Definitions

  • 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 acoustics and sound absorption, for example in office, meeting, exhibition or sales rooms.
  • an open floor plan In modern architecture, the principle of an open floor plan is often used for functional room structuring.
  • the entire volume that has been converted is viewed as a coherent continuum without creating closed subspaces. Instead, individual rooms merge into one another and are only separated from one another by optical elements.
  • the open floor plan is intended to promote communication and the visual relationship between employees and / or customers and generate synergy effects, especially in office, meeting or sales rooms, as well as at trade fairs and museums.
  • an open floor plan also leads to a more spacious room and gives a feeling of spaciousness.
  • such a room design often leads to unpleasant acoustic effects, for example to a permanent background noise.
  • the acoustics of a room depend on the sound propagation and the attenuation of the sound.
  • Sound damping is understood here to mean, above all, the impediment to sound propagation through sound absorption. Sound absorption converts the sound energy into inaudible vibration energy so that the reflection of the sound energy from a surface is reduced. Elements with open pores that have a large inner surface have been found to be particularly advantageous. If the sound penetrates into the cavities created by the porosity, it is absorbed and distributed by them and thus absorbed.
  • the one from the DE 10 2010 012 202 A1 Known acoustic arrangement comprises mobile partition elements which are used simultaneously for sound absorption and for room division.
  • the partition elements For sound absorption, the partition elements have a frame construction with planking, whereby there is a perforated acoustic panel on the planking.
  • To partition an entire room several partitions are often detachably connected. The individual partitions run on rails so that the size of the rooms can be changed quickly and easily.
  • the DE 197 54 107 C1 describes an acoustic arrangement in which, for sound absorption, a large number of individual perforated plates or microperforated foils are arranged one behind the other at a certain distance and suspended from a ceiling.
  • the disadvantage here is that a large number of elements are required to ensure the absorption of the sound. This is associated with a high installation effort. Furthermore, the individual elements do not allow a large volume to be divided into interlocking rooms.
  • the invention is based on the problem of designing and developing the known acoustic arrangement in such a way that the sound in an open space can be absorbed in a simple manner.
  • the proposed solution is initially based on the consideration that acoustic modules which hang in a vertical orientation, i.e. in the direction of gravity, from a holding device, for example a ceiling, can be used as room dividers while at the same time ensuring the absorption of the sound in a room. This is particularly advantageous in rooms that are based on the principle of an open floor plan.
  • a narrow side of the first acoustic module facing away from the first holding device and a narrow side of at least one further acoustic module be arranged opposite and spaced apart from one another in the assembled state. 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 rooms can be designed flexibly and openly without creating a permanent and annoying noise level. Due to the modular structure of the acoustic arrangement, it can be adapted to almost any spatial situation.
  • At least one further acoustic module is arranged horizontally adjacent to the first acoustic module.
  • the respective further acoustic module can be fastened via a narrow side to the first holding device by means of a fastening device.
  • a number of acoustic modules are arranged in a row in a horizontal orientation hanging in a row.
  • the size of the arrangement can be adapted in a simple manner to the customer-specific wishes, the spatial conditions and the acoustic requirements that are placed on the respective acoustic arrangement.
  • At least one further acoustic module is arranged vertically adjacent to the respective acoustic module, which hangs horizontally next to or vertically below the first acoustic module.
  • a plurality of acoustic modules are arranged in a row in a row, hanging from one another. It is also possible to combine acoustic modules that are horizontally next to each other and vertically one below the other. The more acoustic modules combined and connected with each other, the better and easier it is to adapt the acoustics of a room and the division of it to the respective use.
  • a non-acoustically active module can be, for example, a screen or a picture frame or plexiglass module.
  • one of the first holding devices e.g. a blanket, opposite second holding device, e.g. a floor
  • the at least two acoustic modules are arranged between the first holding device and the second holding device.
  • at least one acoustic module which is different from the first acoustic module, can be fastened by means of a fastening device via the at least one fixed connection of a narrow side of a second holding device.
  • the bracing reduces the back and forth movement of the acoustic arrangement in the event of a breeze or the acoustic modules being knocked by people or the like.
  • this connecting means connects the connections to one another in a form-fitting and / or non-positive manner.
  • a rigid connecting means or a flexible connecting means is provided as the connecting means.
  • a rigid connecting means means in particular a rod, a bolt or a sleeve.
  • a flexible connection means in particular a wire rope, a synthetic fiber rope or a natural fiber rope. Bend-limp is understood here to mean a dimensionally unstable connection.
  • connection or the connections on each narrow side of a respective acoustic module are arranged at the same height .
  • connections of opposite narrow sides of adjacent acoustic modules are opposite one another. This supports the modular design of the acoustic arrangement and simplifies assembly.
  • the mutually opposite narrow sides of all acoustic modules adjacent to one another run parallel to one another.
  • the horizontal and / or the vertical distance of all adjacent acoustic modules is the same.
  • the material layer forming the front side and / or the material layer forming the rear side of the respective acoustic module in each case has a multiplicity of through openings. The sound can enter these openings, which affects the reverberation time and reduces the sound.
  • the front, the back and the narrow side or a frame construction of the acoustic module running along the narrow side enclose at least one cavity.
  • the openings of the material layer forming the front and / or the openings of the material layer forming the rear open into the at least one cavity. If the sound enters the cavity through the openings, it is prevented from escaping and the sound is thus damped.
  • the at least two acoustic modules have a cut parallel to the front and / or back have the 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.
  • 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 customer-specific design of the acoustic arrangement can also be adapted to the acoustic requirements.
  • 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 enables a diverse combination of individual acoustic modules with different or the same geometry and dimensions.
  • the narrow sides have a depth of 20 to 100 mm, preferably 30 to 80 mm, further preferably 40 to 60 mm, in the depth direction orthogonal to the front and / or to the rear.
  • the material layer forming the front side and / or the material layer forming the rear side each have a depth of 2 to 15 mm, preferably 3 to 10 mm, further preferably 4 to 6 mm, in the depth direction.
  • the distance between the opposite narrow sides of the respective acoustic modules is preferably Claim 16, 50 to 200 mm, preferably 70 to 150 mm, more preferably 90 to 120 mm. It is furthermore advantageous if the horizontal distance and / or the vertical distance is the same for all adjacent acoustic modules.
  • the distance between the respective acoustic modules ensures the open spatial design of the desired rooms without having to do without the sound-absorbing solutions.
  • MDF medium density Fiberboard
  • 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 is a particle board and / or a fiberboard, in particular a medium density fiberboard (MDF ) with soft fiber wool, and / or an OSB board and / or a veneer and / or a laminate, in particular an HPL laminate.
  • MDF medium density fiberboard
  • HPL laminate HPL laminate
  • the medium-density fiberboard has a porous structure and is not pressed too tightly. This results in a low weight and also improves the acoustic effect.
  • a laminate is understood to mean 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 the laminate and stands for "High Pressure Laminate", that is, for a laminate that is created by high pressure pressing.
  • the front and or the back of the respective acoustic module has a smooth or structured surface or a pattern. It is particularly advantageous if the orientation of the structure or the pattern of adjacent acoustic modules is different.
  • the acoustics of the room and thus the sound absorption can be further improved and adapted by adapting the surface properties of a respective acoustic module.
  • the acoustic arrangement 1 for sound absorption shown in the drawing has at least two sound-absorbing acoustic modules 2.
  • the respective acoustic module has a plate-like structure and is acoustically effective. It has a front side 3 and a rear side 4, which are connected to one another all around via narrow sides 5.
  • At least one fixed connection 6 is provided on each narrow side 5 of the respective acoustic module 2.
  • at least two fixed connections 6 are provided on each narrow side 5.
  • the acoustic arrangement 1 has a first holding device 7, here a ceiling beam, a ceiling or the like, for fastening at least one acoustic module 2.
  • the first acoustic module 2 can be fastened to the first holding device 7 by means of a fastening device 8 via the at least one stationary connection 6 of a narrow side 5. When fastened, a first acoustic module 2 hangs from the holding device 7 in a vertical orientation.
  • a narrow side 5 of the first acoustic module 2 facing away from the first holding device 7 and a narrow side 5 of at least one further acoustic module 2 are arranged opposite and spaced apart from one another in the assembled state. Furthermore, the first acoustic module 2 and the respective further acoustic module 2 are connected to one another via the connections 6 of the opposite narrow sides 5 by means of a fastening device 8.
  • Such a hanging modular acoustic arrangement 1 increases the flexibility in the design of, for example, office spaces. This not only has a positive influence on the acoustics of a room, but can also divide the rooms at the same time without taking away their spaciousness.
  • At least one further acoustic module 2 is arranged horizontally adjacent to the first acoustic module 2.
  • the respective further acoustic module 2 can be fastened to the first holding device 7 by means of a fastening device 8 via a narrow side 5.
  • At least one further acoustic module 2 is arranged vertically adjacent to the respective further acoustic module 2.

  • a rigid connecting means 10 in particular a rod or a bolt or a sleeve, is provided.
  • connection 6 or the connections 6 on each narrow side 5 of a respective acoustic module 2 is the same. This enables a simplified assembly, since the arrangement of the connections 6 and thus the assignment to a further acoustic module 2 is independent of the side.
