Abstract
In rooms with nonuniform absorption due to different material properties, the spatial properties of the decaying reverberant sound field were found to be time-variant, violating the common assumption of a diffuse sound field. Recently, we proposed a model for the coherence of such a sound field in a rectangular room, using knowledge of the geometry and surface reflection coefficients. In this paper, we describe a coherence-based dereverberation method based on this model. We conduct an evaluation with impulse responses which were generated for rooms with non-uniform absorption, confirming that the model can be applied for speech dereverberation
