Definitions

  • noise barriers In order to remediate this noise pollution, the - Technology - noise barriers erected along rails and streets or else just isolate the windows in question. Such noise barriers help to steer some efficiency, but they do not absorb it or only partially absorb it ... and also disfigure the landscape.
  • rock wool became porous, loose and suitable for the absorption of airborne sound Material examined in the range between 500Hz and 2kHz; so in the frequency range of significant airborne noise emissions from moving railway trains.
  • the study of The density, porosity and layer thickness parameters show that these are used for airborne sound insulation in the railway area can be optimized and that the airborne sound absorption values are comparable to those of snow cover.
  • the method for traffic airborne sound attenuation according to the present invention is used where the noise really bothers, and it works primarily through one Airborne sound absorption directly at, or as close as possible to, the airborne sound sources. Damping through absorption is used alone or with constructions used for noise distraction.
  • the task of noise reduction is solved by the in the characterizing part of the Features mentioned claim 1; preferred designs result from the dependent claims.
  • the airborne sound absorbing material preferably Rock wool
  • the airborne sound absorbing material is adhered to and next to the existing track, whereby, especially with the preferably graveled railway bed, the absorption layer adheres flush to the rails on both sides.
  • the layer is therefore when used in the Rail traffic in direct contact with the airborne sound source, i.e. the rail, as well as between and outside the rail tracks, installed; this causes a big one Damping efficiency.
  • the airborne sound absorption layer is also used to combat road traffic noise installed as close as possible to the airborne sound source to increase efficiency, that is, on the impassable areas: on the median and the verge afterwards on the standing tracks, the guard rails or other boundaries. From there the shift is continued, and if necessary also on an existing one Noise barrier - to improve its effectiveness - pulled up, or else combined with a new, airborne sound-deflecting structure of the "half-pipe" type.
  • the railway and road traffic airborne noise emissions can, so where the noise barriers are already, even without their annoying ones Obstructions can be reduced.
  • Figure 1 shows schematically the arrangement of the airborne sound absorption layer (1) in a single-track train.
  • the airborne sound-absorbing layer is laid flush to the rails (2) and spread over the ballast bed (3), sleepers (4) and the natural ground (5).
  • Figure 2 shows the integration of the airborne sound absorption layer (1) in a motorway with a new or existing noise barrier.
  • the airborne sound absorbing material is pulled up on the noise barrier (6), but also on central (7) and edge strips (8), as well as around any guardrails (9).
  • FIG. 3 schematically shows an airborne sound absorption layer (1) laid using the example of the railway and combined with a “half-pipe airborne sound deflection”.
  • the airborne sound absorption layer is applied to a parabolically curved and firmly anchored structure (10), the shape of which, in accordance with local conditions, is selected for optimal airborne sound deflection.
  • the supporting structure itself consists of appropriately shaped grids with anchored supports and / or correspondingly shaped building ground.
  • the execution of the airborne sound absorption layer from one is particularly advantageous Material that is not only characterized by high absorption, but that at the same time (i) permeable to water and air, (ii) not or only very slowly degradable, (iii) dimensionally stable, (iv) freely formable, (v) non-toxic to humans, animals and Plants, (vi) non-flammable, (vii) color-adaptable, (viii) adhering to the ground and / or anchored to beams and (ix) thus secured against driving and storm winds is.
  • the sum of these properties for example, can be found almost united in the Rock wool specially used for thermal insulation, which is therefore the starting material for the production of airborne sound absorption layers is used. Except for the Rock wool can also do other things - naturally occurring or synthetic Manufactured, organic or mineral - substances for the production of airborne sound absorption layers be used.
  • rock wool - listed here as an example - is produced with the known melting process in a Bessemer pear with subsequent spray process for the extraction of rock wool from the molten rock mass.
  • the necessary dimensional stability of the airborne sound absorption layers is generated by the addition of adhesives and adhesives according to the different Production methods. Likewise, the layers are attached to the grown Floor, on walls, walls, thresholds, crash barriers, supporting structures, etc., the well-known anchoring and adhesive techniques used. Introducing before Location through methods A and B specifically allows for the consideration of local ones Conditions such as signaling systems, visual inspection points, etc.. In the same way also the repair of damaged areas.
  • the thickness and density of the airborne sound absorption layer are the two main ones Parameters for determining the best absorption properties for a given Airborne sound spectrum; the other necessary properties are also optimized.
  • the Airborne sound absorption layer can also be made through two or two cavities be designed in multiple layers. In railway operations, the layer thickness is also affected by the Height of the rail and determined by the rolling stock; outside of this technical You can choose any limits.
