Description

The invention relates to an acoustic arrangement for sound absorption according to the preamble of claim 1.

The acoustic arrangement in question is therefore used to improve the acoustics and sound absorption, for example in office, meeting, exhibition or sales rooms.

In modern architecture, the principle of the open floor plan is often used today for the functional spatial organization. In this case, the entire reshaped volume is considered as a contiguous continuum without creating closed subspaces. Rather, individual rooms merge into one another and are separated from each other only by optical elements. The open floor plan should promote communication and the visual connection between employees and / or customers, especially in office, meeting or sales rooms, as well as at trade fairs and museums, and generate synergy effects. Furthermore, an open floor plan also leads to a more generous volume of space and creates a sense of spaciousness. However, such a room design often leads to unpleasant acoustic effects, such as a permanent background noise.

The acoustics of a room depends on the sound propagation and the attenuation of the sound. Sound attenuation is understood to mean above all the obstruction of the sound propagation through sound absorption. The sound absorption causes a conversion of the sound energy into inaudible vibrational energy, so that the reflection of the sound energy is reduced by a surface. In this case, elements having open pores, which have a large inner surface, have proven to be particularly advantageous. If the sound penetrates into the cavities created by the porosity, it is absorbed by these and distributed and thus absorbed.

The from the DE 10 2010 012 202 A1 known acoustics arrangement comprises mobile partition elements which are used simultaneously for sound absorption and the room department. For sound absorption, the partition wall elements on a frame construction with a planking, wherein there is a perforated acoustic panel on the planking. For the department of a whole room often several partitions are releasably connected. The individual partitions run on rails to change the rooms quickly and easily in size.

The disadvantage of this solution is that the position of the mobile partitions is not flexible in space selectable because they are always tied to the given rails. Furthermore, the partition walls create separate rooms, which destroys the open design of a room.

The DE 197 54 107 C1 describes an acoustic arrangement in which a plurality of individual perforated plates or micro-perforated films are arranged at a certain distance behind each other and suspended from a ceiling for sound absorption.

The disadvantage here is that here a large number of elements is needed to ensure the absorption of the sound. This is associated with a high installation cost. Furthermore, the individual elements do not allow a division of a large volume into interlocking spaces.

The invention is based on the problem to design the known Akustikordnung such and further, that the sound can be absorbed in an open space in a simple manner.

The above problem is solved in an acoustic device for sound absorption according to the preamble of claim 1 by the features of the characterizing part of claim 1.

The proposed solution is based first of the consideration that acoustic modules, which in vertical orientation, ie in the direction of gravity, from a holding device, e.g. a ceiling, hanging down, can be used as a room divider, while at the same time ensuring the absorption of sound in a room. This is particularly advantageous in rooms based on the open floor plan principle.

Specifically, it is proposed that one of the first holding device facing away from the narrow side of the first acoustic module and a narrow side of at least one further acoustic module in the assembled state are arranged opposite each other and spaced from each other. Furthermore, it is proposed that the first acoustic module and the respective further acoustic module can be connected to one another via the connections of the opposite narrow sides by means of a fastening device.

Such an acoustic arrangement ensures the spaciousness of the open spaces while positively influencing the room acoustics. Accordingly, the spaces can be made flexible and open, without a permanent and disturbing Noise level arises. Due to the modular design of the acoustic arrangement, it can be adapted to almost any spatial situation.

In the preferred embodiment according to claim 2, at least one further acoustic module is arranged horizontally next to the first acoustic module. In this case, the respective further acoustic module can be fastened via a narrow side to the first holding device by means of a fastening device.

It is conceivable that a plurality of acoustic modules are arranged in a horizontal orientation next to each other in a row hanging. As a result, the size of the arrangement in a simple manner to the customer-specific wishes, the spatial conditions and the acoustic requirements that are placed on the respective Akustikanordnung adapt.

It is preferably according to claim 3 such that at least one further acoustic module vertically adjacent below the respective acoustic module, which hangs horizontally next to or vertically below the first acoustic module, is arranged.

It is conceivable that several acoustic modules are arranged in a vertical orientation in a row with each other hanging. Furthermore, it is possible to combine horizontally adjacent and vertically mutually suspended acoustic modules with each other. The more acoustic modules are combined and interconnected, the better and easier it is to adapt the acoustics of a room and the division of it to the respective use.

It is also conceivable to omit individual centrally located acoustic modules or replace them with non-acoustically effective modules. This loosens up the spatial design so that the pitch and acoustics of a room can be adapted to customer-specific use. A non-acoustically effective module can be, for example, a screen or a picture frame or Plexiglas module.

Basically, according to claim 4, one of the first holding means, e.g. a blanket, opposite second holding means, e.g. a floor, be provided. In this case, the at least two acoustic modules are arranged between the first holding device and the second holding device. In this case, at least one acoustic module, which is different from the first acoustic module, can be fastened via the at least one stationary connection of a narrow side of a second holding device by means of a fastening device.

As a result, the acoustic arrangement can be clamped between the first and the second fastening device. The tension causes the reduction of a back and forth movement of the acoustic arrangement in the case of a wind draft or a bumping of the acoustic modules by passing persons or the like.

To connect the terminals with the fastening device has this according to claim 5, a connecting means. This connecting means connects the terminals positively and / or non-positively with each other.

As a connecting means according to a preferred embodiment according to claim 6, a rigid connecting means or a slippery connecting means is provided. Under a rigid connecting means are understood in particular a rod, a bolt or a sleeve. While a slippery connecting means, in particular a wire rope, a synthetic fiber rope or a natural fiber rope is. Under limber is understood here a form unstable connection.

In order to ensure a simple assembly and to ensure that each acoustic module can be mounted on as many different positions in the acoustic arrangement, it is particularly preferred according to claim 7, when the terminal or the terminals are arranged on each narrow side of a respective acoustic module at the same height ,

Furthermore, it is particularly preferred according to claim 8, when the terminals of opposing narrow sides of adjacent acoustic modules face each other. This supports the modular design of the acoustic arrangement and simplifies assembly.

In the preferred embodiment according to claim 9, the opposite narrow sides of all mutually adjacent acoustic modules extend parallel to each other. Alternatively or additionally, the horizontal and / or vertical spacing of all mutually adjacent acoustic modules is the same.

To positively influence the room acoustics, it is advantageous according to claim 10, if the material layer forming the front side and / or the material layer of the respective acoustic module forming the rear side has in each case a multiplicity of continuous openings. The sound can enter these openings, which affects the reverberation time and the sound is reduced.

Basically, it may also be provided according to claim 11, that the front side, the Rear side and the narrow side or extending along the narrow side frame construction of the acoustic module enclose at least one cavity. In this case, the openings of the material layer forming the front side and / or the openings of the material layer forming the rear side open into the at least one cavity. If the sound enters through the openings in the cavity, so its escape is prevented and thus dampens the sound.

In a preferred embodiment according to claim 12, the at least two acoustic modules in a section parallel to the front and / or back on a same or different geometry. It is preferred if the respective acoustic module in the section parallel to the front and / or back has the geometry of a circle, an ellipse or a polygon, in particular a rectangle.

In this case, the size and geometry of the respective acoustic module and thus the acoustic arrangement can be adapted to the spatial conditions. This allows any combination of sizes and geometries of the acoustic modules, so that a custom design of the acoustic arrangement can also be adapted to the acoustic requirements.

According to the embodiment according to claim 13, it is particularly preferred that the at least two acoustic modules have a length in the length direction and a width in the width direction in a ratio of the length to the width of the respective acoustic module of 2.0 to 2.25 or 1.2 to 1 , 4 or 0.9 to 1.1 or 0.7 to 0.8 or 0.4 to 0.5. This allows a diverse combination of individual acoustic modules of different or the same geometry and dimension.

It is also possible to arrange the respective acoustic modules in the acoustic arrangement rotated by 90 ° about an axis orthogonal to the front side or the rear side, wherein then the ratio of the length to the width of the respective acoustic module can change.

According to the embodiment according to claim 14, it is advantageous if the narrow sides have a depth of 20 to 100 mm, preferably 30 to 80 mm, more preferably 40 to 60 mm, in the depth direction orthogonal to the front side and / or the back.

Furthermore, it is advantageous if the horizontal distance and / or the vertical distance is the same for all mutually adjacent acoustic modules.

The distance between the respective acoustic modules ensures the open spatial design of the desired rooms without having to forego the sound-damping solutions.

In principle, it can be advantageous according to claim 17 if the material layer forming the front side and / or the material layer forming the rear side and / or the material layer forming the narrow side and / or the frame construction of the respective acoustic module consist of a chipboard and / or a fiberboard, in particular a medium density Fiber board (MDF) with soft fiber wool, and / or an OSB board and / or a veneer and / or a laminate, in particular an HPL laminate, is or are.

The medium-density fiberboard has a porous structure and is not too tightly pressed. As a result, a low weight is achieved and additionally improves the acoustic effect. A laminate is understood as meaning a composite material or a laminate which consists of several layers of different material, in particular several layers of paper with hardening synthetic resin. An HPL laminate is a special form of laminate and stands for "high pressure laminates", that is, for a laminate produced by high-pressure compression.

In the preferred embodiment according to claim 18, the front side and / or the rear side of the respective acoustic module has a smooth or structured surface or a pattern. It is particularly advantageous if an orientation of the structure or the pattern of adjacent acoustic modules is different.

By adjusting the surface quality of a particular acoustic module, the acoustics of the room and thus the sound absorption can be further improved and adapted.
