    Soundproofing selement
    Modern properties have smooth walls, lots of glass and smooth, clean-friendly floors. If the rooms are furnished with smooth, easy-to-clean furniture, the result is extremely unpleasant acoustics with long reverberation times, which makes concentrated work or communication very difficult.
    Therefore, in standards such as DIN 18041 already established specifications for good or usable acoustics in various lounges, which are usually far missed without targeted acoustic measures. Often, the building biology is neglected and it is often because of the prevailing rules and interests (ease of cleaning, insensitivity, fire protection, hygiene, etc.) materials, especially textiles used, which are not free from evaporation. The use of the premises with a high occupancy rate and visitor traffic, which is usually more intensive than private living, also leads to unpleasant odors, which must be compensated for by increased fresh air throughput and thus more energy expenditure in ventilation, heating and air conditioning.
    If the building has defects with regard to acoustics and ecology, physiological improvements can be brought about, above all, by suitable furnishings and equipment. Such soundproofing measures are often well known, such as the use of porous surfaces and textiles. But there are also specially designed for lounges sound absorbing equipment and devices, such as suspended soundproof ceilings or arranged in space sound absorbers on ceiling or wall, or as a special constructions. Information about the sound attenuation of equipment and devices should make their meaningful, efficient and cost-effective use predictable, so as not to rely on chance and intuition. This happens above all through the effect efficiency and effective surface of the elements, because it can only be damped, the sound content that strikes an element. As a rule, a significant proportion of the room surface or an adequate replacement area for soundproofing measures must be made available, with the floor and window areas exuding from the outset.
    In the field of reduction of odor nuisance in addition to already known and protected artificial textiles in recent years fleeces made of pure sheep's wool have become known, which convert frequent pollutants such as formaldehyde essentially by catalytic action in odorless substances such as C02 or water vapor and their effect therefore not consumed for decades. They can only fully develop their effect, even if an air flow over or through the fleece takes place. As a result, a sound-absorbing effect is achieved at the same time.
    The cleansing effect of sheep wool is known, it is described inter alia in W09944724A1 (Doppelmayer) and has since been documented by numerous reports and experiences, although not completely clarified.
    Recently, in the construction industry, hemp fiber insulation boards are in use, which achieve excellent thermal insulation in a natural, ecological manner. These panels are also highly effective in terms of sound attenuation, similar to the commonly used mineral wool panels, but without their dust and itching causing properties. Moreover, they have a fairly good stability.
    Sound-absorbing devices for many noise sources have been known for some time. Various absorbers and special materials have also been developed for acoustically superior rooms, the most well-known being foam pyramids and sound-damping ceiling systems with porous panels, but also mobile systems, usually in cuboid design with special absorption materials in a specific arrangement.
    For example, DE2437947A1 (Kurtze) proposes different layers, at least one of which is closed-cell flexible foam with embedded mass particles. DE 102007000568Al (SilenceSolutions) shows a layered construction of plate materials of widely differing acoustic impedance with at least 20 kg / m3 density difference, without air between the layers and with at least two different impedance jumps, preferably PUR foams. Behind the entrance surface is denser material, behind permeable material arranged. By a suitable design, the sound is well absorbed even when hitting the side walls. GB2459676A (Itze) generally stimulates sound absorption and damping structures made of natural and ecological materials such as hemp, sheep's wool, coconut fiber, recycled cotton wrapped in acoustically permeable membranes or fabric, regardless of construction. WO2013167383A1 (SilenceResearch) preferably describes T-shaped partitions whose free edges are designed as all-sided absorbers. The surfaces may preferably be made of glass for better exposure. The absorbers are widely around the aluminum profile frame of the elements arranged around perforated sheets filled with porous material and attenuate especially the diffraction of airborne sound around free edges.
    The AT508797B1 (Blaha) describes a two-part sound-absorbing cuboidal element that can be opened and whose two halves are variably equipped with a variety of acoustically effective plate materials and can be changed after installation in their impact properties and adapted to the room needs. Also mentioned is the supporting effect of the functional gap between two elements, as well as the air purifying effect of sheep wool fleece.
    The AT511957A4 (Blaha) describes furniture, in particular seats made of a perforated support structure with an acoustically effective shell, whose interior contains sheep's wool inserts for air purification, without special arrangement requirements. The bottom gap serves for better air exchange.
    The invention now combines the insulation board made of hemp fibers with an air-cleaning and sound-absorbing sheep wool fleece and an acoustically effective shell to an ecologically convincing, efficient Schalldämpfungs- and air purification element, characterized in that a fleece of sheep wool with the inner side directly to a porous insulation board of hemp fibers and borders with the outer side of an acoustically effective decor material.
    The sheep's wool is thus at the point of greatest air vibrations or air movements and so can develop your cleansing effect best.
    The suitability and execution of the hemp fiber plates for acoustic purposes has been determined in many arrangements and measurements. It has similar properties as other laser materials, especially mineral or glass wool, which are mainly used because of their low cost and good acoustic effect, but have come because of their physiological properties, especially dust production and itching by laser fracture in disrepute and indoors sometimes only dust-proof in Lolie packed may be used, which is thermally irrelevant, but has a very negative impact on their sound absorption.
    Commercially available hemp fiber insulation boards are physiologically completely harmless. They can also have manufacturing-related, irregularly distributed fiber thickening or fiber knots, which develop their damping effect similar to the mass particles described in DE2437947A1 (Kurtze). However, the very good sound-damping effect is also explained by the lower flow resistance in the direction of the plate extension in relation to the plate, which favors the scattering of sound waves arriving perpendicular to the plate in the material. Also in terms of fire and insect infestation is a great resistance. Overall, this hemp fiber insulation boards have a much better property spectrum compared to the previously used absorber materials. The specified in the labeling design of sound absorbers is thus a novelty and a technical and physiological improvement.
    The invention will now be explained in several figures.
    Fig. 1 shows an embodiment of the invention in cross section and descriptive, Fig. 2 shows another expression in cross section and descriptive, Fig. 3 shows a third expression in section and Fig. 4 shows an application of the three characteristics in a cabinet furniture in vertical and horizontal section, as well as descriptive.
    Fig. 1 shows the fleece of sheep's wool 1, which rests with its inside on an insulating panel of Hanffasem 2 and with its outside on an acoustically effective decorative material 3 and thus forms the sound-damping element according to the invention. In this embodiment, it is in a box-like cassette 4 with a reverberant cartridge bottom 4a and side walls 4b, which may have openings 4c to provide laterally incident sound less resistance. The decor material 3 is an acoustics fabric with defined transmission parameters that is stretched outwardly around the side walls 4b and attached to the edge of the cassette bottom 4a so that the components are held together. The cassette material may e.g. a hardboard, which is bent along milled grooves into a box and held by the acoustic fabric 3 in the form. As well, the cassette 4 can also be formed from a base plate with circumferentially fixed, perforated angle profiles or fiberboard strips. Alternatively, instead of the acoustics, a thin hard but perforated plate, e.g. a hardboard or perforated plate placed and connected to the side walls 4b.
    Fig. 2 shows the same sound attenuation element 1, 2, 3 adjacent to an equally large stable furniture panel 5, in particular a Dekorspanplatte, but also veneer, plywood or other types of boards used in furniture. The arrangement is bordered by accurately fitting, perforated thin-walled U-profiles 6, which ensure cohesion and edge stability and by their perforation also engage laterally impinging sound waves. The outer decor material is again acoustic fabric, which is sewn together to form a matching shell, pulled over the entire assembly and attached to the edges of the furniture panel 5. This design with integrated furniture panel allows, for example, the immediate use in furniture construction.
    FIG. 3 shows a cross-section of a sound-damping element according to the invention, which has a perforated sheet 3a as decorative material. It is circumferentially folded over to a frame 3b, which surrounds or stabilizes the sound-damping element 1, 2. This element is pre-set at a distance 7 in front of a reverberant wall 8, wherein the size of the distance 7 as is known for the depth of the frequency range to be absorbed is relevant. The acoustic effect corresponds to a suspended metal ceiling with damping liner.
    In Fig. 4, a sound-absorbing cabinet is shown, which is constructed from previously described elements. Under the bottom of the cabinet 9 is a base 10 made of sheet steel, the front of which forms the perforated decorative material 3a for the sheep wool fleece 1, behind an insulating plate of hemp fibers 2 is arranged. Another steel profile at the back forms with the bottom of the cabinet 9, the bottom 12 and the side heads 13 a cassette 4. The base is about supports 11 on the floor 12. The side heads 13 are executed according to Fig. 2, the integrated furniture panels 5 form Dowelling with the bottom plate 9, the rear wall 14 and the cover plate 15, the cabinet body, the inside of which is completely identical to a standard cabinet and therefore can be provided as well with shelves, extracts or store. The doors 16 are made of perforated metal sheet with an edged frame 3b according to FIG. 3, with integrated sound damping element 1, 2, 3a. They are fixed with standard door hinges 17 and are used instead of standard doors.
    If the cabinet is free in the room, a suitable sound attenuation element 18 according to FIG. 1 can be fastened to the rear wall 14.
    The interior 19 is involved by the sound-absorbing, permeable doors 16 on the sound attenuation, the rear wall 14 forms in the empty cabinet the reverberant
    Surface, depending on the contents of the cabinet, different depths are formed and thus dampen a wealth of different, especially low sound frequencies.
    If the cover plate 15 is not used as a tray, it can also be formed as shown in FIG. 2 as the Seitenhäupter 13. Instead of doors 16 as well as front panels for extracts and store can be built, thus resulting in the same design options as before.
    But it can also standard cabinets be upgraded acoustically by replacing the doors and front panels and side heads and free back walls are covered by Schalldämpfungskassetten shown in FIG.
    The sound attenuation elements can be fastened in any desired way to free surfaces, in particular in the embodiment according to FIG. This can be created with different sizes, thicknesses and decors an architecturally or artistically sound-absorbing structure.
    If no usable surfaces are available, the elements can also be mounted back to back, either freely in the room, or mounted on a frame that stands free as a room divider.
