Definitions

  • the invention relates to a sound-absorbing wall with an absorption layer made of sound-absorbing material.
  • Such walls are used in particular to shield residential areas from noise emissions from highways and railways, but of course there are countless other possible uses, especially in the industrial and construction sectors, and in other areas where people are more or more exposed to the disturbance to protect less permanent sources of noise.
  • the absorption layer is therefore preceded by a honeycomb layer, preferably made of corrosion-resistant plastic, possibly also made of aluminum, with directly abutting, continuous openings that are so narrow and long that the honeycomb layer provides adequate protection against birds.
  • a honeycomb layer preferably made of corrosion-resistant plastic, possibly also made of aluminum, with directly abutting, continuous openings that are so narrow and long that the honeycomb layer provides adequate protection against birds.
  • the advantages achieved by the invention lie in addition to the excellent sound absorption capacity and long service life, also in the low weight and the high mechanical stability of the honeycomb layer.
  • the costs are low and aesthetically, a wide range of design options is open due to the arbitrary coloring that the honeycomb layer allows, as well as the possibility of additionally structuring the surface.
  • an 8 cm thick absorption layer 3 is fastened by means of a dowel 2, which consists of a sound-absorbing material of known type, preferably glass wool or rock wool in plate form .
  • the absorption layer 3 is preceded by a honeycomb layer 5 which is approximately 3.3 cm thick and is composed of tubes 6 with a diameter of approximately 5 mm which are laterally bonded to one another and form continuous openings.
  • the wall thickness of the tube 6 is approximately 0.1 mm.
  • a spacer 4 ensures that an air gap remains between the support wall 1 and the absorption layer 3, the thickness of which is approximately 2.5 cm.
  • the tubes 6 have a slope of at least a few percent to the outside, so that rain and splash water run off and the absorption layer 3 remains essentially dry and its function is not impaired.
  • the gradient is not without influence on the absorption properties. With regard to acoustic effects, larger slopes, in particular in the range between 45 and 60%, have proven particularly useful.
  • the tubes 6 are preferably made of a corrosion-resistant plastic, possibly also of metal, are particularly likely Polyetherimides, polycarbonates, ABS or aluminum are suitable. It may be appropriate to apply a protective coating to improve UV resistance.
  • the absorption layer 3 and the honeycomb layer 5 are fixed by a plastic cap 7 which is plugged onto the dowel 2 and anchored to it by means of a catch and can therefore be removed without the dowel having to be removed (for repairs or replacement).
  • the honeycomb layer 5 can be colored as desired, in addition, an additional structuring of its surface z. B. by breaking their function no termination, so that the aesthetic design of the sound absorbing wall opens a wide field of possibilities.
  • the honeycomb layer 5 not only provides reliable protection against attacks by birds on the material of the absorption layer 3, but also, if an air gap is provided between the absorption layer 3 and the support wall 1, the sound absorption compared to an uncovered one Absorption layer over the entire relevant frequency range, but especially in the low frequency range between about 200 Hz and 600 Hz, significantly improved, while known covers clearly deteriorate the relevant properties.
  • FIG 3 shows the sound absorption curves of an uncovered (dashed line) and an absorption layer (solid line) covered according to the invention with a honeycomb layer made of polycarbonates measured in the Kundt tube.
  • Fig. 4 shows the sound absorption curve measured by the reverberation method essentially as above described executed inventive wall.
  • the particularly favorable acoustic properties of the measured wall should be such. T. have also been brought about in that the honeycomb layer 5 has an extremely high proportion of holes of over 92% due to the very small wall thickness of the tubes 6.
  • the material of the honeycomb layer 5 is very light and flexible, which contributes to the very good transmission properties and should lead to the honeycomb layer 5 also making a contribution to sound absorption, especially in the higher frequency range.
  • a further increase in the proportion of holes due to even smaller wall thicknesses of the tubes 6 is desirable and also technically possible with regard to the acoustic properties.
  • the limits in this regard are primarily drawn by the mechanical loads that the honeycomb layer must be able to withstand, depending on the area of application.
