Definitions

  • the invention relates to a tile for flooring or wall acoustic enhancement properties.
  • Tile means a ceramic-based tile such as earthenware, terra-cotta, sandstone, a glass tile, a marble tile, a reconstituted stone slab, or a slab made of composite material rigid that is such that one can walk on the slab when it is a floor covering.
  • the invention also relates to the coating obtained by the combination of several tiles with acoustic enhancement properties.
  • the main difference is improvement by acoustic insulation and improvement by acoustic correction.
  • Sound insulation reduces noise transmission from room to room, floor, ceiling or sidewalls. Sound insulation reduces mechanical noise, such as impact or impact noise, as well as airborne noise such as speakers or HiFi equipment:
  • Acoustic correction reduces the noise in the room where the sound source is located. Acoustic correction is for mechanical noise and airborne noise. In the case of mechanical noise on a floor, it is called acoustic noise correction when walking.
  • the floors are provided with acoustic underlayments on which the tiling type flooring is laid.
  • acoustic underlayments on which the tiling type flooring is laid.

  • the patent application FR 2,361,515 proposes to stick polystyrene plates on the ground then to pour a mortar screed made of a mixture of cement, sand and rubber. Once the screed dries, we stick on the tiles.
  • the patent EP 0 413 626 B1 discloses a soundproofing slab with a hard surface facing the coating to be laid such as tiling, and support elastic reaction opposite. It comprises a dense and flexible sheet of supercharged fibers with a density of between 60 and 200 kg / m 3 which constitutes the elastic reaction medium, and a layer of bitumen reinforced by two thin layers of glass fibers anchored respectively in each of the faces of the bitumen layer to constitute the rigid face of the slab, the rigid layer having a thickness of about 5 to 6 mm with a basis weight of about 10 kg / m 2 .
  • the document FR 2,693,221 proposes an isolation solution in the form of rolls.
  • This underlayer has a main layer which is disposed on the side of the coating and a secondary layer which is arranged on the opposite side, ground side.
  • the secondary layer is a material which is for example based on a polyvinyl chloride (PVC), polyurethane rubber (PUR), polyethylene (PE), butadiene-styrene rubber (SBR) polymer, and has a thickness between 0.1 mm and 5 mm, with a density not exceeding 800 kg / m 3 .

  • Its constituent material is for example a synthetic polymer such as polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), or a bitumen, but can also be made from original materials natural fibers such as wood fibers.
  • This layer is relatively hard on the surface but remains flexible enough to be rolled so that the underlayer can be in the form of rolls.

It will be noted that the measurements of the Young's modulus and the loss factor are carried out in a known manner using a viscoanalyzer.
  • the inventors have demonstrated that it was necessary for the layer of damping material to be sandwiched between the two rigid elements that are the tile and the support of the floor or wall type to achieve all its damping function by its work. in shear. This characteristic results in the impedance break (pronounced discontinuity of the stiffness of materials) which must exist between the tile and the damping material as well as between the damping material and the support. The shearing work of the damping layer then makes it possible to dissipate the energy.
