Noise Reduction in a Factory Workplace Using Ray Tracing Method: A Complete Study From Prediction to Experimental Validation
Résumé
Cette étude a pour but de tester l'efficacité et la précision de la méthode des rayons appliquées à l'acoustique prévisionnelle dans les locaux industriels. L'originalité de ce travail consiste en une validation complète de la méthode sur un cas concret et non sur un cas de laboratoire. Le principal résultat est la bonne précision de la méthode des rayons pour prédire des réductions du bruit réalistes par un ensemble déterminé de traitements acoustiques dans un véritable bâtiment industriel, même si le modèle n'inclut pas les effets de diffraction des ondes acoustiques. Enfin, on a montré que la méthode est un outil fort utile pour un industriel afin de choisir une solution de traitement acoustique et d'optimiser le rapport réduction/coût.
