Commercial Vehicle Acoustic Package Optimization

Industry: Automotive

Applications: Optimize Noise and Vibration Procedures

An Asian commercial vehicle OEM approached Sound Answers to receive training in NVH testing methods and SEA modeling strategies to design an optimized acoustic treatment package of a commercial truck. Working in cooperation with a CAE partner Company, Sound Answers developed and implemented a test plan to decompose total noise inside the truck cabin into structure-borne and airborne contributions and developed cost and performance-optimized interior acoustic treatments. An engineer from the vehicle OEM was on-site at Sound Answers and at the CAE partner Company for the duration of the project, to be trained on the NVH and SEA methods used. At the conclusion of the project, NVH results, SEA models and recommendations for acoustic package optimization were delivered to the customer.
