Definitions

  • the specification of Danish Patent No. 128 947 discloses a sound absorbing ceiling lining consisting of elements of thin perforated sheet material and an absorption material, such as mineral wool batts, disposed in these elements, and an air and particle intercepting foil inserted between the sheet material and the absorption material, said foil being adhered to the sheet material in a cross pattern consisting of two intersecting sets of continuous glue stripes.
  • the foil is preferably a plastic foil having a thickness of about 10v or less, and that it forms a kind of checkered coating on the upper side of the sheet material, the glue stripes dividing the foil into a large number of generally rectangular, possibly square, sections having normally a side length of the order of one or a few centimetres.
  • the stated purpose is to prevent an air flow along the upper side of the sheet material and thereby also to counteract an air circulation through this perforated sheet material, without substantially reducing the sound absorbing effect, especially in the high frequency range, as would be the case when a tight foil were glued flat to the perforated sheet material.
  • the known ceiling lining when applied in practice, has proved not to come up, in all cases, to expectations with regard to the sound absorbing effect.
  • the plastic foil has turned out to have a reducing effect on the sound absorbing capacity of the mineral wool, to such extent, in some cases, that the mineral wool becomes almost ineffective, irrespective of its thickness.
  • this reducing effect varies substantially dependent on the physical characteristics of the plastic foil, especially its composition, its melting point, and its thickness and variations in thickness, and it has been found that these factors can vary in one and the same roll of plastic foil to such an extent as to strongly influence the said reducing effect.
  • the glue stripes constitute a further important factor, as it can be difficult to control their thickness and width with sufficient accuracy, and because they must be expected, by providing a direct contact between the foil and the sheet material, to reduce the effective absorption area proportionally to the area of the glue stripes.
  • the present invention has for its object to provide a sound absorbing structure consisting also of perforated sheet and foil but having a sound absorbing capacity which even under practical conditions can be controlled adequately.
  • the invention relates to a sound absorbing structure consisting, in a conventional manner, of thin, perforated sheet material, such as aluminium sheet, and a foil secured to one side of said sheet, preferably a plastic foil having af thickness of about 10-50p.
  • the structure according to the invention differs from the known designs of same type in that between its securing points, the foil is spaced a distance from the sheet material which is optimum as far as sound absorption is concerned. This can in practice be conveniently achieved by the insertion, between the sheet material and the foil, of a netting which by glueing or welding is attached to the sheet material as well as to the foil and which has a mesh size of the order of 1-5 mm.
  • the sound absorbing effect is due to the fact that the foil is divided into a great number of small areas or small diaphragms, which vibrate or oscillate independently and out of time with the vibrations of the perforated sheet material.
  • a further probable explanation may be that the provision is made between the foil and the sheet material of a layer of air-filled cells to which an access is provided through the perforations of the sheet material. These individual cells have a sound quenching effect.
  • the cavity absorption generally obtained by mineral wool is also obtained by the structure according to the invention, so that additional measures to that effect are reduced to a minimum.
  • the said diaphragms or cells are given a regular shape, for example a quadratic or hexagonal shape, but this is of minor importance, since a gauze-like material, such as glass fiber gauze, has also proved suitable instead of a netting provided with regular meshes.
  • An important advantage of the sound absorbing structure according to the invention is that unintended variations in the applied foil, especially variations in thickness and composition, have practically no importance for the sound absorbing capacity of the finished structure.
  • the desired distance between the sheet material and the foil can also be secured in another way than by sandwiching of netting or the like between the parts in question, as the netting may form part of the foil, or said foil and/or the sheet material may be provided with low ribs or protuberances to secure the required spacing.
  • the structure comprises a rectangular sheet 1 of steel or aluminium which is perforated between the parallel lines 2,2 so that a pair of opposite marginal portions 3,3 are left without perforations.
  • the netting 5 is adhesively attached to both the plastic foil 4 and the metal sheet 1 and forms a layer of air-filled cells therebetween which are closed by the plastic foil or film but communicate with the surrounding air through the perforations of the metal sheet 1.
