The growing emphasis on passenger cars, trucks, motorcycles, busses, trains, etc., to be more pleasant and exciting to drive or ride while emitting less noise into the environment makes NVH a key differentiator for vehicle manufacturers. NVH engineering encompasses more than the implementation of a subjective list of features. Social, environmental, legislative and fiscal demands make NVH engineering a focus area for many manufacturers so that in the end, NVH engineers must also converge the following issues in their target setting:

• Dwindling oil resources is driving the development for more efficient powertrain designs

• Growing interest in hybrid vehicles
• Increasing traffic loads are putting high speed trains back on national agendas
• Demands on lower noise in cities put strict requirements on exterior vehicle noise
