VA ONE - SEA for Automotive Applications

Learn how to build a SEA model of a car and perform sound pack analysis.
NVH Engineers, Acoustic Test Engineers, etc.

Basic knowledge of acoustic, NVH, and of CAE software.


This course focuses on an introduction to VA One SEA for automotive applications. The trainee will learn how to build a SEA model of a vehicle from a FE Model to be able to perform sound pack analysis and interior noise performance assessment.
