Résumé

La recherche présentée est une étude des conceptions pour optimiser les propriétés acoustiques d’un amphithéâtre par méthodes expérimentales et avec les modèles informatiques. Le principal défi pour le groupe d’étudiantes de quatrième année en génie était que la salle n’a pas été encore complètement conçue ou construit. L’objectif secondaire était l’optimisation de l’amphithéâtre en utilisant le logiciel ODEON au stade de la conception, plutôt qu’après que la salle a été construit, comme c’est souvent le cas. Les quatre paramètres du son en considération étaient: le temps de réverbération, le temps de décroissance, la clarté et le STI. Plusieurs expérimentes ont été mené dans un amphithéâtre similaire pour corroborer le modèle en ODEON. Les résultats du présent amphithéâtre conceptuel ont démontré des niveaux de temps de réverbération et temps de décroissance moins que ceux qui seraient idéales pour ce type de salle de classe, mais ils ont aussi indiqué des valeurs de la clarté et de STI au dessus de la moyenne. Les suggestions sont données pour augmenter la performance acoustique des paramètres sous-performants.
