[11] Full Vehicle SEA Model Uses Detailed Sound Package Definition To Predict Driver’s Headspace Acoustic Response

This paper provides an overview of the building and validation process for an airborne SEA model of a typical automotive vehicle using the AutoSEA2® software. The emphasis is placed on identifying the transmission paths as well as sound package characteristics that are most critical to ensure accurate predictions using SEA. It also compares predictions with experimental results of well-controlled load cases. Correlation between predictions and tests is presented and briefly discussed.
