Definitions

  • the present invention relates to the use of shredded materials for acoustic damping, in particular for noise barrier walls, where materials are shredded into flakes/fibresand packed into damping elements.
  • a noise barrier forms an obstruction in the landscape, where it causes the sound to follow three possible paths: diffracted over or around the barrier, transmitted through the barrier or reflected by the barrier.
  • a noise barrier would either be an absorptive noise barrier, a reflective noise barrier or a combination hereof.
  • An example of reflective noise barrier is concrete noise barrier walls.
  • the present invention provides a noise barrier, which is a combination of the two types of noise barriers.
  • EP2782731 describes a method for using recycled glass fiber for thermal insulation and sound insulation. A method is described where glass fibers are shredded into recycled granulate and mixed with an adhesive to form a coherent element having a porous self-supporting structure.
  • the disadvantage of this method is that the shredded glass fiber needs to be mixed with a resin, so that it can be formed into an acoustic or thermal insulating coherent element.
  • a resin reduces the porosity of the damping element and thereby the ability to absorb the sound/noise.
  • EP 0762382 A1 and US5484970A both describe a panel for constituting sound insulating wall wherein the sound absorbing members may be bags containing shredded plastic coated with magnetic material such as magnetic tape and magnetic sheet.
  • a method for preparing a noise barrier for acoustic damping is also disclosed.

  • a noise barrier having a front support element, a rear support element and a number of damping elements (bags), where the front support element and the rear support element are arranged at a suitable distance from each other, wherein bags are stacked in the vertical direction between the front support element and rear support element.
  • the bag has a surface wall enabling a mechanical constrainment of the shredded material, wherein the density of the packed shredded material inside the bag is in the range of 200-600 kg/m3.
  • the term "shredded material” or “waste material” covers many different mixtures of materials.
  • the shredded material is a fiber reinforced composite material made of a fiber embedded in or bonded to a polymer matrix material, also referred to as a fiber-reinforced polymer (FRP) or fiber reinforced epoxy (FRE).
  • the fibers are glass or carbon.
  • fibers made of aramid or basalt or fibers like paper or wood or asbestos could also be used.
  • the polymer is usually an epoxy, vinylester, polyurethan (PUR) or polyester thermosetting plastic.
  • shredded or “shredding” should in this context cover any suitable method able to divide the materials into smaller sized pieces or elements, e.g. by cutting, tearing, sawing, grinding and/or milling.
  • waste materials which could be shredded and used, is hawsers used in mooring or towing of ships. Hawsers could be made of polymer materials and/or steel cables are also used for fishing by trawlers.
  • the materials are shredded into flakes/fibres having a length between 1-200 mm, preferably an average length of 5-50 mm. Tests have shown that the shredded materials have good acoustic damping properties.
  • the shredded materials are transformed into a size, where they are easy to handle. This facilitates transporting the shredded material to the place, where it is intended to be used.
  • a shredding mill, flaking mill or portable shredder and/or granulator may be used, which may be transported to the place, whereby the shredding and/or granulation can be carried out at the place of disposal of said material and then transported in shredded and/or granulated form to its place of use or place of further processing.
  • front support element is used to indicate, that the "front” support element is located closest to the noise source, whereas the term “rear” support element indicates that the element is arranged further away from the noise source.

  • the shredded plastic material is packed into each bag.
  • the bag has a surface wall enabling a mechanical constrainment of the shredded material, wherein the density of the packed shredded material is in the range of 200-600 kg/m3. A faster and cheaper manufacturing process is achieved, by the packing of the shredded material in the bag compared to mixing the material with adhesive to form a coherent element.
  • the bag provides a noise damping solution, where the shredded material is constrained inside the bag.
  • the packed shredded material exhibit cavities, channels or interstices, which enable sound waves to enter through them.
  • the use of a porous shredded material inside the bag is favorable in relation to noise damping, as air molecules at the surface of the shredded material and within the pores of the shredded material are forced to vibrate, thereby losing their initial energy. The energy of the air molecules is converted into heat due to thermal and viscous losses.
  • the use of loose fibrous materials densely packed and randomly arranged is advantageous, as sound waves are forced to follow a longer path, whereby energy is lost by the forcing of a directional change of the sound waves.
  • the shredded material contains between 50-90 weight percent of recycled plastic material.
  • the recycled material consist of a combination of recycled plastic material and another recycled material, e.g. hawsers.
  • the bag has a flexible and porous structure enabling ambient air to penetrate into the bag; the bag has a netting structure of a material selected from the group belonging to thermoplastic or thermosetting plastic materials.
  • the bag features a design with a surface wall, which further facilitates mechanical constrainment of the shredded material inside the bag.
  • the fibers of the shredded material would inevitably partially extend out of the bag, whereby the wall structure of the bag would facilitate the shredded material not to be compacted at the end of the bag.
  • the shredded plastic material has a characteristic ability for self-packing, which is advantageous as the shredded material will not subside, when it is stored in the bag.
  • the shredded material has a lot of fiber ends, which would interlock themselves within the netting structure of the bag. The shredded material would therefore be hindered in repositioning inside the bag.
  • the average length of the shredded material is between 1-200 mm, and in another embodiment the average length is between 5-50 mm.
  • a size of the shredded material is achieved, which can be packed into the bag and which according to tests have shown promising acoustic and thermal insulating properties.
  • the bag can be closed off at the ends by the use of different closing means like e.g. a clip (plastic or metal), by folding, by glueing etc.
  • the shredded materials are compressed by a machine suitable for the purpose.
  • the shredded material is hereafter packed into the bag.
  • the machine is able to compress the shredded material to a specified density.
  • the compressed shredded material is guided into the bag.
  • the density of the packed shredded material can be specifically composed for maximizing the absorption and damping of the frequency spectrum.
  • the density of the shredded material is depending upon the frequency spectrum of the sound/noise, as the sound transmission through the noise barrier, and thereby the acoustic energy transmitted through the barrier, is depending upon the barrier material value used, e.g. air tightness, mass, density, surface smoothness, fiber orientation, stiffness, angle of attack of the sound and frequency spectrum of the sound.
  • Each bag is packed with a specific density of the shredded material to optimize the acoustic performance to the specific frequency spectrum of noise to which the noise barrier is exposed.
  • the acoustic performance can be optimized by adjusting the density in the individual bag or by a combination of bags packed with different density of the shredded material.
  • the density of the shredded material inside the bag would be within the range of 200-600 kg/m3.
  • the shredded material can consist of two different densities e.g. ranging 200 kg/m3 to 400 kg/m3 and 450 kg/m3 to 600 kg/m3.
  • the present invention provides a simpler construction of a damping element, where no adhesive bonding material is used. After the shredding and packing of the recycled material, no further manufacturing process in necessary. The shredded material is therefore unlikely to delaminate or disintegrate due to a physical impact as no additional adhesive bonding material is required.
  • the recycled material would not necessary consist of just one type of recycled material.
  • the plastic material could be mixed with a weather-resistant wood.
  • the bag can have different geometrical shapes, e.g. tubular, rectangular or triangular made from UV resistant material.
  • shape of the bag may be slightly modified after filling with shredded material without changing the volume of the bag and hence the density of the filling.
  • the bag may be exposed to sunlight, when it is installed. Therefore, the bag could be made of polymer, which is not sensitive to UV degradation (photo-oxidation).
  • Sensitive polymers include some thermoplastic material like aramids. Through the use of a UV absorber, either added into the material or as a coating, the absorbed UV light, and hereby the polymer degradation, can be limited.
  • the bag is made of an non-elastic woven material or knitted material and said bag is made of a polymer material selected from the group: polyester, polyethylene, polypropylene, nylon etc.
  • Crop cover cloth has a porous structure and it is just one example of a fiber cloth made from polyethylene.
  • An elastic material having a woven structure could also be used; hereby the material would have an incorporated elasticity.
  • the bag is made of a non-elastic material.
  • the bag could also be made of a non-elastic material, which is braided into an open netting structure.
  • a bag with a braided wall structure would contract in the radial direction if the bag is exposed to tension force in the axial direction bag, whereby the contraction would be determining for the density of the shredded materials inside the bag.
  • the material selected for the bag is able to maintain its elasticity during the whole life span, meaning that the elastic creep deformation is neglectable.
  • a method for preparing a noise barrier for acoustic damping which comprises the following steps:
  • the method described in the above can alternatively be used for the manufacture and assembly of noise barrier elements in a production facility prior to installation of the elements in situ.
  • Diffraction is the most important path when a noise barrier is designed, as it defines the sound, which reaches the receiver located on the other side of the noise barrier. Diffraction is the sound, that bends over the top of the noise barrier and into the noise barrier's shadow, and the frequency content of this noise is important as there is a direct relationship between the wave length and the frequency of the sound, where a lower frequency has a longer wave length and a higher frequency has a shorter wave length, and therefore as a result defraction is not uniform over all frequencies.
  • a longer wave length that approaches the noise barrier top easily bends over the top of the noise barrier and down to the receiver, whereas a shorter wave length just slightly reaches over the top of the barrier and does not reach the recipients on the other side.
  • the amount of sound reduction can be referred to as transmission loss, and the transmission loss is influenced by the material used.
  • the sound transmission loss through a noise barrier made of concrete elements is in the range of 20-30 db.
  • the acoustic energy transmitted through the barrier would generally be negligible when it is compared to the diffracted sound over or around the barrier. As a general rule the transmitted sound must be at least 10 db lower than the diffracted sound in order for it to be ignored.
  • the present invention is primarily directed towards noise barriers used for damping highway traffic.
