Speech would be radiated with sound system in multipurpose halls, so speech transmission quality would be influenced by the difference of the number/position and of frequency characteristic of loudspeakers. In this study, subjective rating of speech transmission quality called "easiness of speech perception" was measured in simulated sound fields with monaural/binaural systems to find binaural effects. The results suggest binaural simulation is needed. And the relations between subjective rating and several physical indices were examined. As a result, subjective rating would be influenced by frequency characteristic that could not be evaluated with existing indices such as STI.
