ENSEIGNEMENTS ISSUS DES COMPARAISONS ENTRE LES MESURES D'ABSORPTION EFFECTUÉES EN LABORATOIRE ET IN SITU

Abstract

Une vaste étude expérimentale systématique des différents paramètres gouvernant l'absorption acoustique de matériaux a été engagée et se poursuit suivant trois phases : 1 -Mesure de l' Sabine en salle réverbérante normalisée. 2 -Même méthode de mesure dans un local parallélépipédique. 3 -Comparaisons de ces résultats avec ceux correspondant aux mêmes matériaux montés en plafonds suspendus dans deux salles parallélépipédiques. Il est apparu clairement que le même laboratoire, la même méthode de mesure, et le même mode de pose sont trois critères nécessaires et indissociables pour une comparaison valable de l'efficacité de différents matériaux absorbants. Les premiers résultats ont montré que les coefficients d'absorption des matériaux montés en plafond suspendu, déduits des mesures de durée de réverbération effectuées dans des locaux parallélépipédiques vides, sont pratiquement indépendants de ceux obtenus en salle réverbérante.
