Definitions

  • the present invention relates to a plate-shaped element, in particular for sound absorber systems, and to a sound absorber system.
  • Such plate-shaped elements are known which are continuously perforated.
  • the prior art also includes chipboard with grooves from the visible side or with offset, continuous slots.
  • Longitudinally and transversely grooved panels are also known, the front being longitudinally grooved and the rear of the panel being cross-grooved.
  • There are also plates with a porous material structure. All of these known plate-shaped elements can only be changed within relatively narrow limits in such a way that they are suitable for a broad spectrum of acoustic problems, in particular for sound insulation.
  • the present invention aims to create a plate-shaped element, in particular for soundproofing systems, in which the respective design of the elements can be selected depending on the task and circumstances by changing the relevant parameters.
  • Such a plate-shaped element is characterized by one of the claims.
  • the acoustic element 1 shown in FIGS. 1 to 3 points with its visible side into the room in which the sound source is located.
  • grooves 4 are introduced in the longitudinal direction, which, as shown in FIG. 2, have a rectangular or square cross section with a groove base 5.
  • the back of the plate-shaped acoustic element 1, the so-called absorber side 7, is provided with bores 8, the axes of which in the present case lie in the central planes of the grooves 4 and are perpendicular to the longitudinal axes of the grooves 4.
  • the depth of the grooves 4 is approximately 1/3, as can be seen from FIG. 2 and is indicated there.
  • leading passages 9 are formed, through which the energy to be damped passes from one side of the plate to the other.
  • the absorber side 7 is covered with a stone or glass wool mattress 11, which serves as a destroyer for the energy, in the present case in particular sound energy.
  • FIGS. 4 and 5 Another pattern of the procurement of the passages from the visible side of such an acoustic element, seen from the visible side, is shown in FIGS. 4 and 5 with a differently designed grid of the bores on the absorber side and different distances of the grooves on the visible side. Furthermore, the side areas to the groove bases 5 are connected to one another by rounded end faces 16, which in turn has a specific effect with regard to energy dissipation.
  • the longitudinal grooves on the visible side 2 of the acoustic element have conical groove cross sections 18, while the bores 8 overlap each other in groups such that the passages 9 have corresponding longitudinal dimensions, a further possibility of dealing with this Adapt the problem to be solved by changing the shape and location of the passageways.
  • a side comb 12 on the one long side and a corresponding groove 13 on the other long side are additionally indicated, which allows these elements to be assembled into a more or less large area.
  • Fig. 10 shows the front surface of an element. This is very pleasing because the recessed transverse and longitudinal grooves form 20 and 21 squares. The bottom of the groove can be colored if necessary. It is of course also possible to provide the grooves so that standing or lying rectangles are created. This will depend on the spatial conditions.
  • the absorber percentage can be changed from 0 to 25% of the area percentage.
  • Sound-absorbing elements are installed sandwich-like, with an additional sound-absorbing plate, for example in the form of a chipboard or plasterboard, on the back of the element, i.e. over the absorber mat (stone or glass wool mattress).
  • an additional sound-absorbing plate for example in the form of a chipboard or plasterboard, on the back of the element, i.e. over the absorber mat (stone or glass wool mattress).
  • Such elements can also be used to control the sound energy, i.e. the sound energy, by appropriate choice of material and shape of the recess. find use as so-called sound diffusers.
  • acoustic elements are preferably made from natural wood.
  • the desired sound effect can be optimized accordingly by an optimal choice of solid wood.
  • boards such as plywood, chipboard, MDF and.
  • appropriate carrier plates with cement components for example “Duripanel”, can be used.
  • Acoustic solutions based on biological principles can also be realized through appropriate choice of materials.
  • Such acoustic elements can be of large format, for example with lengths of up to 5 m and widths of 100 to 200 mm and thicknesses of 12 to 20 mm. This information is only for example.
  • the visible side of the elements can with respect to groove depth, groove width, groove spacing, groove inclination and cross-section, and the like.
  • the like variably designed and the surface profiling, e.g. smooth, rounded, concave, convex, etc. and adapted to the requirements at hand.
  • the absorber side or back of the elements can be in terms of hole position, hole depth, e.g. conical holes, hole diameter and hole arrangement as well as hole shape, also meet these requirements.
  • the combination of creasing or profiling on the visible side and perforations in the manner discussed on the rear each result in an optimal characteristic for solving the problem that arises.
  • the surfaces of such elements can be varied as desired, i.e. with natural surfaces, lacquered, stained, glazed, opaque lacquer, painted etc.
