Transmission Loss of Vehicle Components Using Virtual SEA: Validation and Modeling Challenges

<div class="section abstract"><div class="htmlview paragraph">In the automotive industry, controlling noise transmission through vehicle components is essential for passenger comfort and regulatory compliance. Traditionally, Transmission Loss (TL) is estimated using simplified CAD-based metrics, which lack accuracy at high frequencies and for complex assemblies. Modeling complex vehicle components introduces challenges, such as representing fluid-structure and trim interactions, with
