The Role of a Fiber Decoupler on the Acoustical Performance of Automotive Floor Systems 2007-01-2185

The sound absorption coefficient and transmission loss of automotive floor systems with several different fiber decoupler materials are presented. Flooring materials included tufted carpet with and without mass layers and non woven carpet without mass layers. Decouplers included die cut and molded fiber under pads in a range of fiber types and weight. Mass backed floors as well as lightweight dissipative floor systems are compared. The results show a range of performance for sound absorption and transmission loss that allows an NVH engineer to select material combinations to achieve targeted noise reduction in a vehicle.
