Definitions

  • the invention relates to an acoustic absorber according to the preamble of claim 1 and to a use of such an acoustic absorber according to claim 13.
  • Acoustic absorbers for absorbing sound waves or for the acoustic design of spaces formed in the form of an apertured plate are known in the art.
  • the DE 43 32 856 A1 a perforated, coated with a porous paint layer metal plate as a sound absorber.
  • the problem underlying the invention is to enable as simple as possible and yet as efficient as possible sound absorption.
  • the coating takes place in particular on a "visible side" of the carrier, i. one side of the support which is visible after assembly of the absorber, e.g. facing away from a mounting point (such as a wall).
  • a visible side of the absorber is also the side that is to be turned to a sound source.
  • the coating is provided on several sides, in particular on mutually applied sides of the carrier.
  • Sound waves impinging on the absorber partially enter the recesses of the carrier, dissipating sound energy and correspondingly attenuating the sound waves.
  • the paint coating By covering the openings with the paint coating this effect is enhanced.
  • the lacquer coating above the recesses in each case has at least one opening which causes a constriction of the recess and thus an increased (friction-induced) dissipation of the sound energy.
  • the variant of the invention according to which the sections of the coating covering the recesses are made impermeable to air, can be used in particular if the surface-related mass of the coating is small.
  • the air-impermeable design of the coating segments has the particular advantage that a substantially homogeneous, planar surface is obtained, which is e.g. can be easily cleaned.
  • the segments can each be formed at least substantially closed. This means, in particular, that the segments (or, for example, also the entire coating) do not have an open-pore lacquer material.
  • the recesses run slit-like, ie they have a longitudinal extent which is greater (for example, three times larger) than their width.
  • the openings in the lacquer layer are each approximately in the form of a gap running transversely to the slots, wherein the gaps each have, for example, a width of 0.1-0.2 mm.
  • the lacquer layer is produced (for example in the form of a powder coating or dip coating)
  • the lacquer is drawn somewhat into the recesses due to capillary forces and thereby tears transversely to the recesses, as a result of which the segments of the lacquer coating covering the recesses separate from each other.
  • the paint coating closure elements are introduced into the recesses, which serve to stabilize the paint coating in the region of the recesses.
  • the closure elements can remain in the recesses after removal of the lacquer coating or can also be removed.
  • the recesses in the cross section are at least approximately circular, i. as holes.
  • the recesses go in particular through the entire carrier.
  • the recesses are arranged in a regular pattern and / or e.g. for displaying an image information, in particular for the pictorial representation of an object serve.
  • the recesses (in particular in the manner of a perforation) are arranged along a plurality of lines (contour lines) which represent the contours of an object.
  • the recesses do not have to have the same shape, size and / or geometry.
  • the distances between adjacent recesses vary.
  • several (for example different) lacquer coatings are arranged one above the other, wherein each of the lacquer layers has recesses.
  • the recesses of the different lacquer layers are in particular arranged so that they at least partially overlap each other.
  • the carrier may be at least substantially planar.
  • the invention is of course not limited to a particular nature of the carrier. It is conceivable, e.g. Also, that the carrier is formed at least partially curved, folded or stepped.
  • the basic shape of the carrier (in plan view) also need not be rectangular. Rather, in principle, any basic shapes come into question (for example, round or jagged).
  • the carrier is, for example, a metal or plastic plate.
  • the invention also relates to the use of an acoustic absorber designed as described above as a surface cladding element, as a ceiling or wall element or as part of a furnishing object.
  • the invention relates to a piece of furniture with an acoustic absorber designed as described above.
  • the furniture is, for example, a shelf (such as a sales or presentation shelf).
  • a shelf such as a sales or presentation shelf.
  • floors of the shelf and / or at least one rear wall element are each formed by an acoustic absorber according to the invention. It is also possible that all floors and the rear wall are each formed by an absorber according to the invention.
  • Fig. 9 and 10 acoustic absorber according to further embodiments of the invention.
  • FIG. 1 shows a plan view of a visible surface 21 of a support 2 of an acoustic absorber according to the invention 1.
  • the carrier 2 has a plurality of recesses in the form of slots 22, which cause an increased energy dissipation of sound waves acting on the absorber 1.
  • the visible surface 21 of the carrier 2 is provided with a lacquer coating 3, which covers at least some of the slots 22 with portions 31.
  • the portions 31 of the lacquer coating 3 are somewhat drawn into the respective slot 22 due to the action of capillary forces.
  • the sections 31 each have a plurality of segments 311, which transverse to the longitudinal propagation of the slots 22 extending openings in the form of columns 312 are separated from each other.
  • the gaps 312 reduce the slits 22 in their upper area, thereby increasing the dissipation of sound wave energy.
  • the gaps 312 occur, in particular, during the production of the lacquer layer 3, the number of gaps depending on the width of the slots 22 and / or the nature of the edges of the slots.
  • column 312 is as in Fig. 1 shown not necessarily have to have a constant width. In the present case, the gaps 312 each widen outwardly from their center (in the middle of the slots 22) (toward side walls of the slots 22).
  • recesses instead of the slots 22 (at least instead of some of the slots 22), recesses of a different geometry, e.g. circular bores or star-shaped openings, can be used.
  • the recesses in particular the slots 22
  • the recesses can be generated in basically any manner, e.g. cut, split, stamped, sintered or etched.
  • the carrier 2 is in particular a material plate (for example a metal plate).
  • the carrier it is also conceivable for the carrier to be a foil, rod arrangements or wires with joints (as recesses), fibers, threads with joints or fabric, nonwovens, knitted fabrics, knitwear, in which the joint distances (ie the distances of the fiber or threads) be chosen so that they can be bridged by the paint coating 3 (prepared by any coating method).
  • Fig. 2 shows the absorber 1 of Fig. 1 in cross section.
  • the lacquer coating 3 as mentioned, in each case something is drawn into the slots 22 and correspondingly in the region of the slots 22 has indentations.
  • the coating 3 runs flat, as in the alternative cross-section of Fig. 3 shown.
  • coating 3 of Fig. 3 For example, it is a coating that closes the slots 22 at least approximately airtight.
  • the Fig. 4 shows a further embodiment of the absorber according to the invention 1.
  • the carrier 2 of the acoustic absorber 1 then has a plurality of layers 2a - 2c on.
  • the layers 2a-2c each have recesses 22a-22c, which are partially aligned with one another and thus form the (sound-damping) recesses of the carrier 2.
  • the visible side of the carrier 2 is provided with a lacquer coating as above with respect to the other exemplary embodiments (or has a foamed or impermeable lacquer layer in the region of the cutouts 22a-22c).
  • the recesses 22a-22c can in principle be configured and arranged as desired. Another possible configuration shows Fig. 5 ,
  • Fig. 6 shows an absorber 1 according to the invention with an irregular arrangement of (rectangular) recesses 22.
  • the recesses 22 are arranged in particular with regard to an optimized sound absorption.
  • Fig. 7 a further possibility of the arrangement of the recesses in the carrier 2 is shown. Thereafter, the recesses are in the form of a variety of (in Fig. 7 unresolved) bores 22 (small diameter perforations) are arranged along several lines 220.
