Prediction des Conditions Sonores dans les Salles de Classe au Moyen des Carateristiques Physiques de l'environnement
Résumé
Une recherche-terrain a été menée dans 50 classes de six écoles primaires de l'île de Montréal dans le but d'identifier des conditions physiques susceptibles de prédire l'intelligibilité de la parole dans les classes. Un modèle empirique fondé sur l'évaluation du rapport signal-bruit en dBA et de la durée de réverbération à 1000 Hz a été utilisé. Trois variables ont été identifiées comme étant prédictives d'une intelligibilité de la parole optimale dans les classes soient l'absence de bruit de ventilation, la fermeture des aires par des cloisons complètes et la présence de tuiles acoustiques au plafond.
