A comparative study of speech intelligibility metrics that take into account sound refections in the room and the background noise has been developed based on the assumption of a d iffuse sound field in the room Under this assumption the room reverberant response results in an exponential decay with a damping constant inversely proportional to the reverberation time. This allows analytical formulas to be obtained for each of the speech intelligibility metrics considered in this study, and provides a common basis for this comparative study. These formulas were applied to three sizes of a rectangular shaped classroom, inside which the sound source was a human voice without amplification. The background noise was taken into account in these fo...
