Definitions

  • the invention relates to an acoustic panel with slot structure, the sound-absorbing Owns properties.
  • Acoustic panels with parallel grooves are known from DE 34 01 312 A with a designed as a tube plate carrier material, which are performed from the viewing and back or only the visible side with reaching into the continuous tubes slots.
  • plates with grooves running on the visible side and holes machined from the rear side, which meet in the plate are known.
  • the superposition of these grooves and holes results in a special perforation of the plate, which are mainly responsible for the sound-absorbing properties of the acoustic element.
  • the prior art also includes sound-absorbing plates which have parallel grooves on both sides of the plate, which are mutually rotated by 90 degrees from EP 0 388 355 A1 and FR 1,015,972 and meet in the plate due to the chosen groove depth.
  • Acoustic panels with parallel slot structures are also known from DE 198 57 419 A1. These plates have grooves that extend from the visible side and the back into the plate body and meet within the plate structure.
  • the area of the broken slots has proven to be particularly important. In order to meet the requirement of a well-absorbing acoustic panel, therefore, many grooves must be formed with a large area fraction of breakthroughs.
  • acoustic panels with the known slot structures in order to obtain the stability of the plate, it is necessary not to fall below certain material cross sections between the individual apertures, whereby the acoustically usable visible side groove can not be breached over the entire length and therefore the sound absorption capacity of the existing reformrillung can not be fully used.
  • the acoustic panel should be as undisturbed as possible in the drawing of the wood surface. For this it is necessary to keep the surfaces of the visible groove as small as possible.
  • the incorporated grooves should have the clearest possible optical structures and therefore may have hardly any color or structure differences within the grooves.
  • the plates should have as good a sound absorption behavior as possible Frequency range of 250 to 4000 Hz have.
  • the invention is therefore based on the object, a grooved acoustic panel with best sound absorption technology use of the groove cross-sections, the barely light-dark contrasts within the continuous grooves have to construct.
  • FIGS. 1.0 to 3.3 show vertical sections through the acoustic panel and FIGS. 4 to 8 Top views of the acoustic panel.
  • Fig. 1.0 the grooved plate with both sides laterally offset recesses, Fig. 1.1 and 1.2 with one side staggered recesses, Fig. 1.3 with both sides oblique recesses with concave grooving, Fig. 2.0 as 1.3 with convex groove, Fig. 2.1 as 1.2 only with one side oblique edge of the groove and with a rectangular bottom of the groove, Fig. 2.2 with both sides oblique flanks of the grooving and polygonal reason of grooving with outgoing vertical recesses, Fig.
  • the acoustic panel can be due to the special arrangement of the recesses 3,4,12, .13,15,16,17,22,23,24 also incorporated much larger hole cross-sections in the plates and thereby also the absorption behavior can be improved.
  • Fig. 1-3,7 for example, starting from the back of the plate 2 recesses 3,4,12,13,15,16,17,22,23,24 incorporated into the plate elements such that they are the side surface of the break through the visible grooves 5.
  • These cutouts can then each be alternately according to Figure 4 right 3 and left 4 of the visible side grooving 5 are incorporated, which can extend the free cross section of the apertures on the entire length 19 of the visible groove.
  • the panel according to the invention can meet the architects expressed desire for a visually quiet slit with the best acoustic efficiency.
  • Another positive aspect of the acoustic panel according to the invention results from the fact that the incident sound waves at the longitudinal edges 6 broken and passed through the plate 7. At this refraction, the slender disks 8,25,26 of the plates vibrated, resulting in the sound absorption behavior in the frequency range below 1000 Hz clearly to improve. Sound absorption technology are particularly favorable according to FIG. 4 Recesses 9, alternately on both sides, overlapping and laterally the grooving 5 are arranged. Due to this configuration, it is possible to over the entire length of the groove impinging sound through the acoustic panel in the rear-mounted absorber material 10,11 or simply in the Derive substructure, whereby the absorption behavior in the otherwise particularly problematic upper frequency range from 1250 Hz significantly improve leaves.
  • the rear openings 12,13,14,15 obliquely to the plate surface, so that the openings lie laterally behind the preparerillung 5.
  • FIG. 3.0 it is possible to laterally offset the rear openings 16, 17 within the sight groove 3 and to alternately mill 17 from the plate rear side 2.
  • the groove bases 18 are formed obliquely (FIGS. 1.3, 2.0, 3.2).
