Definitions

  • the invention relates to the field of sound insulation and vibration damping. More precisely, the present invention relates to a floating floor provided with a complex multilayer material making it possible to reduce the noises and vibrations generated by impacts of various loads against the floor, such as for example the floor of a sports hall.
  • the mat does not make it possible to reduce the impacts of large load and of a transient type such as a fall from a heavy object, because a large part of the noise generated by the impact is transmitted directly to the ground located below the carpet, then transmitted to the load-bearing floor generally consisting of concrete slabs.
  • one solution is to place an acoustic insulation underlay between the concrete slabs and the floor.
  • the force of the impact applied to the ground creates a sound transmission path from the ground to the slabs via the underlayer.
