Definitions

  • the invention relates to the field of false walls, and in particular that of false ceilings and false walls.
  • the invention relates more particularly to a wall comprising an acoustically absorbent assembly.
  • the assembly is intended in particular, but not exclusively, to be placed inside a room, such as an apartment, a concert hall, etc., in which it is necessary, in addition to hiding unsightly equipment such electric cables, pipes, etc., to control the acoustic behavior.
  • the false walls are produced from frames capable of being fixed to a wall or a ceiling of a room and flexible sheets stretched over these frames.
  • the false walls of the prior art produced with stretched flexible sheets have a major drawback which is to have poor acoustic properties.
  • the stretched sheets indeed reflect the sound waves, thus generating a significant phenomenon of reverberation (or echo) of the sound waves.

  • the constituent material the planar resonator (s) being chosen from a group consisting of a) perforated plastic films
  • the sealing problems are resolved.
  • the presence of the solid fabric influences the overall acoustic performance of the stretched sheet. It has in fact been observed a drop in the absorption coefficient of the stretched sheet, in particular for sound frequencies greater than 300 Hz, to reach unsatisfactory values (less than 0.35).
  • acoustic absorbing assembly intended to constitute, inside an enclosure, at least one wall element, the assembly comprising at least two supports provided with micro-performances and a support not comprising micro-perforation, the support not including micro perforation being placed on the side visible from inside the room.
  • the acoustic assembly described has a satisfactory efficiency, a decrease in the acoustic performance of the assembly is observed for sound frequencies greater than 300 Hz to reach an absorption coefficient below 0.35 for higher frequencies. at 300 Hz.
  • the invention aims to remedy these problems by proposing a sealed assembly and offering satisfactory acoustic properties over a wide range of frequencies, and in particular for frequencies above 300 Hz.

  • the invention provides a wall (1) comprising at least one sound absorbing assembly (10), the sound absorbing assembly (10) being fixed to the wall (1) and consisting of two fabrics (11, 12) parallel to each other and assembled at the periphery on a hooking means, said fabrics (11, 12) respectively defining an internal fabric (12) full said upper fabric and an external fabric (11) said visible lower fabric from said room where the assembly (10) is fixed to the wall, the internal fabric (12) being devoid of perforations, the external fabric (11) is disposed at a distance from the internal fabric (12) of between 30 and 200 millimeters, and characterized in that said external fabric (11) comprises micro-perforations (2) with a density greater than 1000 micro-perforations / m 2 having a diameter less than 0.1 millimeters and arranged to form an acoustic canvas so forming a waterproof sound absorbing assembly (10) he having an absorption coefficient of sound waves greater than or equal to 0.35 for frequencies greater than 300 HZ, and where said
  • external canvas means the canvas visible from the room when the assembly is fixed to a wall or the ceiling, and by "internal canvas", the canvas arranged between the external fabric and the wall or ceiling.
  • Micro-perforations are also understood to mean perforations having a diameter of less than 0.1 millimeter.
  • a canvas devoid of micro-perforations solid canvas
  • a micro-perforated canvas arranged on the visible side of the room, at a determined distance from the non-micro-perforated canvas makes it possible to '' improve the acoustic properties for frequencies above 300 Hz beyond a coefficient of 0.35.
  • the wall (1) comprising at least one sound absorber assembly according to the invention allows as well to achieve watertight walls and having satisfactory acoustic properties in an extended range of frequencies.
  • the wall element may or may not include a frame.
  • the two fabrics will be fixed on a frame intended to be hung on the wall to hide via fixing systems of the hanging type.
  • the two fabrics In the second configuration, the two fabrics will be fixed directly stretched between two walls by means of rails.
  • the internal fabric and the external fabric are arranged at a distance from one another between 30 and 200 millimeters, and preferably of the order of 80 millimeters.
  • the external fabric has a density of micro-perforations greater than 1000 micro-perforations / m2.
  • the external fabric has a uniform distribution of the micro-perforations.
  • the internal fabric is translucent or transparent.
  • At least one of the fabrics is made of polyvinyl chloride.
  • the invention also relates to a wall, of the wall or ceiling type, comprising at least one sound absorbing assembly as described above.
  • the sound absorbing assembly is mounted on the wall of the premises so that the internal fabric is disposed at a distance from the wall greater than the distance separating the internal fabric from the external fabric.
  • the wall includes light means placed between the wall and the internal fabric of the sound absorbing assembly.
  • the internal and external fabrics are translucent. The advantage of such an arrangement is to form a backlit wall offering a satisfactory acoustic behavior, the internal fabric ensuring the diffusion of light while masking the light means due to its translucency, the external fabric ensuring the acoustic behavior. the fact that it has micro-perforations and that it is placed at a determined distance from the internal fabric.
  • the wall constitutes a ceiling
  • the ceiling 1 of a room is described, the ceiling comprising an acoustic absorbing assembly 10 according to the invention.
  • the assembly 10 comprises two stretched fabrics 11, 12, preferably made of polyvinyl chloride (PVC), arranged parallel to each other at a determined distance from one another D1.
  • said fabrics 11, 12 are hermetically assembled at the periphery using a hooking means such as a heddle or a frame (not shown).
  • the fabrics 11, 12 extend parallel to the wall 1 (here the ceiling 1) on which the assembly 10 is fixed.
  • the acoustic assembly 10 is fixed on a support 5 itself fixed to the wall 1.
  • the support 5 and the hooking means are formed in one piece. Provision may however be made for the support 5 to form a separate part from the anchoring means without departing from the scope of the invention.

  • the external fabric 11 (or lower fabric) has micro perforations 2 arranged and distributed on the fabric so as to form a fabric that acoustically absorbs sound.
  • micro-perforations means all perforations having a diameter less than or equal to 0.1 millimeters.
  • the lower fabric has a density of perforations greater than 1000 micro-perforations / m2. It is of course obvious that the invention is not limited to such a density and that the latter can be adjusted according to the acoustic behavior of the desired room.
  • micro-perforations are distributed so uniform on the canvas, this in order to ensure an identical acoustic behavior of the canvas regardless of the location of the sound source in the room.
  • the internal fabric 12 (or upper fabric) is, for its part, a solid fabric, that is to say devoid of any perforation or micro-perforation.
  • the fabric 12 is dustproof.
