Definitions

  • the present invention relates to a room unit with the features of the preamble of claim 1.
  • acoustic signals such as music or speech performances
  • sound carriers e.g. Magnetic tapes, vinyl records or CD's specially designed and appropriately constructed and furnished recording studios are used. Because of the relatively expensive production price of such recording studios, these are generally only available from larger broadcasting companies or from manufacturers of recorded or discussed sound carriers. This in turn means that these recording studios are occupied for a long time and their rental price is correspondingly expensive.
  • the invention has for its object to provide a room unit of the type specified, which allows the recording and / or reproduction of acoustic signals in a particularly simple manner, with special attention to the recording and / or playback quality.
  • the invention is based on the basic idea of recording and / or reproducing acoustic signals on and / or sound carriers in a room unit designed as a portable room cell.
  • the room cell designed according to the invention is either set up in closed rooms or outdoors, with recording and / or playback devices for the acoustic signals arranged in the interior, which are, for example, music, speech or the like. acts, has.
  • the room cell Due to the special shape of the room cell, which is designed as a sphere, regular, sphere-like polyhedron or a part thereof, optimal acoustic conditions are made possible, which are expressed in an excellent recording and / or reproduction quality of the acoustic signals to be recorded or recorded. This is attributed to the fact that, due to the special shape of the boundary surfaces of the room cell, a natural sound field, which radiates from all sides to the respective user, is generated, which consists of an ideal mixture of direct sound, diffuse sound and sound resonances.
  • the spatial unit according to the invention is used for the recording of acoustic signals on sound carriers, the signals recorded in this way have a richness of detail, sound balance and a natural auditory spatiality.
  • the room unit designed according to the invention once again offers richness of detail, sound neutrality and natural auditory spatiality, i.e. conditions that enable reproduction that is true to the original in all respects and can only be compared to complexly constructed and equipped sound studios are or even surpass them.
  • the room unit also has other advantages. It switches off all external noise, such as street noise, noise from neighboring rooms, or the like and at the same time prevents noises from the inside of the room cell from reaching the outside.
  • the room unit designed according to the invention can thus be used ideally for samples, for example of bands or soloists, whose noise development is often disrupted by roommates. It also allows a completely encapsulated listening to acoustic signals stored on sound carriers, such as music, so that they are excellent for the acoustic comparison of various playback devices, such as stereos, or for listening to recorded music, such as records, compact disks usually z. Are currently being listened to over the head, which is often perceived as disturbing, can be used.
  • the room unit designed according to the invention for tuning instruments, such as high-quality concert grand pianos or stringed instruments, but because of the easy transportability of the room cell, it only has to be set up over the concert grand piano to be tuned, so that such an expensive and heavy instrument is not must be transported. It is also possible with the room unit to teach several soloists in a room at the same time, it being only necessary for this that a number of room cells corresponding to the number of soloists is arranged in this room.
  • the spatial unit also allows completely new sound carriers to be produced in terms of richness of detail, sound balance and auditory space.
  • individual soloists and / or soloist groups are each located in a room cell and the music that is produced from them under optimal acoustic conditions is fed to the recording device via corresponding mixing devices, so that a reproduction of those recorded in this way
  • Pieces of music lead to results that are characterized in particular by the sharpness of location and depth of the individual instruments or instrument groups and an excellent spatiality, so that a playback quality is achieved that corresponds to a live concert in a large cathedral with excellent acoustics, without the disturbing background noises always appear at such a concert.
  • the recording is checked in a room unit and reproduced later, even lossless transmission is guaranteed.
  • the spatial cell has the shape of a truncated cone or a truncated polyhedron. If the spatial cell is designed as a cut sphere, a position is preferably selected for the cutting plane that is below the center of the sphere, so that a spatial cell is created that is larger than a hemisphere.
  • the above-described sound field which is responsible for the excellent acoustic properties of the room cell, concentrates on a central area of the spherical section, the central area depending on the size of the respective spherical section being about a fifth to about two thirds of that Height of the spherical section and extends approximately to the same extent over the diameter of the cut surface of the spherical section.
  • the middle area With increasing size of the spherical section, the middle area also increases, so that in the case of large-volume room cells, which serve in particular to accommodate a larger number of people, correspondingly large sound fields are also available.
  • a preferred embodiment of the room unit provides that the room cell has the shape of a cut icosahedron.
  • the icosahedron is cut off in such a way that it has a regular pentagon as the base surface, while the other polygon surfaces consist of equilateral triangles.
  • the edge length of the regular pentagon corresponds to the side length of the equilateral triangle.
  • a room cell designed in this way is particularly well suited for the recording and / or reproduction of the acoustic signals, since due to the special arrangement of the polygon surfaces these are reflected particularly well in a central region of the room cell, so that sound fields arise here, both during recording as well as when reproducing the user or the users cause an optimal spatial sound.
  • such a room cell still has a good appearance, so that it can be easily integrated into a living room without being perceived by the occupant as annoying.
  • the recording and / or playback devices for the acoustic signals are expediently used in the middle area in which the sound field is concentrated.
  • An arrangement of the recording and / or playback devices in the upper third of the middle region is particularly suitable, since the best results can be achieved by such an arrangement according to the present investigations.
  • a further embodiment provides for the icosahedron section described above to be vertical to cut to the base surface that a hexagonal base is formed with a rectangular wall section which, with the exception of the rectangular wall section and the two immediately adjacent triangular surfaces adjacent to it, has the shape of the icosahedral section described above.
  • the rectangular wall section serves to receive a door element that extends entirely or partially over the wall section.
  • two or more door elements can also be arranged in the horizontal, rectangular wall section. As the studies show, the arrangement of such a horizontal wall section essentially does not change the acoustic conditions within the room cell.
  • a special embodiment has a door element located in the rectangular wall section, which continues to follow extends into the equilateral triangle arranged above the door element and covers an area thereof. This ensures that the door element has a passage height of about 200 cm, which would not be ensured because of the living space height of about 250 cm usually present in living rooms in an embodiment in which the door element only extends over the height of the rectangular wall section. Such an expansion of the door element changed upwards the acoustic conditions of the room cell are not.
  • the space unit designed according to the invention is preferably easy to assemble or disassemble, so that it can be erected at any location with relatively little means. If it is to be set up, for example, within an apartment, a base area or slab can generally be dispensed with, since the floor takes over the function of the base area or slab. It is of course also possible to provide the room unit with a corresponding base area, which creates a room cell that is closed on all sides.
  • the base area is preferably designed as a base plate.
  • the room cell has a frame, the struts of which consist, for example, of appropriately shaped metal profiles.
  • the struts are connected to one another at their contact surfaces, for example by means of screws, interlacing or the like.
  • Suitable surfaces, preferably correspondingly shaped plates, are arranged between the struts of the frame and are attached to the Struts of the frame are attached.
  • the individual surfaces from which the spatial cell is formed each have strip elements on their edges, which extend partially or completely over the length of the edges.
  • the individual surfaces for assembling the room cell are connected to one another via connecting elements arranged on the strips, such a room cell thus having a self-supporting construction.
  • a particularly preferred embodiment of the room unit has connecting elements which can be connected to one another by clamping engagement, so that such a room unit can be assembled and disassembled easily and quickly without the use of tools.
  • These connecting elements are preferably designed as one-sided narrowing recesses in the strips, so that adjacent surfaces of the room cell are connected to one another via bolts which are in clamping engagement with the narrowed regions of the recesses of the connecting elements.
  • any conventionally used building material such as, for example, plasterboard, particle board, glass, plastic plates, or the like, can be used as the material for the room cell.
  • Particularly good results can be achieved if the room cell is made from panels that are provided with a soundproofing layer on their outward-facing side and a sound-reflecting layer on their inward-facing side, since this shields particularly good external noise sources and inside the room cell excellent acoustics can be achieved, but the resonance properties of the wall surfaces must be matched to the recording and playback units used.
  • the usual materials such as for example foamed plastics, mineral fiber insulation boards or the like, and hardened plastics, glass, metal plates or the like as a sound reflection layer. be used. Of course, however, it is also possible to use panels that only have an outer sound insulation layer or an inner sound reflection layer.
  • This storage device consists of a frame which has the shape of a pyramid provided with curved edges.
  • FIG. 1 shows a first embodiment of the room unit, which has a room cell designated overall by 1.
  • the room cell 1 has the shape of a cut icosahedron, the base of which is a regular pentagon and 15 polygon surfaces 4, which consist of equilateral triangles. Here, only the edges of the polygon areas are drawn for a better perspective representation.
  • Recording and / or playback devices (not shown) are provided within the room cell 1 and are arranged in an area 5 of the room cell 1.
  • the acoustic signals generated or reproduced therein are reflected on a central area of the room cell with formation of an optimal sound field, with this central area depending on the respective size of the room unit being about 30% to about 70% of the volume of the Makes up the room cell.
  • the second embodiment shown in FIG. 2 has a space cell designated overall by 10, which has a hexagonal base area 11, a rectangular vertical wall section 12, two right-angled triangles 13a, 13b and 12 equilateral triangles 14, of which only a few are designated.
  • recording and / or playback devices are also provided in the room cell 10 and are arranged within the room cell 10 in an area which corresponds approximately to area 5 in FIG. 1.
  • two door elements 15 and 16 are provided, the fillings of which are made of glass and thus bring about an exposure of the room cell 10.
  • the door elements 15, 16 extend further upward into the equilateral triangle 14a arranged above and cover an area thereof.
  • the base surface 11 and the surfaces of the triangles 13a, 13b and 14 and 14a each consist of two gypsum boards in the embodiment shown in FIG. 2, the individual surfaces at their edges using strips and connecting elements shown in detail in FIGS. 3 and 4 are connected.
  • a strip element 22 is arranged on each edge of the plates 20 and 21, which has a connecting element 23 formed in one piece with the strip element on its front section.
  • the strip element 22 has two angle sections 24 and 25, which are used to fasten the plasterboards 20 and 21, respectively.
  • a recess 26 is provided which has a lower, narrowed area 26a.
  • the recess 26, 26a and a bolt 27 arranged therein form from connecting elements ment 23.
  • the plates 20 and 21 are arranged at a distance from one another. This makes it possible to provide additional soundproofing material between the panels. Of course, instead of the two plates 20 and 21 shown in FIG. 3, one plate can only be present.
  • the surfaces to be connected to one another are aligned with one another in such a way that their strip elements 22 and their connecting elements 23 abut one another as shown in FIG. 3.
  • the bolt 27 was inserted into one of the connecting elements and brought into clamping engagement with the narrowed region 26a of the recess 26 by moving in the direction of arrow 28 (FIG. 4), so that moving the other connecting element in the direction of arrow 28 brings about a connection of the two surfaces without that a tool is required for this.
  • the connecting element shown in Figure 3 allows a straight connection of surfaces. Is connecting the Areas at different angles are required, so it is only necessary to change the angles ⁇ 1 to ⁇ 4 shown in FIG. 3 accordingly.
  • An embodiment of the spatial cell designed according to the invention which is designed as a cut ball or as a cut polyhedron, has the advantage of better acoustic properties than a design as a solid ball, since resonances form approximately in the middle of the ball. Such resonance formation is avoided with appropriately cut bodies. Such an embodiment is therefore preferred of the solutions proposed according to the invention.
  • the position of the sectional plane is predetermined by the shape of the icosahedron.
  • the cutting plane is arranged in a position corresponding to a comparable icosahedron.
  • both the recording and the playback devices are arranged centrally within the spatial cell.
  • the recording devices are arranged approximately in the center, but the playback devices are each arranged at the same distance from the center within the spatial cell.
  • the imaginary center of the spatial cell or the cut sphere or the cut polyhedron should be regarded as the center. The distance to be selected depends on the overall dimensions, whereby a corresponding distance from the wall of the room cell must also be maintained.
  • the spatial cell according to the invention is not only suitable for conventional sound carriers, but also for other new media (ISDN system).
  • the frame has hollow struts which are provided with openings.
  • the resulting volume ie. H. the cavity volume of the frame can be used for resonator functions, the openings provided acting as resonator openings. It is particularly expedient to provide these resonator openings in the corners or on the edges of the room cell.
  • the frame or parts thereof thus act as a Helmholtz resonator.
