Abstract

The improved comfort of future cars implies a substantial reduction of the noise level in the passenger compartment. A knowledge of the acoustical properties of the air volume limited by the compartment panels is essential in a noise study. The present paper shows how, from a simple mathematical model giving the required properties at low frequencies, it is possible to compute the natural frequencies and modes of the volume (Eigen-values problem) and to find out which panels are responsible for the induced noise in the compartment.
