THREE-LAYER ACOUSTIC INSULATOR

摘要

A 3-layer acoustic insulator system includes an acoustic de-coupler layer, a film acoustic barrier layer connected to the de-coupler layer, and a microfiber acoustic absorber layer connected to an opposite side of the barrier film layer as the acoustic de-coupler layer. The acoustic de-coupler layer is positioned in direct contact with a vehicle component and mimics the geometry of the vehicle component. The acoustic absorber layer is positioned on a passenger compartment facing side of the vehicle component.
