ABSTRACT:
An arrangement for suppressing droning in vehicle bodies, especially for the rear seats of motor vehicles, which includes a tunnel open in the downward direction for the drive shaft and/or for heating and ventilating lines; a sheet metal closure member thereby covers off the tunnel opening, preferably within the area between the forward seat cross bearer and the rear step in the vehicle floor leading to the rear floor; the closure member is secured at the tunnel edges by way of sound absorbing intermediate layers.
