Description

The invention relates to an acoustically effective room subsystem and sound insulating properties having frame elements and coupling devices, in particular for the construction of the room subsystem.

Room dividing systems with sound insulating properties are well known in the art and are primarily used to provide partially separated units in larger rooms which also allow some acoustic separation so that neither noise will penetrate to a great extent nor the confined area excessively is burdened by background noise. Also included are tables that can be arranged on a demarcation creating elements and systems.

Such, encompassed by the preamble of the invention device describes the document DE 10 2012 017 901 A1 , It provides a textile acoustic panel in sandwich construction, so with a multi-layered structure, which is provided as a system for attachment to a wall, a ceiling or / and on a table and with the help of feet and suspension devices to a partition or to a room subsystem (see paragraphs 1, 2, 5 and 7). For this purpose, a double-sided panel construction is provided which has an aluminum support frame on which shells for receiving acoustic fleece are provided by means of the force of magnets (paragraphs 1, 3; 3 . 4 . 6 . 9 . 11 . 13a . 13b ). A disadvantage of the proposed solution, however, is the high weight, which is mainly caused by the required shells. Furthermore, a variation of the shape is only possible in size and format (see paragraphs 28, 62, 72, 1a ) possible and provided, which has a restrictive effect on the flexible use. In addition, the acoustic fleece introduced into the shells is itself covered with a flat textile (paragraphs 65, 69). As a result, the mat is not held in the shell or in the panel, it is a separate bracket needed. In addition, a complex connection between the elements and with the set-up or suspension by positive threaded uprights (paragraphs 77 to 81) is provided. This makes it difficult to set up, dismantle and modify the systems.

Other sound-absorbing systems for wall, ceiling or tables are known, for example from the publications DE 20 2010 010 269 U1 . DE 20 2007 002 913 U1 . DE 20 2012 001 857 U1 . EP 0 133 269 A2 or US 4 112 643 A , These systems each require a massive central element that is intended to absorb mid-frequency sound waves, but at the same time is associated with high weight and associated material costs.

Also, for the connection of panel elements to systems various connection or fastening devices have been proposed, for example by the publications WO 1999 058 780 A1 . DE 20 2009 016 304 U1 . DE 20 2006 018 839 U1 . DE 10 2010 034 051 A1 . DE 198 44 028 A1 . DE 198 44 027 A1 . DE 103 26 196 B3 . DE 72 06 572 U or DE 15 34 746 A , However, all connections are made form-fitting with the associated higher effort in all assembly work, quite apart from the cost of the mechanically complicated elements.

A disadvantage of the prior art as a whole, therefore, the expensive and complex structure of the individual panel elements and their high weight. The latter in turn requires very stable, in turn consuming, expensive and heavy fasteners to put the individual elements together to form an overall system and to provide with installation and suspension devices. The dimensions of the elements also allow a flexible structure only limited and prevent forms of the overall system, which differ from the rectangular shape.

Object of the present invention is therefore to provide an acoustically effective room subsystem and sound insulating properties comprising frame members and coupling devices for the construction of the room subsystem, which is at the same time easy, inexpensive and easy to build with effective sound insulation.

The object is achieved by a soundproofing element in panel form, having at least one surface acoustically effective by means of a sound reflector and sound absorber on at least one flat side. If the acoustically effective surface is arranged on a flat side, the soundproofing element can be used as a wall or ceiling element, without being spaced from the respective wall or ceiling. However, a double-sided acoustically effective sound-damping element is considered to be particularly advantageous, which has acoustically effective surfaces on both flat sides. This can then be used to construct partitions, room subsystems and table dividers of various sizes.

In addition, it is also possible to use these sound insulation elements as wall or ceiling elements and to install spaced from the wall or ceiling. The advantage here is that the sound insulation must not be used across the board, because of the interspaces urgent sound from the wall or Ceiling facing flat side of the sound insulation is absorbed.

The parallel to the flat side arranged sound reflector is designed as a one-sided lamination on the side facing away from the outside flat side of the sound absorber. The sound reflector is used to reduce the sound level of the language in the range of low frequencies up to about 800 Hz. Preferably, this is an aluminum foil applied, alternatively another film, for example of another metal or a plastic. The film thickness is preferably between 0.05 and 4.0 mm, more preferably between 0.1 and 1.0 mm. For larger thickness, the film is designed as a plate and this also includes the invention. The particular advantage of such a lamination lies in the fact that the rigidity required for the desired acoustic effects does not originate from the material layer itself, as is the case with the heavy, solid state-of-the-art sound reflectors. Instead, the sound reflector according to the invention obtains its rigidity from the fixed connection with the sound absorber which is used as part of the acoustically effective surface and is preferably designed as a foam plate, ie a sound-absorbing, plate-shaped material, preferably a foam material with special sound-absorbing properties. Instead of the foam, nonwovens of different materials or other sound-absorbing plates, random webs, textile materials or the like can be used.

It is, as described above, particularly advantageous if both flat sides are acoustically effective. For this purpose, a first sound absorber extends over approximately a first half of the cross section of the Schalldämmelements and the sound reflector is arranged approximately centrally in cross section, while extending over a second half of the cross section of the Schalldämmelements a second sound absorber with or without lamination, so that the sound reflector approximately centrally is arranged in the cross section of the Schalldämmelements. The single or double executed sound reflector thus extends approximately centrally in the cross section of the Schalldämmelements. The second, non-laminated sound absorber is also applied to the lamination and also uses this as a sound reflector for the expression of the acoustic properties of the second flat side.

For use, it is provided that the sound absorber is arranged in a frame and covered with a textile covering. The frame allows the handling and arrangement of fasteners. The textile covering protects the sound absorber from damage and dirt. In addition, it enables and supports visual effects, such as coloring or a foam of the sound absorber that appears through the covering, or, in the absence of a sound absorber, a passage of light from the first covering to the second covering. In addition, the clothing contributes to the acoustic effect.

It is particularly preferred if the covering comprises an acoustically effective textile which withstands use loads particularly well. As a result, repeated rebuilds and conversions are possible without contamination or abrasion becoming visible.

Furthermore or alternatively, it is provided in the preferred embodiment that the fabric can be fastened by means of a keder arrangement connected to the fabric in the edge region of a fabric blank. This is achieved in that the piping is countersunk into a groove extending at least partially in the frame, whereby the fabric can be secured securely but easily removable. Thus, it is provided, for example, that the piping consists of a flexible, rubber-like material having an elongated rectangular cross-section and is sewn to the fabric in its edge region. Instead of sewing and gluing, welding or the like are provided. If the piping is now pushed into the groove of the frame, this is a simple, tool-free and easy-to-install fabric available, which also holds the soundproofing safely in the frame.

A further preferred embodiment provides that the material forming the sound absorber has at least one light source. In this connection, a largely translucent fabric is also advantageous. As a result, light effects can be realized that are used as local lighting, for design effects, for signaling or other purposes. For example, it is provided to arrange a row of LEDs in the soundproofing element. Particularly preferred are band-shaped LED, which can be inserted in a slot in the soundproofing element and radiate to achieve different effects either perpendicular to the flat side or in the soundproofing inside. Influence on the effect has also the choice of the covering.

The object of the invention is further achieved by a frame element set for constructing a partition, in which at least a first and a second frame element, each with four different sides, the frame sides, two of which are parallel to each other and at right angles to a first long side arranged narrow sides are provided and wherein the first long side is the same length in both frame members, and wherein the shorter narrow side of the first frame member the same length as the longer narrow side of the second frame member and these narrow sides have half the length of the first long side. By different arrangement of the first and the second frame member to each other, especially when a plurality of first and second frame members is used, a very large number of variants, shapes and patterns can be generated.

Thus, the first and the second frame member can be set with its two equal long narrow sides along or at an angle to each other. The result is a uniformly sloping slope over twice the length of the first long side. If the second long sides are placed against each other so that the narrow sides on both sides of the frame element add up to the same length, a rectangle is also achievable that generates rectangular shapes as in the prior art, but with the possibility of a pattern by different design of the first and of the second frame element. Further diverse possibilities for generating patterns arise in particular if the individual frame elements have different clothing, colors, etc.

In particular, it is also provided to carry out combinations of exclusively first or exclusively second elements and thereby to produce further effects. The purely geometrically determined designs are supplemented by the possibility of producing further effects by means of different textures with different colors or different translucency, which shines through the background.

The preferred embodiment of the invention relates to at least one frame element, which is designed as a sound-absorbing element, as described above. But are also provided frame elements that are used without sound insulation, for example, only with inserted acoustically effective fabric, which is particularly preferably so translucent that light can shine through. This results in further visual effects.

Even without a soundproofing element, it is provided that at least one luminous means, particularly preferably including a largely translucent covering, is arranged in the frame element. In that case, the effects from the translucency for the ambient light are accompanied by the previously described effects which are caused by the means for emitting light or sound used in the soundproofing element.

A further solution of the object of the invention is a coupling device for joining plate-shaped elements at their edges, the frame sides surrounding the plate-shaped element with the same edge width, wherein the coupling frictionally by means of a magnetic force of at least one magnet arranged on at least one edge of the plate-shaped Elements, is provided. The magnet is preferably arranged on an inner side of the plate-shaped element, preferably in its frame, particularly preferably connected thereto, for example by gluing. The magnetic force then acts through the wall of the non-magnetic material of the frame, for example aluminum. The magnet remains invisible and does not affect the visible surface of the relevant side of the plate-shaped element. At least two coupling devices are preferably provided on short frame sides, on longer frame sides.

However, the magnet is particularly preferably placed on the edge on the outside, held for example by a ferromagnetic material, such as steel sheet, attached behind it. The magnet is thereby removable from the plate-shaped element and can be rotated when the polarity is unfavorable, z. B. if on the opposite side also a magnet of the same polarity is used.

Further advantages result when the at least one magnet is inserted in a recess. Then it is positively positioned and can not slip.

In addition, a strong magnet of greater material thickness can be used without it protruding too far beyond the profile of the plate-shaped element.

It has proved to be particularly favorable if magnets are provided on each plate-shaped element. Then a universal assembly of systems of different types is easily possible.

A further preferred solution provides that two magnets are provided on each suitable for coupling edge of a plate-shaped element. Then an arrangement of the coupled plate-shaped elements is secured parallel to each other. Alternatively, mechanical, positive positioning aids could be used. In addition, the magnetic force when using two magnets is twice as large and at the same time distributed over the length of the edge.

Particularly preferred is a solution according to which the coupling between a holding or fastening element and the plate-shaped element is provided. Thereby, the composite system can be placed and fixed at the intended location. For example, this may consist of individual plate-shaped elements assembled system coupled with support feet and placed as a partition, coupled with suspension elements and hung on a ceiling or coupled with a table mount and placed on a table.

A particularly preferred use of the coupling device described above takes place in such a way that a frame element of a frame element set, as described above, is provided as a plate-shaped element.

A further solution of the object of the invention provides a space subsystem comprising at least one frame element set, as also described in detail above, and coupling devices, also as previously illustrated, wherein the frame elements are interconnected by the coupling means. Such a space subsystem has a low weight and is easy to assemble and disassemble. In addition, a wide variety of different combination options is achieved.

For use as attached Raumteilsystem a suspension device is provided for hanging on a ceiling or on a frame. For use as a set-up room subsystem an erector is provided for installation on a floor. It is also envisaged that both possibilities of attachment will also be used at the same time, which may be advantageous, above all, in the case of very high spatial subsystems.

Another possibility for use represents an erector for placement on a table top or a fastening device for attachment to a table top in such a way that a table subsystem is available.

1 shows a schematic sectional view of a Schalldämmelements invention 1 comprising sound absorbers 2 , Sound reflector 3 and covering 4 , The fabric consisting of a textile material 4 contributes to the acoustic effect.

The covering 4 , designed as an acoustically effective textile, is over a flat side 8th the Schalldämmelements 1 curious; excited.

1 shows an embodiment in which only one of the two sound absorbers 2 provided with a lamination and this as a sound reflector 3 is effective. The second sound absorber 2 is directly on the side facing away from the foam flat side of the sound reflector 3 arranged. This is where the sound reflector comes from 3 approximately in the middle of the profile of the Schalldämmelements 1 to the arrangement and is on both sides as a sound reflector 3 effective, namely for sound waves coming from both flat sides 8th on the soundproofing element 1 incident. The second sound absorber 2 therefore does not require its own lamination as a sound reflector 3 , Such an arrangement is very inexpensive, simple and easy. It also takes up little space, since a profile of small width is sufficient to absorb much of the spectrum of frequencies in question.

Furthermore provided is an embodiment in which the two sound absorbers 2 have different strengths. This will be one Layer structure achieved with even lower strength. This is sufficient, for example, in cases in which the main sound load is to be expected from one direction, for example from the middle of the room. Such sound insulation 1 with unbalanced cross-section, for example, in the vicinity of ceilings or walls attachable because of the room from the soundproofing 1 reaching sound waves have a higher intensity than those that are radiated back from the wall or ceiling and the soundproofing element 1 reach only from the back. This back can be in the case with a sound absorber 2 lesser strength.

For reasons of a clearer illustration, spacings are drawn between the sound-absorbing elements with one another and with respect to the covering. In fact, however, all the above elements are directly adjacent to each other.

2 shows a schematic sectional view of a frame profile 11 as a part of the frame elements 15 . 16 , the edge region with preferably completely circumferential grooves 12 is provided. In this case, the outer wall 14 to the outside, while the inner wall 13 to the inner region, which has the sound-absorbing elements, is aligned. The grooves 12 serve the stability of the frame profile 11 but above all, they are suitable, a piping arrangement 9 for fixing the clothing 4 above the sound absorber 2 to absorb, as in the 3 and 4 shown.

The width of the edges 53 of the frame profile 11 is between 1 and 10 cm, preferably between 3 and 6 cm, and is determined mainly by the sound-insulating effect depending on the properties of the Schalldämmelements. Also on the stability of a collection of frame elements 15 . 16 has the width influence, since with narrower frame profiles under load a larger force acts on the connecting coupling elements.

There are different widths of the edges 53 on different frame elements 15 . 16 provided, which can also be combined with each other, so that after assembling a plurality of frame members 15 . 16 to a surface higher or lower areas and corresponding optical effects. On a frame element 15 . 16 is the edge 53 however, the same on every frame page.

3.1 and 3.2 show schematic sectional views of a Schalldämmelements invention 1 and a frame element 15 . 16 including frame profile 11 and covering 4 , In this case, a "disc" is cut out of the sound-absorbing element for clearer representation, so that the back, the frame inside, is not visible. This applies equally to the 4 . 7 and 8th ,

The soundproofing element 1 as shown in 3.1 has a sound-absorbing structure according to the embodiment according to 1.1 with two sound absorbers 2 on, one of which with a sound reflector 3 Is provided. The covering 4 is with a piping to a piping arrangement 9 connected, preferably sewn, alternatively adhesively bonded or welded or joined together in other ways. The piping arrangement 9 gets into the groove 12 pushed in, the dimensions of the fabric 4 are chosen so that they are so tight that they are directly on the sound absorber 2 rest. This preserves the frame element 15 . 16 its outer protective and functional cover.

3.2 shows in terms of the frame profile 11 and the clothing 4 with the piping arrangement 9 a corresponding structure. However, different is the interior of the frame element 15 . 16 because there are no sound absorbers or sound reflectors. Such a frame element 15 . 16 shows a significantly lower sound-absorbing effect, which is caused only by the acoustically effective textile. However, such a frame element 15 . 16 cause special optical effects.

With appropriate choice of clothing 4 In particular, when optical properties such as color and opacity are crucial, a frame element can be used 15 . 16 in the embodiment described above, contribute to the overall impression of a room subsystem. With a translucent fabric 4 For example, daylight can penetrate through or interior lighting devices can have an effect by illuminating the surrounding area or causing visual effects on the room subsystem.

4 shows schematic sectional views of a Schalldämmelements invention 1 including frame profile 11 , Covering 4 and bulbs 21 . 22 . 23 , are caused by the optical effects.

The illustrated, preferably applied installation options of bulbs in the foam need not necessarily on a sound insulation 1 will be realized. The overall presentation is for convenience only, so as not to have to submit a separate drawing for each variant.

For receiving the light sources 21 . 22 . 23 are recesses 24 in the sound absorber 2 contribute. This is particularly easy when using a flexible, thin LED strip 21 . 22 is used. In this case, the sound absorber, which preferably consists of a foam, only slotted and the LED band 21 . 22 be inserted into the slot.

The LED band 21 emits to the outside, so that, depending on the optical properties of the fabric 4 a more or less clear luminous point or a luminous line is created, which can also be used for illumination purposes. In contrast, the LED band 22 designed so that the radiation of the generated light is perpendicular to the tape. Thus, if the tape in the introduced perpendicular to the surface slot in the sound absorber 2 is introduced, the radiation of the light takes place in the foam with the result that there is a diffuse illumination of the foam. The result in turn depends on the properties of the sound absorber 2 , from the light-conducting and light-absorbing properties of the foam used for this purpose.

The third exemplary illuminant is an LED strip 23 proposed, which is formed in a wider recess, formed as a groove, in such a way that a preferably made of metal strip is supported on both sides in the walls of the groove thus created and because of the distance to the sound absorber 2 and the cooling properties of the largely exposed LED strip 23 Even bulbs with higher performance can be used.

In addition to the illumination and design effects already mentioned above, it is also provided, in particular in the case of the last-mentioned variant, to carry out signaling by means of the lighting means, to pass on information or to produce similar communication effects.

5.1 to 5.19 schematically show a selection of arrangements of frame elements 15 . 16 to room subsystems 48 or table subsystems 49 , These and numerous other possibilities of the arrangement are based on the special dimensional ratios of the two basic frame elements 15 . 16 that can be combined with each other as well as with each other. So soft by a compilation of the frame elements 15 . 16 Forms formed not only from the usual rectangular shape, but also allow the design of very different contours. Nevertheless, such a composition is possible, which is able to produce rectangles or only slightly out of the rectangle contours. This makes it very easy to produce a wide variety of combinations and shapes for a wide variety of applications, as well as for specific preferences. By a very simple way, the frame elements 15 . 16 can be separated and put together again, the appropriate spatial subsystem 48 or table subsystem 49 quickly modified and adapted to changing needs or preferences without the need for tools.

Coupling devices allow the flexible composition of the most diverse forms of a room subsystem 48 or table subsystem 49 wherein in one embodiment of the invention frame members are included with different widths of the frame profile, through which in one of frame elements 15 . 16 Compound surface yield higher or lower areas. Accordingly arise in the space subsystem 48 or the table subsystem 49 novel optical effects. The same applies if the compilation of frame elements 15 . 16 to be mounted on a ceiling or a wall.

6 shows a selection of connection possibilities of plate-shaped elements by coupling devices according to the invention 31 . 32 . 33 , So are the frame pages 29 in the present embodiment, the first long side 18 , the second long side and the narrow sides 19 . 20 the frame elements 15 . 16 with coupling devices 31 . 32 . 33 form, equipped herewith. Short frame pages 29 have a coupling device 31 . 32 . 33 , longer frame sides 29 several, preferably two coupling devices 31 . 32 . 33 on.

In addition, setting-up devices, not shown here for installation on the floor or on the table or suspension devices can be attached to the ceiling via the same connection options.

7.1 . 7.2 and 7.3 show schematic sectional views of embodiments of inventive coupling devices 31 . 32 . 33 which provide a very quick and easy way of connecting using magnetic forces.

7.1 shows a soundproofing element 1 with a magnet 35 standing on the inside wall 13 a frame profile 11 attached, preferably glued. Its magnetic force acts through the wall of the frame profile 11 through and is on the outside wall 14 usable, so that a coupling device 31 results. This solution allows a smooth, uninterrupted outer wall 14 in which the coupling device 31 remains invisible.

One limitation, however, is that the polarity of the magnet 35 that is fixed to the inner wall 13 connected, is not changeable. For this reason, it could happen that a second frame element faces with the same polarity and instead of attraction forces, as intended, a repulsion between the magnets 35 he follows.

A remedy for this problem offer the coupling devices described below 32 . 33 at.

7.2 shows a frame element 15 . 16 in which the frame profile 11 however, is broken through, preferably through an opening 36 , Their shape corresponds to that of the magnet 35 , Preferably, it is a round opening 36 , In this the magnet can 35 be used and it is already held by its own magnetic force. This is a ferromagnetic plate 37 , which is thus attractable by magnetic force, provided on the inner wall 13 of the frame profile 11 is appropriate. This coupling device 32 allows the magnet 35 to decrease and, if necessary, to change its polarity, in which he reverses again in the opening 36 is used.

7.3 essentially combines the advantages of the variants of the coupling devices described above 31 and 32 , So is also a ferromagnetic plate 37 on the inner wall 13 of the frame profile 11 provided, while the outer wall 14 unprocessed or, as shown in the embodiment, is provided with a small recess, the exact, positive positioning of the magnet 35 opposite to the externally visible ferromagnetic plate 37 , but above all to the intended location of a cooperating coupling device 31 . 32 . 33 allows.

8.1 and 8.2 shows a selection of possible uses of the coupling devices according to the invention 31 . 32 . 33 and how they cooperate in the field and can be coupled. So is according to 8.1 at a coupling device 31 always a second magnet 35 otherwise it would not attract. As shown, it must then be ensured that always a negative pole and a positive pole come together to form a connection.

In contrast, in the embodiment of a coupling device 32 generally just a magnet 35 required. With correspondingly deep recess 38 this is also the case with a coupling device 33 in the same way the case.

9 shows a table subsystem 49 , attached to a table top with Aufstellinrichtungen 44 . 45 . 46 . 47 , for example, creating jobs using the frame element 15 . 16 can be demarcated against each other and at the same time a sound-insulating effect is caused. As a result, for example, executed by the workplace calls in the area are perceived as less disturbing and the noise level in the room as a whole reduced.

10.1 to 10.4 show Aufstellinrichtungen 44 . 45 . 46 . 47 for a table subsystem 49 that is common to them for connection to a frame element 15 . 16 coupling devices 31 . 32 . 33 with the recess 38 at the Aufstellinrichtungen 44 . 45 . 46 . 47 and on the frame member 15 . 16 for the magnet 35 exhibit. The holder by means of magnetic force allows easy and quick installation of the frame elements 15 . 16 , Furthermore, the Aufstellinrichtungen 44 . 45 . 46 . 47 at least a clamp 50 for connection to the tabletop.

10.1 shows the easy setup 44 by means of a clamp 50 , which may be implemented in the illustrated or a similar manner known in the art, is secured to a table edge.

10.2 shows the erector 45 , in addition to a tilt protection 52 so that the frame element is not subject to the magnet even at higher lateral load 35 solves.

10.3 shows with the erector 45 a variant that allows the frame element 15 . 16 lower it below the level of the table top so that there is no horizontal gap between the table top and the frame element 15 . 16 arises.

10.4 however, shows the Aufstelleinrichtung 47 with which two tabletops can be connected, each by a clamp 50 connected to one of the tabletops. Above the gap between the two tabletops is also with a coupling device with magnets 35 attached, a frame member held by magnetic force.

11 shows a space subsystem with hangers 42 for attaching to a ceiling of a room and setting up facilities 43 for putting up on a floor. Because the room subsystem 48 several rows of frame elements 15 . 16 has over each other, it is not only by means Aufstellinrichtungen 43 placed on the floor, but also has hanging devices 42 on.

The positioning devices 43 are executed in the illustrated embodiment as massive slices, for example, a diameter from 20 cm and a thickness of 3 cm, and by a heavy weight, the space subsystem 48 Stabilize in the state. The connection between the lower frame element 15 . 16 and the Aufstellinrichtungen 43 takes place, as does the connection between the frame element 15 . 16 , by means of coupling devices 31 . 32 . 33 ,

To increase the stability of the room subsystem 48 In itself are in the edge areas, in particular laterally and at the bottom, connecting strips 51 intended. On the narrow sides of the room subsystem 48 are long connection bars 51 provided over the entire height of the room subsystem 48 pass. Alternatively, the use of short connection strips 51 provided that only the junctions of two frame elements 15 . 16 cover and thus avoid unwanted opening of these joints. Also the connection between the connection bars 51 and the frame elements 15 . 16 done by coupling devices 31 . 32 . 33 ,

For better understanding there are connecting strips 51 and erection equipment 43 separately and rotated by 90 ° next to the room subsystem 48 represented by a dotted line.

12.1 and 12.2 show variants on a ceiling of a room suspended partition systems 48 , In this case, the in 12.1 variant illustrated the peculiarity that the frame elements 15 . 16 are not directly connected to each other, but are spaced from each other. The spacing is preferably achieved by providing cable sections with magnets at their ends, in particular magnets 35 as with the coupling devices 31 . 32 . 33 come into use. Other possibilities of spacing are provided, for example on hangers 42 through through holes in the frame elements 15 . 16 passed through and secured therein.

12.2 however, a room subsystem shows 48 similar to how it is in 11 is shown. In contrast, however, that no Aufstellinrichtungen for the ground are provided, but only a suspension 42 ,

In addition to a suspension in the middle of the room to the function as a room subsystem 48 Also, a suspension in the same manner directly on or near a wall has been considered within the scope of the invention. In this case, for example, acoustically adverse effects of smooth walls are reduced or caused decorative effects. Hanging is done in a very simple manner by the corresponding sound insulation elements similar to a picture and can be hung with corresponding known suspension devices.
