Benefits of technology

[0007] According to the present invention, this object is achieved in that the protrusions are arranged with a distribution such that a straight line that is continuous over the surface of the support is not projectable through the interstices. Experiments have indicated that the radial propagation of sound as a result of the impact of, for example, a foot on the covering is substantially reduced, and sound absorption accordingly is considerably improved. Because the sound waves cannot propagate linearly in any direction without encountering protrusions of the sound-absorbing layer, they are intercepted after a short distance, with the consequence that sound absorption is particularly effective. The sound-absorbing device is characterized by ease of manufacture, for example by extrusion of the protrusions.

Problems solved by technology

Production of such a lattice is, however, relatively complicated.
The previously known sound-absorbing devices bring about a sound absorption that is not entirely satisfactory.

Embodiment Construction

)

[0027] The exemplifying embodiment according to FIG. 1 shows a sound-absorbing device 1 that comprises a support film 2 having a sound-absorbing layer 3 applied thereonto. Sound-absorbing layer 3 is constituted by ridges (labeled 4 by way of example) that follow a wave-shaped path, such that ridges 4 proceed substantially parallel to one another. The path of each ridge 4 is respectively symbolized by a line. The spacing of ridges 4 from one another is so close that interstices (labeled 5 by way of example) into which a continuous straight line cannot be projected are formed. In this fashion, the sound waves moving out from a point encounter ridges 4 after only a short distance, i.e. cannot propagate over the entire surface of sound-absorbing device 1, but instead are broken up in each case by the particular shape and arrangement of ridges 4.

[0028]FIG. 2 shows a second sound-absorbing device 6 having a support film 7 and a sound-absorbing layer 8 applied thereonto. The latter is co...

Abstract

A sound-absorbing device for a wall covering, ceiling covering, or floor covering has a support that comprises at least one sound-absorbing layer made of polymer foam. The layer constitutes a plurality of protrusions. The protrusions are arranged with a distribution such that a straight line that is continuous over the surface of the support is not projectable through the interstices.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS AND CLAIM PRIORITY [0001] This application is based upon application number 04 014 185.5, filed Jun. 17, 2004 with the European Patent Office, the disclosure of which is incorporated herein by reference and to which priority is claimed. FIELD OF THE INVENTION [0002] The invention concerns a sound-absorbing device for a wall covering, ceiling covering, or floor covering, having a support that comprises at least one sound-absorbing layer made of polymer foam, which layer constitutes a plurality of protrusions so as to form interstices between the protrusions. The invention further concerns a wall covering or floor covering that is equipped with the aforesaid sound-absorbing device. BACKGROUND OF THE INVENTION [0003] In order to improve sound absorption, in particular footstep sound absorption for floor panels, it is known to equip a panel on the rear side, which is intended for placement onto the floor or wall, with a sound-absorbing device that...
