Acoustic Design of an Innovative Sound Package for Heavy-duty Cabin for Future Generation European Trucks 2007-01-4227
An innovative methodological approach for the virtual design of heavy-duty truck cabin acoustic packages is described together with its application to a truck model forecasted in 2008. A properly tailored version of Statistical Energy Analysis numerical approach to truck cabin peculiarities has been defined, with a special focus on aerodynamic noise investigation, being one of the most relevant noise sources in a truck cabin running on highways at constant speed. Moreover, an innovative concept for acoustic packages has been defined and applied, achieving a significant improvement in the mid-frequency range and speech intelligibility in the experimental verifications on the road.
