Definitions
- the invention relates to the field of false-walls, including false ceilings and false walls.
- the invention relates more particularly to an acoustically absorbent assembly for producing false walls.
- 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, besides hiding Unsightly equipment such as electrical cables, pipes, etc., to control the acoustic behavior.
- the false walls are made from frames adapted to be fixed on a wall or a ceiling of a room and flexible sheets stretched on these frames.
- false walls of the prior art made with stretched flexible plies have a major disadvantage that is to present poor acoustic properties.
- Tensed tablecloths reflect the sound waves, thus generating an important phenomenon of reverberation (or echo) of the sound waves.
- EP2472018 also discloses an acoustic absorbent assembly intended to constitute, within an enclosure, at least one wall element, the assembly comprising at least two supports provided with micro-performances and a support not including micro-performance, the support comprising no microperforation being placed on the visible side from inside the room.
- the acoustic assembly described has a satisfactory efficiency, it is observed a decrease in acoustic performance of the assembly for sound frequencies greater than 300 Hz to achieve 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 greater than 300 Hz.
- satisfactory acoustic properties is meant an assembly having a sound wave absorption coefficient greater than or equal to 0.35.
- the invention provides an acoustic absorbent assembly for constituting, within a room, a wall element adapted to being fixed on at least one wall for the production of false walls, comprising two webs parallel to each other and assembled at the periphery on a fastening means, one of the webs being devoid of perforations, said webs respectively defining an inner web and a external fabric when the assembly is fixed on the wall, the acoustic absorbent assembly being characterized in that the outer fabric is disposed at a determined distance from the inner fabric and comprises micro-perforations arranged to form an acoustic fabric.
- outer fabric is understood to mean the fabric visible from the premises when the assembly is attached to a wall or ceiling, and "internal fabric", the fabric arranged between the outer fabric and the wall wall or ceiling.
- Microperforations are also understood to mean perforations having a diameter of less than 5 millimeters. According to a preferred embodiment, the micro-perforations have a diameter of less than 0.1 millimeter.
- the combination of a fabric devoid of micro-perforations (full canvas) and a micro perforated fabric disposed on the visible side of the room, at a determined distance from the non-micro-perforated fabric allows to improve the acoustic properties for frequencies higher than 300 Hz beyond a coefficient of 0.35.
- the acoustic absorbent assembly according to the invention thus makes it possible to produce false and watertight walls having satisfactory acoustic properties in a wider range of frequencies.
- the wall element or not includes a frame.
- the two canvases will be fixed on a frame intended to be hung on the wall to be hidden via suspension type fastening systems.
- the two canvases will be fixed directly stretched between two walls by means of healds.
- the inner fabric and the outer fabric are arranged at a distance from each other of between 30 and 200 millimeters, and preferably of the order of 80 millimeters.
- the outer fabric has a micro-perforation density greater than 1000 micro-perforations / m 2 .
- the outer fabric has a uniform distribution of micro-perforations.
- the inner fabric is translucent or transparent.
- the outer fabric is translucent or transparent.
- At least one of the fabrics is made of polyvinyl chloride.
- the invention also relates to a false wall, false wall type wall or false ceiling, comprising at least one acoustic absorbing assembly as described above.
- the acoustic absorbent assembly is mounted on the wall of the room so the inner fabric is disposed at a distance from the upper wall to the distance between the inner fabric of the outer fabric.
- the false wall comprises light means placed between the wall and the inner web of the acoustic absorbing assembly.
- the inner and outer canvases are translucent. The advantage of such an arrangement is to form a false backlit wall providing satisfactory acoustic behavior, the inner fabric ensuring the diffusion of light while masking the light means because of its translucency, the outer fabric ensuring the behavior acoustic because it has micro-perforations and is placed at a determined distance from the inner web.
- the false wall constitutes a false ceiling
- FIG. 1 shows a schematic partial sectional view of a false ceiling comprising an acoustic absorbent assembly according to the invention
- FIG. 2 represents a graph showing the variation of the sound absorption of the acoustic assembly of FIG. 1 as a function of the sound frequency emitted;
- FIG. 3 shows a partial view of a false ceiling according to an alternative embodiment of the invention.
- the assembly 10 comprises two webs January 1, 12 stretched, preferably polyvinyl chloride (PVC), arranged parallel to each other at a distance from each other determined Dl.
- PVC polyvinyl chloride
- said webs 1 1, 12 are hermetically joined at the periphery with the aid of a fastening means such as a rail or a frame (not shown).
- the webs 1 1, 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 attached to the wall 1.
- the support 5 and the attachment means are formed in one piece. However, it can be expected that the support 5 forms a separate part of the anchoring means without departing from the scope of the invention.
- the upper fabric 12 constitutes a fabric called inner, while the lower canvas 11, visible from the local, constitutes a so-called external web.
- the outer fabric 11 constitutes the fabric arranged on the interior side of the room, while the inner fabric constitutes the fabric disposed between the outer fabric 11 and the wall on which the fabric is fixed. false wall, in this case the ceiling 1.
- the outer fabric 11 (or lower fabric) comprises microperforations 2 arranged and distributed on the fabric so as to form a sound absorbing cloth acoustically.
- micro-perforations are understood to mean any perforations having a diameter less than or equal to 2 millimeters.
- the lower fabric has a perforation density greater than 1000 micro-perforations / m 2 . 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 evenly distributed on the fabric, this to ensure an identical acoustic behavior of the fabric regardless of the location of the source of sound in the room.
- the inner fabric 12 (or upper fabric) is, for its part, a solid web, that is to say devoid of any perforation or micro-perforation.
- the fabric 12 is dustproof.
- micro-perforated web 11 disposed under the non-micro-perforated web 12 makes it possible to preserve satisfactory acoustic properties of the assembly 10, in particular for frequencies of transmitted sounds greater than 300 Hz.
- the graph shown in Figure 3 shows the absorption spectrum of the assembly 10 thus arranged.
- the distance Dl between the two webs 11, 12 is between 30 and 200 millimeters.
- the non-micro-perforated inner fabric 12 is disposed at a distance from the ceiling greater than the distance Dl provided between the micro-perforated fabric and the non-micro-perforated fabric.
- the acoustic assembly is fixed on the wall to "cover” (in this case the ceiling 1). It is of course obvious that it can be provided that the acoustic assembly 10 is fixed on walls adjacent to the wall to be “covered” without departing from the scope of the invention.
- the upper fabric 12 (or inner fabric) is translucent.
- the inner fabric is transparent. The use of this type of fabric, whether translucent or transparent, with or without patterns, makes it possible to advantageously create luminous aesthetic effects, in particular by providing light means in the residual spaces 3, 4 formed respectively between the lower fabric 11 and the upper fabric 12 or between the upper fabric 12 and the ceiling.
- FIG. 3 illustrates the presence of light means 50, 51, 52 in the residual space 4 formed between the upper fabric 12 and the ceiling 1.
- the luminous means 50, 51, 52 are attached to the ceiling 1, away from the ceiling and also on the support 5. It is of course obvious that the invention is not limited to this configuration with regard to the location of the light means and that any other arrangement can to be provided without departing from the scope of the invention.
- the luminous means 51 placed at a distance from the ceiling are represented at the same height with respect to the ceiling 1. It is of course obvious that a positioning of the luminous means can be provided at heights relative to at different ceiling the each other without departing from the scope of the invention.
- the light means 50, 51 are individually fixed on the ceiling 1. It is of course obvious that the means can be fixed to the ceiling via a common base without for all that. depart from the scope of the invention. In order to mask the light means 50, 51, 52, the upper fabric 12 is advantageously translucent.
