Definitions

  • the present invention relates to the provision of acoustic barriers, and in particular to the provision of sound barriers in conjunction with walls, ceilings and the like in buildings.
  • Sound sources in homes and apartments need to be isolated so as not to cause annoyance to people in the house or apartment, or particularly to people in adjacent apartments.
  • Sound striking a solid surface causes the surface to vibrate, just as sounds striking the ear drum cause it to vibrate.
  • Impact noise like footsteps or vibrations from appliances or plumbing can also induce vibrations in a structure.
  • Sound transmission is affected by the ability of surfaces to reflect sound and by the ability ofthe structure to absorb it.
  • Impact noise will be directly transmitted through the structure unless it is dissipated or damped.
  • Airborne noise will be reflected by surfaces but needs to be dissipated by the structure as much as possible, over the range of problem frequencies.
  • Noise management designs need to take a composite system approach by reducing the sound transmission at all possible leakage points.
  • One current method of reducing noise transmission through walls is to provide two wall leaves which are separated by an air gap. That is, two separate but adjacent sets of wall studs and noggings are built, with wall board cladding on the exterior faces of each set. This method has the disadvantages that it is relatively expensive and cannot be retrofitted to abate an existing wall noise without some demolition of existing structures.
  • furring channels are a metal or timber mounting batten which can be used as a simple spacing frame.
  • Furring channels are generally useful where wall board is used as a facing to a main wall of masonry or brick. Furring channel is fixed (usually screwed) to the reverse side of wallboard, cooperating mountings are mounted on the brick or masonry, and the wallboard is installed in place by clipping the furring channel into the mountings. Noise transmission through the assembly can be reduced by using resilient mountings on the masonry or brick.
  • this method of noise reduction has the relative disadvantages that it cannot be retro-fitted where there is an existing noise problem, it is more difficult and expensive to fit, and the resilient mountings must be properly chosen to be sound attenuating at the weight loading which is imposed by the wall board.
  • the present invention accordingly provides an acoustic barrier which includes:
  • a first wall which has a face which is orientated to the exterior ofthe barrier and a face which is orientated to the interior ofthe barrier;
  • a second wall which has a face which is orientated to the exterior of the barrier and a face which is orientated to the interior ofthe barrier; and a layer of flexible material between the interiorly orientated faces ofthe first and second walls.
  • the layer of flexible material is a layer of foam material.
  • the layer of flexible material is adhered to the interiorly orientated faces ofthe first and second walls. It is particularly preferred that the adhesive used for this be a water based contact adhesive, which is catalyst activated.
  • flexible material examples include polyurethane foam, acrylic foam, polyester foam, polyester compressed fibre and natural fibre.
  • the barrier include at least one support pad extending between the first wall and the second wall. It is particularly preferred that each support pad extend from the exterior face ofthe first wall to the interior face of the first wall, through the layer of flexible material and through the interior face ofthe second wall.
  • each support pad be fabricated from a flexible material.
  • Alternative preferred materials for the support pads include polyurethane, polyvinyl chloride, synthetic rubber, natural rubber, polypropylene and silicone.
  • each support pad When the acoustic barrier is to be used for soundproofing walls or ceilings, it is preferred that each support pad have a diameter in the range of 8mm to 20mm. When the acoustic barrier is to be used for soundproofing floors, it is preferred that each support pad have a diameter in the range of 15mm to 40mm.
  • first wall and ofthe second wall include plaster board, particle board, metal, timber and laminated timber.
  • first wall and the second wall are of plaster board
  • first wall and the second wall are of plaster board
  • first wall and the second wall are of plaster board
  • the layer of flexible material have a thickness in the range 5mm to 12mm.
  • Figure 1 is a perspective view of an acoustic barrier according to one embodiment ofthe present invention.
  • Figure 2 is a cross-sectional view on the line 1-1 of Figure 1.
  • Figure 3 is a cross-sectional view of an acoustic barrier according to another embodiment ofthe present invention.
  • An acoustic barrier according to one embodiment of the present invention is indicated generally at 1.
  • the acoustic barrier 1 includes a first wall 6, a second wall 7 and a layer of flexible material 8.
  • the first wall 6 has a face 11 which faces to the exterior ofthe barrier 1 and a face 12 which faces to the interior ofthe barrier 1.
  • the second wall 7 has a face 13 which faces to the exterior of the barrier 1 and a face 14 which faces to the interior ofthe barrier 1.
  • the first and second walls 6 and 7 are separated by a layer of flexible material 8.
  • the layer of flexible material 8 is adhered to the interior face 12 ofthe first wall 6 and to the interior face 14 ofthe second wall 7.
  • First wall 6 and the second wall 7 are also preferably connected by at least one support pad 16.
  • each support pad 16 extends from the exterior face 11 of the first wall 6, through the layer 8 to the interior face 14 ofthe second wall 7.
  • each support pad 16 extends from the exterior face 11 ofthe first wall 6, through the layer 8, through the interior face 14 of the second wall 7 and into the material ofthe second wall 7, but not through the exterior face 13 ofthe second wall 7.
  • the materials ofthe first and second walls 6 and 7 are chosen to be both dense and stiff relative to the material ofthe layer of flexible material 8.
  • Suitable materials for the walls 6 and 7 include plaster board, particle board, metal and timber.
  • Suitable materials for the flexible layer 8 include polyurethane foam, acrylic foam, polyester foam, polyester compressed fibre, fibre-glass batting and natural fibre.
  • Suitable materials for the support pads 16 include polyurethane, polyvinyl chloride, synthetic rubber, natural rubber, polypropylene and silicone.
  • Each ofthe first wall 6 and the second wall 7 according to the present embodiment is a plaster board in the form of a gypsum cement clad on each side with a layer of paper.
  • the first wall 6 is 10mm thick
  • the second wall 7 is 16mm thick.
  • the layer of flexible material 8 according to the present embodiment is a layer of polyurethane foam which is 6mm thick.
  • the support pads 16 according to the present embodiment are of polyurethane and are circular in cross section with a diameter of 15mm. They are placed in staggered rows on 30cm centres, with 15cm spacing between the rows.
  • the support pads 16 according to this embodiment protrude a distance of 7mm into the second wall
  • an acoustic barrier according to this embodiment ofthe invention When used as a wall cladding, it provides an average sound attenuation of between 8dB to 20dB over a frequency range from 125Hz to 4,000Hz.
  • the acoustic barrier 1 is fabricated by providing the second wall 7, and then adhering a layer of flexible material 8 to it. The first wall 6 is then adhered to the flexible material
