ON THE RELATIONS OF ACOUSTIC RATIO-REVERBERATION TIME-SPEECH ARTICULATION,EXPERIMENTS AND THEORADICAL CALCULATION
Bag Yu-a · 1981
In the earlier studies on the speech articulation in reverberant sound field in room covered only the relations between the articulation score S and the reverberation time T. The role played by the acoustic ratio R i investigated on a quatitative basis. We have disigned the experiment in a special laboratory to obtain a normolized experimental curve of the articulation vs the product RT. The curve is expressed by a form of efficiency of acoustic ratio-reverbration time KrR as
