Definitions

  • the invention relates to a sound absorbing panel according to the preamble of independent claim 1.
  • Sound absorbing perforated panels are well known as wall cladding in the prior art. This works on the principle of the Helmholtz resonators.
  • the sound-absorbing effect of the perforated panels is based on the fact that a significant proportion of the incident sound energy is absorbed, but is no longer reflected.
  • the panels allow the sound to penetrate the interior of the wall through holes, but do not let some of the sound penetrate out.
  • a perforated plate made of a veneered clamping plate is also known.
  • the clamping plate has blind holes with a comparatively large radius, while the veneer has comparatively small holes that guide the impinging sound into the blind holes.
  • the problem with this veneered clamping plate is that it is expensive and complex to manufacture on the one hand and that the holes are easy on the other soiled and can hardly be cleaned. Since this plate is not very flexible, its use is limited accordingly.
  • the invention has for its object to provide a sound absorbing plate of the type mentioned in the preamble of claim 1, which is not only excellent sound absorbing, but also allow numerous variations in the room design.
  • the plate according to the invention also has the Helmholtz effect, but avoids expensive drilling. Measurements in Kundt's tube have an average degree of absorption ⁇ of 0.55. In the range from 500 to 2000 Hz, the degree of absorption rose from 0.6 to 0.9.
  • the plate according to the invention thus has excellent acoustic properties, particularly in the region of the mostly particularly disruptive high frequencies.
  • the millings allow the plate to be shaped and bent without closing the holes. Curved wall surfaces can thus also be clad with shaped or curved panels. The comparatively small holes are hardly visible, which is often desired.
  • the open area is preferably about 2% and the diameter of the holes is, for example, about 1 mm.
  • Such a plate reflects incident light well and is also suitable as a light reflector, for example, over a workplace with noise-generating machines, for example in a computer room.
  • the grooves are funnel-shaped in cross section. This plate is largely self-cleaning. Such grooves are particularly easy to produce if they are V-shaped in cross section.
  • the grooves are V-shaped in the area of the groove base and these grooves have approximately parallel flanks.
  • the distances between the grooves can be chosen to be smaller compared to V-shaped grooves and thus more holes can be created per surface.
  • the plate shown in Fig. 1a is a plywood plate with a thickness of about 7 mm.
  • the plate can also consist of a suitable plastic. Of course, lower or higher strengths are also possible.
  • FIG. 1a in connection with FIGS. 2 and 3, several parallel and straight grooves 3a and 3b are incorporated in surfaces 20a and 20b.
  • the groove depth is approximately 4 mm, so that there are different openings through square openings 5 at the intersections of the grooves.
  • the grooves have parallel flank surfaces 22 and intersecting surfaces 21.
  • the surfaces 21 form the bottom of the groove and intersect approximately at an angle of 90 °.
  • groove 1b shows a further plate 2, in which the grooves 4a and 4b are V-shaped in cross section.
  • the flank surfaces 11 intersect at an angle that is significantly smaller than 90 °.
  • Groove shapes for example, U-shaped grooves in cross section are conceivable.
  • the grooves can also be curved or zigzag-shaped.
  • FIG. 2 shows a plate 2 which is fastened to a ceiling 12, for example as a ceiling covering.
  • the sound impinging on the plate in the direction of arrow 7 enters the grooves 4a through the holes 6.
  • the sound schematically represented here by the lines 8 is absorbed by the material surrounding the grooves 4a.
  • further panels according to the invention or other sound-absorbing panels can be arranged between the panel 2 and the ceiling 12.
  • the plate 1 or 2 is preferably backed with glass wool, rock wool or the like.
  • the sound emerging behind the plate 1 or 2 is scattered by the funnel-shaped grooves and can thus penetrate particularly effectively into the sound-absorbing layer arranged behind the plate.
  • the plate 2 can be partially or completely curved.
  • the plates 1 and 2 according to the invention are very flexible thanks to the intersecting grooves, similar to a plate made of rubber.
  • An essential aspect of the invention is that the inventive Plates 1 and 2 can be of identical design on both sides, which considerably simplifies production and use.
  • the grooves of the front surface can also have a smaller depth than the grooves of the rear surface, or can even be replaced by bores.
