Abstract: A sound damping system for a swinging tail gate of a dump truck is described. The system comprises a two-part seal formed by a compressible sound damping material and a rigid compressing projection. One part of the two-part seal is secured along opposed vertical edges of opposed side walls of an open-top-end box of the truck. The other part is secured on opposed sides of an inner wall of the tail gate and aligned for facial contact with the first part. The tail gate is hingedly secured at a top end thereof to the opposed side walls of the box. The sound damping system also provides a more efficient sealing system between the gate when in a closed position with the box of the truck.
