Definitions

  • Double-skin partition ceilings are generally designed in the form of floating screeds and therefore generally require relatively large construction heights, which are practically hardly feasible, particularly in the renovation of old buildings with mostly predetermined connection heights.

  • Last Distribute 'hands floorboards have much lower surface-related mass than the aforementioned floating screeds. If installed directly on suitable soundproofing layers above the bare ceiling, according to the still prevailing teaching, which can be found, for example, both in the applicable standard ⁇ NORM B 8115 (see Fig. 1), ⁇ NORM B 8115-4, 1992 edition, Table 12 , as well as in the ongoing revision of this standard (proposal ⁇ NORM B 8115-4, version of May 2, 2001, Table 16) is completely identical in terms of content, i.e. dynamic stiffnesses to achieve a correspondingly assessed impact sound reduction s ! full-surface insulation materials of less than or not more than 10 MN / m 3 .
  • German utility model application no. 201 09 885.7 describes an air bubble film made of film webs with barrier materials, which, due to its high punctual resilience and its gas-tightness, can also be used in the construction sector in long-term use.

  • the system consists of one or more layers of deformable material that is designed to absorb vibrations and dissipate them.
  • the mechanical vibrations are reduced within the one or more layers by selecting suitable values for the loss factors. Damping systems of this type are not very suitable due to the different tasks as sound insulation systems for room boundaries in the building sector, since a comparable, completely enveloping inclusion of the sound generator, for example a shoe heel, with damping and insulating layers is not possible.
  • Noise protection systems for room boundary surfaces of the prior art thus have the disadvantage that greater layer thicknesses have to be accepted in order to reduce radiation in the room and a correspondingly assessed impact sound reduction, or only lower impact sound reductions can be achieved.
  • the object of the invention is therefore to create a soundproofing composite system which both reduces the radiation into the room and improves the impact soundproofing, in particular in the case of thin, hard walkings or wall or ceiling coverings.

  • the natural resonance frequency of this spring-mass system is determined not only by the two individual masses, but also by the dynamic stiffness between the load distribution plate and the raw ceiling arranged material determined and should be as low as 85 Hertz if possible according to the prior art. This ensures that as little excitation energy as possible is introduced as a local excitation from walking on the floorboards into the bare ceiling itself via the coupled spring-mass system and is radiated again in (vertically or horizontally) adjacent rooms as airborne sound.
  • the soundproofing system according to the invention is combined with plank floors, these together form a load distribution plate which, in the sense of the desired optimization - and in contrast to more massive floating screeds - represents a "real" pliable shell.
  • this has the effect that the radiation behavior of the floorboards in the space used is not only significantly influenced by the damping of the bending vibrations of the floorboards due to the adjacent damping layer of the soundproofing system, but in particular and very significantly also by the additional damping of the thickness vibrations of the walking surface system via the uniaxial expansion loss factor tan ⁇ c of the footfall sound materials used in the soundproofing system for floorboards being affected.
  • the damping layer made of materials of very high density, for example attached to the underside of the walking surface, possibly glued on, increases the mass per unit area of the thin walking surface - or, in the case of a thin wall covering, its mass - so significantly that it is combined with the suitable dynamic rigidity of the layer of the sound insulation composite system that is effective in terms of impact sound and in combination With massive substructures (also in the wall or ceiling area), the resonance frequency of the overall system is so low that it can also be used in terms of airborne sound or as a sound absorbing plate absorber for room acoustic purposes.

Abstract

La présente invention concerne un système composite d'isolation acoustique pour surfaces de délimitation spatiale. Ce système composite est constitué d'au moins une couche de revêtement (V), d'une couche d'atténuation (D) et d'une couche d'isolation acoustique (S). Selon cette invention, en plus d'améliorer sensiblement le comportement d'émission de la couche de revêtement (V) par rapport à l'émission acoustique dans la pièce, on peut également obtenir une isolation acoustique de qualité en choisissant des combinaisons adéquates du facteur de perte de flexion de la couche d'atténuation, du facteur de perte d'extension monoaxiale et de la rigidité dynamique de la couche d'isolation acoustique (S). De plus, l'ensemble du système peut présenter de faibles épaisseurs de couche, même avec des rigidités dynamiques étonnamment élevées.
