Acoustic wave propagation, Attenuation, Automobile manufacture, Noise pollution, Noise attenuationRésumé
La présente étude de cas rapporte les efforts faits pour diminuer considérablement le bruit parvenant à plusieurs maisons en un quartier résidentiel des opérations d’une grande usine de construction automobile. On a commencé par dresser le plan des bruits créés par celle-ci afin d’identifier leurs sources importantes; ensuite on a modélisé la propagation du bruit émanant de ces sources. Des mesures de réduction du bruit ont ensuite été modélisées pour prédire le taux de diminution perçue dans le quartier, qui a été comparé aux niveaux permis par la loi. On a dressé un plan de réduction du bruit et un calendrier de sa mise en oeuvre. L’effet des mesures déjà exécutées a dépassé les espérances.Fichiers supplémentaires
