    摘要： A device for absorbing and/or damping sound waves has a system for damping and/or silencing sound waves provided with a thin vibratory layer (1) on the side facing the sound waves. In order to improve sound damping and silencing properties, even during a prolonged use with concomitant exposure to strong heat, the thin vibratory layer (1) is made of aluminum or an aluminum alloy and is 0.004 to 0.35 mm thick.

    摘要： A layered absorber for absorbing acoustical sound waves comprising a plurality of layers with at least one layer being spaced apart from another layer by spacers, and at least one layer having a thickness between 0.01 and 5 mm, such spacers being spaced apart from each other between the layers such that gas-filled chambers are formed, wherein the chambers form resonance chambers for acoustic sound waves by tuning the mass-spring pairs of the resonance chambers such that one maximum per mass-spring pair appears in the absorption curve, and wherein a multiple of parallel resonance chambers of a variety of different dimensions of the parallel resonance chambers are formed by varying at least one of the lateral dimensions of the parallel resonance chambers, the densities of the materials of the walls of the parallel resonance chambers, the thicknesses of the walls of the parallel resonance chambers, the rigidity of the materials of the walls of the parallel resonance chambers, the thicknesses of the walls of the parallel resonance chambers and the heights of the parallel resonance chambers in order to reach different sound absorptions in the respective absorption spectra.

    摘要： A panel or housing part of a vehicle is made by heating a semifinished product comprising at least one core layer in the form of a nonwoven fabric made of high melting-point and low melting-point fibers above a melting temperature of the low melting-point fibers and shaping the heated semifinished body under pressure in a mold having a mold gap to produce the panel or housing part. The semifinished product is compacted in the mold in some highly densified regions at the edge of the panel or housing part and/or at a spacing from the edge to produce monolithic regions that are substantially free of gas inclusions such that the material of the semifinished product in these highly densified regions flows along the mold gap, while maintaining in other regions the porosity of the nonwoven fabric of the core layer.

    摘要： A cover part for a vehicle, especially an underbody cover, has a porous core layer and at least one cover layer on each side, wherein the porous core layer is constructed such that it has acoustic transparency or an acoustically absorbent effect. Here, the porous core layer is made either from a thermoplastic matrix with embedded reinforcement fibers, especially glass fibers, whose melting point temperature is higher than the melting point temperature of the plastic matrix, or from a foam, which is either open-cell or closed-cell and perforated. The acoustically absorbent porous core layer is occupied on one or both sides with one or more acoustically transparent or absorbent covering layers.
