1. A motor vehicle floor covering with a floor covering insulation, comprising a foamed polyurethane foam with visco-elastic properties, wherein the floor covering insulation covers a lower side of the motor vehicle floor covering with the same or different foam compositions in one or more independent or contiguous locally limited regions,
wherein the foamed polyurethane foam of the floor covering insulation has
a modulus of elasticity within a range of from 20 to 250 kN/m2,
a loss factor within a range of from 0.1 to 0.8, and
a density within a range of from 35 to 120 g/l,
wherein the regions of the floor covering insulation have different foamed polyurethane foam compositions with a different compression hardness, and
wherein the foamed polyurethane foam includes EPS, EPP and/or PEPP inlays, wherein a lower surface of the floor covering insulation has adhesive properties and contacts a body when mounted into the motor vehicle.
