Résumé

Les paramètres de définition, D50, et le temps de réverbération, RT, ont été utilisés dans cette étude pour évaluer la qualité acoustique des salles de classe qui avaient été rénovées. Les paramètres D50 et RT ont été mesurés par la méthode de la réponse impulsionnelle.L'analyse de RT dans les salles de classe après leur rénovation montre que ce paramètre a augmenté.L'analyse des valeurs mesurées de D50 a conduit à la conclusion que, malgré l'augmentation de la RT, de nombreux points à l'intérieur des classes affichées bonne qualité acoustique.Cette découverte suggère que les évaluations de la qualité acoustique des salles de classe devraient impliquer non seulement l'analyse de RT, mais aussi du paramètre de la définition, D50.
