Prediction des Conditions Sonores dans les Salles de Classe au Moyen des Carateristiques Physiques de l'environnement
AbstractA field study has been conducted in 50 classrooms from 6 primary schools in Montreal in order to identify physical characteristics that would predict speech intelligibility in classrooms. An empirical model founded on the evaluation of the signal-to-noise ratio in dBA and of the reverberation time at 1000 Hz has been used. Three variables have been identified as predictors of an optimal speech intelligibility in classrooms, namely the absence of ventilation noise, the enclosure of the rooms by complete partitions and the presence of acoustic tiles on the ceiling.
