NVH Highlights and (Pot)Holes 1972-2001 2003-01-1517

The NVH performance of motor vehicles has been improved dramatically during the 1972-2001 period. The paper identifies the main advances made, i.e. the development highlights and indicates a number of points where a lot of work still needs to be done (Holes or with and automotive flavor “Potholes”).
The paper is structured as indicated below.
