Definitions

  • the invention relates to a broadband sound absorbing Component for walls, floors and ceilings in the generic term of claim 1 genus.
  • the invention is based, sound-absorbing the task To perfect components so that they are easy to manufacture less of maintaining this distance between clad wall or ceiling on the one hand and perforated depend or perforated component and a broadband absorption spectrum Offer.
  • a preferred application of the invention is also that lateral limitation of roadways on which strong Noises occur around the so-called “noise barriers” Sound propagation to areas next to the streets or the like largely to contain.
  • the invention is also applicable to To clad walls, floors and ceilings.
  • Preferred uses are road surfaces, cladding of noise barriers, which when choosing transparent materials such as glass or Plastic, can also be made transparent, Facade components of buildings and cladding Walls, ceilings and / or floors of acoustic measuring rooms, the should remain as sound-free as possible, or from Rooms that are exposed to aggressive media, moisture, Heat or hygienic requirements only with corrosion-free, resistant and easy to clean materials, like stainless steel, aluminum.
  • linings are essentially parallel to the object to be covered, i.e. Floor, ceiling and / or wall of the measuring room.
  • they are also rectangular arrangements of the perforated panels and layers on the clad Structural parts or to the roadway possible.
  • the panels or layers run in a noise barrier essentially vertical, while in the case of cladding by Measurement room walls also an essentially horizontal arrangement the plates or layers can expect good results.
  • Tensioned micro-perforated plastic films are also possible, but also hanging blinds, curtains etc., with which the "acoustics" of a room can be designed variably.
  • the layers or plates can also be used as a carrier for a additional porous and especially made of foamed plastic or serve cover layer formed from nonwoven.
  • the use of a is recommended perforated layer or plate that deforms three-dimensionally is what, in particular, by deep drawing a flat component made of plastic or by injection molding or injection molding in the desired shape can be made.
  • the slot width should be between 0.02 and 0.18 mm amount, while the slot length between 0.02 and 30 mm can be chosen.
  • non-cutting shaping is recommended or discard in particular by stretching to Type of production of expanded metal.
  • the breakthroughs in the form of fine slits and / or holes in the Layer or plate introduced. Thereby or afterwards these stretched and / or three-dimensionally by rolling without cutting deformed. In many cases it is also advisable to use the openings partially press again when rolling to make the small ones Observe miniature dimensions.
  • the plate 1 is provided with an abundance of slot-like openings 2, which have a slot length 1 of 1.6 mm in particular and a width b (at the widest point) of 0.09 to 0.1 mm.
  • Figure 2 shows another embodiment of the invention, the more the expanded metals previously used for other purposes corresponds.
  • the plate 1 with a layer thickness L of 0.5 mm first slit open with a knife bar and stretched so that the narrow slots are about spread diamond-shaped openings 2, simultaneously a chipless rejection of the originally flat surface of the Plate 1 is done.
  • the slot width b is in the finished Component according to Figure 2 about 0.1 mm with a web width c of about 0.03 mm. The representation is not to scale.
  • the number of slots is 1000 / m over the length of the component and the number of slots 400 / m across the width or height of the installation part, i.e. parallel for the longitudinal extent LE of the slot-shaped openings 2.
  • the plate 1 made of polypropylene has a hole 2 with a substantially circular cross section at a certain point.
  • the hole 2 has a diameter D of, for example, 0.5 mm.
  • the acoustic waves W A impinging on the perforated plate 1 are largely reflected as reflection waves W R on the surface of the perforated plate 1, while another portion, namely the waves W D passing through, penetrates into the hole 2 and has physical effects in the gas volume located there initiated, which lead to a much larger absorption of the total incident waves than this corresponds to the hole area ratio LV.
  • the component with other layers is one multilayer absorber element connected. You can several individual layers 1 by choosing the right one Perforation again compared to a single layer lead to a significant increase in broadband. Especially in low frequency range this allows absorption continue to improve. Spacers 11 hold the individual layers 1 forming air layers or gaps 12 in Distance from each other.
  • Figure 6 is the attachment of one of four individual layers existing multilayer absorber element in front of a wall 10 shown schematically in cross section. Here too are spacers 11 used.
  • FIG. 7 there is a corresponding multilayer absorber attached to both sides of a noise barrier 10.
  • the Spacers can also be called “cassettes”, i.e. on four sides delimited by walls and on the two end faces open box-like structures.
  • FIG 8 are in front of the wall 10 and at right angles this the individual plates 1 immediately after this at a distance from each other and at right angles to Wall 10 arranged.
  • the component arrangement can be in the manner of a "Shelving system” but also in the manner of a “honeycomb system” in particular rectangular honeycomb structure.
  • the elevation is one of the walls 10 bounded Measuring room shown.
  • the walls 10 are inside with a multilayer structure of flat component plates according to the invention 1 shown, which are separated from one another by spacers are.
  • Figure 10 is a floor or road surface in cross section shown, which in turn consists of several layers 1 of the invention Perforation is built up at a distance from each other are arranged one above the other and especially different Have perforations.
