Abstract

A noise absorption assembly (20) has a first layer (24) and second layer (26) adhered to the first layer. The first is formed from a polymeric fibrous material that includes mixture of first and second fiber (25, 27) for absorbing the transmission of sound. The second layer (26) is formed form a non-woven polymeric material for providing a barrier to prevent the transmission of sound.
