- the disadvantages of the variants a.) - g.) are mainly the high weight and the high cost and the lack of sound absorption. If the variants h.) - m.) Are foamed with foam, the foam forms by the penetration into the fleece (the needle felt or the flocculated nonwoven (HMP process)) or the cut foam a closed layer, whereby the fleece / the cut foam loses much of its porosity. Thus, the acoustic permeability and thus the desired absorption is limited, reduced. Since this closed layer is not concentrated on a thin area and thus no pronounced barrier layer (insulation) is formed, this component does not optimally insulating. Likewise, this results in further acoustic losses, which is the part of the fleece / the cut foam, which is impregnated with foam,
- the nonwovens are usually pressed hard, and a layer is formed in which the foam collapses in the nonwoven (150-800 g / m 2 ). Both significantly worsen the absorption.

- This construction increases the thickness of the absorber in the area with a larger installation space (improvement of the absorption), while in areas with smaller installation space the absorber is more compressed (dual-impedance effect).
- the foam has a constant thickness and / or density, wherein the changes in thickness of the component by space variations in the web 2 done.
- the insulation loss occurring with absorptive insulation with a low weight is optimally compensated or reduced by an optimized thickness adaptation of the absorber by increased absorption.
- this layer 4 preferably has a weight per unit area in the range from 20 to 200 g / m 2 , if appropriate microperforated nonwoven layer 4; 35 to 100 g / m 2 in the case of the microperforated film 4; if it is a microperforated film fleece 4, then this preferably has a basis weight in the range of 65 to 280 g / m 2 .

If the foam layer (3) is a PUR, then this expediently has a density in the range from 20 to 120 g / l, in particular in the range from 45 to 85 g / l. Although higher volume weights bring an increase in the insulation but also an undesirable increase in mass of the material structure according to the invention with it. For too small densities has the

- a demand-oriented absorption distribution is achieved in that the fleece 2 is pressed hard in areas with little space (for foam); and in areas with sufficient space (for foam) is little pressed.
- the foam thickness can be kept significantly more constant over the entire component.
- the fleece 2 is preferably calendered on the foam side, so that there is no collapsing layer between the foam 3 and the fleece 2, which impairs the absorption.
- the foam is coupled fluid-open, so that the absorption capacity of the foam contributes to the total absorption.
- the core of the invention lies in the different degree of compression of the web 2 over the component surface, the relatively constant foam thickness 3, and in the foam side Ankalandrieren of the web, and thus none (a partially very small) formation of an intermediate layer due to foam collapse in the web 2.
