description A noise absorbing multilayer comprising at least 3 consecutive layers, with a nonwoven carpet facing layer being a first fibrous layer and a back layer being the second fibrous layer and an air flow resistive layer between the first and the second fibrous layer. The air flow resistive layer is a combination of a knit fabric and a thermoplastic resin material whereby the thermoplastic resin material is at least partly penetrated in the knit fabric at least closing part of the pores of the knit fabric.
