Reverberation time and audibility in phased geometrical acoustics using plane or spherical wave reflection coefficients
Room acoustics parameters are typically predicted using some form of geometrical acoustics for large rooms. For smaller rooms, phased geometrical acoustics improves results for lower frequencies. The use of a spherical wave reflection coefficient improves the results further, yet the exact impact on...
