Definitions

  • the invention relates to a device system for influencing the room acoustics, a piece of furniture for such a device system and a method for influencing the room acoustics.
  • the quality of a room d. H. its suitability for the intended purpose (living, work, training, etc.) also depends significantly on its acoustic properties. Depending on the purpose of a room, different requirements are placed on them.
  • the reverberation time a central parameter for characterizing the room acoustics, should usually be greater, for example, in a church than in a concert hall or even a work, living or training room.
  • the acoustics of a room are first determined by the geometry of the room and the materials used for the floor, walls and ceiling. Further influences result from the room design and also by people in the room.
  • the reverberation time should not exceed a certain value (usually between 0.6 and 1.0 s), in particular in a frequency range of approximately 250 to 2000 Hz.
  • the reverberation time is also different without acoustic optimization in common rooms for different frequencies, which causes certain frequency ranges to linger longer relative to others and thus the timbre changes temporally. Such frequency-dependent differences should also be reduced to an acceptable level.
  • the furnishing elements can primarily perform two tasks, namely to absorb the sound and / or to redirect it.
  • the use of flat absorber elements in the manner of panels, which are mounted in the wall and / or ceiling area, is known and primarily have the task of absorbing sound and thus reduce the reverberation time overall.
  • acoustic room dividers which are placed free-standing in the room and also can have a sound-directing effect.
  • the known wall and ceiling panels can not be integrated in any room with sufficient effective area, for example, because large wall surfaces are covered by directly in front of standing furniture, because large windows are present or because the absorber difficult in the interior design of the room or the lighting concept integrate.
  • the known room dividers (partitions) require additional parking space and thus reduce the usable space area, they can not be placed in their acoustically optimal arrangement but are primarily subordinated to the functional division of space. It has also been shown that with the known means the problem of timbre changes can only be gotten under control with great effort.
  • the object of the invention is to provide a technical system belonging to the aforementioned technical area, which can be in a variety of rooms, especially in offices, work, work training and living spaces, integrate, saves space and a significant improvement in room acoustics , especially with regard to the reduction of timbre changes possible.
  • the furnishing system comprises at least one piece of furniture having a substantially cubic shape with four vertical side surfaces, a horizontal bottom and a horizontal ceiling, wherein at least two, preferably at least three, of the side surfaces for sound absorption are modified and arranged such that a sound absorption coefficient of the Furniture in a frequency range between 150 and 400 Hz assumes its maximum.
  • the furnishing system also comprises at least one planar Sound absorber for increasing the sound absorption in a frequency range of over 400 Hz.
  • the furnishing system thus includes complementary elements whose acoustic properties complement each other.
  • the basic frequency of human speaking voices lies, so it comes to him in the optimization of room acoustics in offices, work, work training and living spaces in which people are and communicate with each other, make phone calls, listen to the radio or watch TV a great importance too.
  • Investigations have now shown that just sound emissions in this frequency range are usually not sufficiently damped by conventional room facilities.
  • the reverberation time in this frequency range is too large, the room is perceived as noisy and speech intelligibility is impaired.
  • the attenuation is greater, which leads to a shift of the noise spectrum in the low-frequency range and thus to tone color changes.
  • Even conventional flat sound absorbers such as ceiling or wall absorbers, acoustic panels, carpets, curtains, etc., have their absorption maxima mostly in a range of over 400 Hz.
  • the inventive device system now the sound absorption in the low frequency range is supported by the specified, especially in the lower frequency range sound-absorbing furniture.
  • the two-dimensional absorbers arranged primarily at the room boundaries (floor, walls, ceiling) and the body (s), possibly distributed in the room, complement each other, so that a good and, as far as possible, frequency-independent sound absorption in the frequency range of interest from about 150 to about 2500 Hz can be achieved.
  • said furniture or more such furniture are arranged such that a desired sound absorption in a frequency range of 150 to 400 Hz is achieved, and in addition at least one planar sound absorber is arranged such that a desired sound absorption in a Frequency range of over 400 Hz is achieved.
  • the planar sound absorber is preferably a panel that can be fastened to a room ceiling or a room wall. Such panels are known and allow high sound absorption at frequencies of 400 Hz and more.
  • the sound absorption in this area is perceived by sound-absorbing planar room partitions (acoustic standing panels), by floor coverings, ceiling or wall elements and / or flat textiles (eg carpets, curtains).
  • the modified side surfaces of the inventive furniture are advantageously designed as perforated plates, in particular as perforated plates, with a hole diameter of at least 2 mm and a perforation of at least 20%, wherein on at least one side of the perforated plates a pulp of a porous material with a Thickness of a maximum of 1 mm is arranged. It has been found that such a combination allows a high sound absorption even at low frequencies, but at the same time is well suited for the furniture side surfaces in terms of stability, handling and aesthetics.
  • perforated plates in terms of aesthetics, stability and handling are particularly advantageous perforated plates, but it are also perforated plates made of wood or plastic.
  • perforated plates In comparison with so-called "micro perforations" in which the hole diameter is usually only about 0.5 mm and the degree of perforation (ie the ratio between the sum of the hole areas and the total area) is significantly lower, significantly lower production costs result with equivalent sound insulation in the frequency range of interest .
  • the thin fiber allows for aesthetically pleasing furniture design compared to other higher-absorbency sound-absorbing materials (eg, foams) and requires no or at most minor design adjustments to existing furniture designs. It is also easy and easy to process, for example, it can be glued to the perforated plate large area.
  • the pulp is arranged only on the inside of the perforated plates, while the outside of the perforated plates is uncovered.
  • the more stressed outside is thus comparatively resistant and easy to clean perforated plate, z. B. formed by a perforated plate, while the pulp is protected on the inside by the perforated plate of actions.
  • the pulp is arranged in addition or exclusively on the outside of the furniture. It is also possible to arrange the pulp differently at different side surfaces of the same piece of furniture.
  • a fibrous material which consists of cellulose and / or glass fibers embedded in a synthetic resin matrix and preferably has a thickness of 0.1-0.4 mm.
  • a corresponding material is z. B. under the name "SoundTex” by the company Freudenberg, Weinheim, Germany. It has a thickness of only 0.2 mm, but due to its porous material structure it absorbs great sound energies and, in the context of the furniture according to the invention, is particularly well suited for achieving the high sound absorption in the range 150-400 Hz.
  • the material can be easily, quickly and permanently attached to the perforated plate, in particular to a perforated plate, thanks to a coating with hot-melt adhesive.
  • the hole diameter is advantageously between 3 and 8 mm and the perforation between 25 and 50%. This results in perforated plates, which allow in conjunction with the pulp high sound absorption, are inexpensive to produce and give the furniture sufficient stability.
  • the concrete values of the hole diameter and the degree of perforation to be selected depend in particular on the material used for the perforated plate.
  • the furniture has a grid-like structure, which is formed by interconnected struts, wherein the side surfaces formed by the perforated plates are held between the struts.
  • the struts also provide the structural stability of the furniture, so that the side surfaces can be designed for optimal sound absorption.
  • the lateral plates can in particular have a small thickness and an acoustically optimal degree of perforation.
  • one of the side surfaces of the furniture may be formed by an openable door, wherein the door is not modified for sound absorption.
  • the door may in particular be a folding, extending or sliding door. It has been shown that the modification of three side surfaces is generally sufficient to achieve a high level of sound absorption and the additional modification of the door does not disproportionately increase the degree of absorption.
  • a door which is conventionally designed can be produced significantly less expensively than an acoustically modified one (which comprises, for example, a perforated plate and a nonwoven fabric), in particular if the door has to be mechanically stable, for example in order to serve as a shelf in the unfolded state.
  • the door may also be modified for sound absorption. It is constructed in this case, for example, of two perforated plates connected in parallel to each other, on the mutually facing inner sides of the acoustic fleece is attached. Measurements have shown that a completely modified furniture shows a good sound absorption contrary to expectations, so that it is not sound transparent as it were, despite the double-sided perforations.
  • the depth of the furniture used in the invention is advantageously between 20 and 60 cm.
  • such furniture not only work with individual areas, such. B. with their faces, sound absorbing but as a body and thus act complementary to planar sound absorbers.
  • FIGS. 1A, 1B show schematic exterior views of furniture according to the invention.
  • FIG. 1A shows a piece of furniture 1 which is part of a furniture system and is composed of six elements 1.1. Each of the elements is cuboid and has the dimensions 750x395x375 mm (WxHxD). The dimensions of the shown furniture 1 are 1525x1092x375 mm (WxHxD).
  • the furniture 1 comprises a grid-like structure, which is formed by chromed steel tubes 2, which are screwed to the corner and node points with chromed brass balls 3. Between the chromed steel pipes 2 lining elements 4 are attached from powder-coated metal sheet. On the vertical front sides of the elements 1.1...

  • the vertical side surfaces of the furniture 1, 5 right and left and rear, d. H. the rear wall and the side walls, are provided with cladding elements, which are formed by perforated plates, on which inside a sound-absorbing fleece is glued.
  • FIG. 2A shows a schematic view of a perforated plate 6 for a side surface, with only the respective outermost rows of the perforation being shown in favor of a clearer representation. However, the perforation continues within the rows shown with the same hole size and the same hole spacing, so that the entire outer surface of the sheet is perforated uniformly.
  • the holes 7 are round and have a diameter of 5 mm, the centers of adjacent holes 7 of a row have a distance of 10 mm. Adjacent rows have a spacing of 5 mm, their holes 7 are each about half the hole spacing, d. H. offset by 5 mm. This results in a perforation of about 30%, d. H. the sum of the hole areas is 30% of the entire flat sheet surface.
  • the sheet 6 shown in FIG. 2A is folded inwards in its edge regions, as shown schematically in cross section in FIG. 2B. It thus forms a suitable receptacle for the steel tubes 2 of the furniture structure and can be held between them.
  • the fleece 8 is glued on the inside of the sheet. Its area corresponds approximately to the area of the flat area of the sheet 6, the holes 7 are thus all covered on its inside by the web 8.
  • the fleece 8 consists of cellulose and glass fibers, which are bound by means of synthetic resin.

  • the equivalent acoustic sound absorption area A is a measure of the absorption effect of materials in the room and allows a direct comparison between different, especially between flat and physical, sound absorbers. It corresponds to an ideal equivalent absorber area, where an ideal absorbent is a (hypothetical) material that is 100% absorbent at all frequencies and does not produce reflections ("open window"). It should be noted that the reverberation time T rev and thus also the equivalent acoustic sound absorption area A are dependent on the frequency f of the sound emission.
  • the reverberation chamber with a volume of 214 m 3 used for the measurements has reverberation times of approx. 20 s at 100 Hz and of approx. 2 s at 5'000 Hz, the two limit values of the frequency range recorded during the measurement.
  • the reverberation time T rev of the empty reverberation space was measured at frequencies of 100 Hz to 5,000 Hz with third octave jumps at 100, 125, 160, 200, 250 ... 5,000 Hz.
  • white noise was used as sound emission, after interruption of the emission the measurement of the acoustic level took place evenly with ten In the room distributed precision microphones, so that the respective reverberation time could be determined.

This has advantages in that the formation of the door with perforated plates and fleece causes significantly higher costs than the modification of the side walls or the rear wall. As can be clearly seen, although a somewhat lower sound absorption results, the basic character with a maximum sound absorption in the range of 160 to 315 Hz is unchanged compared to the maximum variant. In this frequency range, the reduction of the equivalent sound absorption area A due to the lack of modification of the door is about 16%, while at higher frequencies it is about 38%.
