Abstract
The investigation of the static behaviour of structures, especially car bodies, by analytical methods is a very important and widely used tool in the automotive industry. It is much more difficult to predict noise phenomena. The key point is that many physical quantities determine the sound in the car (1)*. The relevant physical effects must be identified in order to get a reliable mathematical model. The paper describes how this can be done by a combination of experimental and analytical works. The frequency range of interest is up to 200 Hz
