Summary:

0The accuracy of nowadays CAE tools for simulation of sound pressure level distributions in the passenger compartment of vehicles is not satisfactory because of the simplify models, especially with regard to the description of common passive acoustical treatments.This report describes the application of the TREASURI method on a complete vehicle, equipped withIn order to validate the method, the simulation results were compared with the measurement results from the corresponding vehicle. The evaluation shows that the TREASURI approach yields considerable improvements in simulation accuracy up to 300 Hz compared to classical approaches [1]. This method now enables reliable predictions of acoustical influence on structural modifications and changes of the sound package
