Panel Contribution Analysis - An Alternative Window Method

Vehicle interior noise can be regarded as the sum of all panel contributions which enclose the compartment. In order to experimentally investigate the sound contributions of individual panels, the so-called “window method” is often used. Due to some fundamental drawbacks, a new method has been invented which is considered a useful alternative. The theoretical background of the method is covered in this paper, as well as application examples illustrating the performance and advantages of this new technique.
