Abstract
A barrier wall (24) separating a passenger compartment from an engine compartment of a motor vehicle has an acoustical barrier assembly (102) mounted thereto. The acoustical barrier assembly (102) includes first and second mat portions (104, 106) juxtaposed to each other in overlapping relationship. Each mat portion (104, 106) is preferably of a molded construction and has sound dampening characteristics. The first and second mat portions (104, 106) each have a terminal edge (130, 122). The terminal edge (130) of the second mat portion is in engagement with one of the surfaces of the first mat portion to thereby acoustically seal the first and second mat portions together. Spacer ribs (124, 132) are integrally with the first and second mat portions (104, 106). Each ribs (124, 132) extends from its corresponding mat portion to the other mat portion. The spacer ribs (124, 132) are preferably adjacent to but spaced from the terminal edges (122, 130) of their respective mat portions to space the mat portions from each other.
