摘要

An acoustic insulator assembly for disposition adjacent a rear wall of a vehicle body, between the rear wall and a trim panel includes a substrate formed as a single unit from an acoustic fiber. The substrate includes a first portion, a second portion and a living hinge interconnecting the first portion and the second portion. The second portion is rotated about the living hinge into interlocking engagement with the first portion to define at least one air pocket with at least one baffle. The air pocket and the baffle limiting sound intrusion between a pressure relief valve in the wall of the body and a passenger compartment of the vehicle.
