Abstract
Three different types of acoustical measures were compared as predictors of speech intelligibility in rooms of varied size and acoustical conditions. These included signal‐to‐noise type measures, the sound transmission index derived from modulation transfer functions, and useful‐to‐detrimental sound ratios obtained from early‐to‐late sound ratios, speech and background levels. The most successful forms of each type of measure were of similar prediction accuracy, but the useful‐to‐detrimental ratios based on a 0.08‐s early time interval were most accurate. Several physical measures, although based on very different calculation procedures, were found to be quite strongly related to each other.
