matrix model (DRSC model). The DRSC model, which expresses the spatial correlation matrix with two different matrices of direct sound and reverberation, assumes that the direct sound propagates only from the direction of the sound source but that the reverberation arrives from every direction uniformly. The DRR is calculated from the power spectra of both the direct sound and reverberation that are estimated from the spatial correlation matrix of the observed signal. The method was evaluated using various scales in both simulated and actual acoustical environments. The evaluation results confirmed the effectiveness of DRR estimation using the DRSC model and also revealed its limitations. |
