Abstract
In order to reduce the interior noise level in an automobile, the vibration excitation of the front region of the floor panel is reduced by means of localized gaps between front longitudinal members, on the one hand, and the floor panel, on the other hand, as well as through support of the longitudinal members by a cross member in an approximately middle region of the sill members only, whereas the vibration excitation of the rear region of the floor panel is increased, so that in the head region of the vehicle occupants airborne vibration components are present which in amplitudes as well as phases are suitable to extinguish one another by means of interference.
