Abstract
Es wird ein Schalldämpfungselement vorgestellt, das aus einem luftreinigenden und schalldämpfenden Schafwollvlies (1) besteht, an dessen Außenseite ein akustisch wirksames Dekor-Material (3) und an dessen Innenseite eine poröse Dämmplatte aus Hanffasern (2) anliegt. Es kann entweder in einer schachtelartigen Kassette (4) gleicher Größe mit schallhartem Boden und stabilisierenden Seitenwänden eingebaut werden, wobei das Dekor Material entweder ein die Kassette (4) einhüllender akustisch wirksamer Stoff, oder ein mit den Kassettenwänden verbundenes, akustisch perforiertes Hartmaterial sein kann. Andererseits kann das Dekor-Material ein gelochtes Blech (3a) sein, welches das schalldämpfende Element mit seinem umgekantetem Rand (3b) umfasst und stabilisiert, sodass durchdringende Schallwellen gedämpft werden. Mit den vorgestellten Schalldämpfungselementen lassen sich neben architektonisch hochwertig gestalteten Anordnungen an Oberflächen und Wänden auch schalldämpfende Schränke bauen, wobei der Sockel (10) und die Türen (16) und Frontblenden aus gelochtem Blech mit umgekanteter Stabilisierung gefertigt sind und die Seitenhäupter (13) und gegebenenfalls die Rückwand (14) mit Kassettenelementen verkleidet oder in diese integriert sind.It is a sound damping element presented, which consists of an air-purifying and sound-absorbing sheep wool fleece (1), on the outside of an acoustically effective decorative material (3) and on the inside of a porous insulation board made of hemp fibers (2). It can be installed either in a box-like cassette (4) of the same size with a hard-sounding bottom and stabilizing sidewalls, the decor material being either an acoustically active material enveloping the cassette (4) or an acoustically perforated hard material connected to the cassette walls. On the other hand, the decorative material may be a perforated plate (3a), which comprises and stabilizes the sound-absorbing element with its folded edge (3b), so that penetrating sound waves are damped. With the proposed sound attenuation elements can be next to architecturally high-quality arrangements of surfaces and walls also build sound-absorbing cabinets, the base (10) and the front panels (16) and perforated plate with folded edge stabilization are made and the Seitenhäupter (13) and optionally the rear wall (14) covered with cassette elements or are integrated in this.
Description
Moderne Immobilien weisen glatte Wände, viel Glas und glatte, reinigungsfreundliche Böden auf. Erfolgt die Einrichtung der Aufenthaltsräume wiederum mit glatten, reinigungsfreundlichen Möbeln, erhält man eine äußerst unangenehme Akustik mit langen Nachhallzeiten, welche konzentriertes Arbeiten oder die Kommunikation sehr erschwert.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.
Deshalb sind in Normen wie z. B.
Weist die Baulichkeit bezüglich Akustik und Ökologie Mängel auf, können physiologische Verbesserungen vor allem durch geeignete Einrichtungsgegenstände und Ausstattungen herbeigeführt werden. Solche Schalldämpfungsmaßnahmen sind oft allgemein bekannt wie etwa der Einsatz poröser Oberflächen und Textilien. Es gibt aber auch speziell für Aufenthaltsräume entwickelte Schall absorbierende Einrichtungen und Geräte, etwa abgehängte Schallschutzdecken oder im Raum angeordnete Schallabsorber an Decke oder Wand, oder auch als spezielle Konstruktionen. Angaben über die Schalldämpfung der Einrichtungen und Geräte sollen deren sinnvollen, effizienten und kostengünstigen Einsatz planbar machen, um nicht auf Zufall und Intuition angewiesen zu sein. Das geschieht vor allem über die Wirkungseffizienz und wirksame Oberfläche der Elemente, denn es kann nur der Schallanteil gedämpft werden, der auf ein Element trifft. So muss in der Regel ein erheblicher Anteil der Raum-Oberfläche oder eine adäquate Ersatzfläche für Schalldämpfungsmaßnahmen zur Verfügung gestellt werden, wobei der Fußboden und Fensterflächen schon von vornherein ausscheiden.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.
Auf dem Gebiet der Reduktion von Geruchsbelästigungen sind neben schon länger bekannten und geschützten künstlichen Textilien in den letzten Jahren Vliese aus reiner Schafwolle bekannt geworden, welche häufige Schadstoffe wie etwa Formaldehyd im Wesentlichen durch katalytische Wirkung in geruchslose Substanzen wie CO2 oder Wasserdampf umwandeln und sich deren Wirkung daher über Jahrzehnte nicht verbraucht. Sie können ihre Wirkung nur voll entfalten, wenn auch eine Luftströmung über oder durch das Vlies erfolgt. Hierdurch wird gleichzeitig auch eine schalldämpfende Wirkung erzielt.In the field of the reduction of odor nuisance in addition to already known and protected artificial textiles in recent years fleeces made of pure sheep wool have become known, which convert frequent pollutants such as formaldehyde essentially by catalytic action in odorless substances such as CO2 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.
Die reinigende Wirkung von Schafwolle ist bekannt, sie wird unter anderem in
Seit kurzem sind im Baugewerbe Dämmplatten aus Hanffasern in Verwendung, welche eine hervorragende Wärmedämmung auf natürliche, ökologische Weise erzielen. Diese Platten sind auch bezüglich Schalldämpfung höchst wirkungsvoll einsetzbar, ähnlich der häufig eingesetzten Mineralwolleplatten, aber ohne deren Staub und Juckreiz verursachenden Eigenschaften. Überdies besitzen sie eine recht gute Stabilität.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.
Schalldämpfende Einrichtungen für viele Lärmquellen sind schon länger bekannt. Auch für akustisch höherwertige Räume sind verschiedene Absorber und Spezialmaterialien entwickelt worden, die bekanntesten sind Schaumstoffpyramiden und schalldämpfende Deckensysteme mit porösen Platten, aber auch mobile Systeme, zumeist in quaderförmiger Bauweise mit speziellen Absorptionsmaterialien in bestimmter Anordnung.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.

Die Erfindung kombiniert nun die Dämmplatte aus Hanffasern mit einem luftreinigenden und schalldämpfenden Schafwollvlies und einer akustisch wirksamen Hülle zu einem auch ökologisch überzeugenden, effizienten Schalldämpfungs- und Luftreinigungselement, dadurch gekennzeichnet, dass ein Vlies aus Schafwolle mit der inneren Seite unmittelbar an eine poröse Dämmplatte aus Hanffasern und mit der äußeren Seite an ein akustisch wirksames Dekor-Material grenzt.The invention now combines the insulation board 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 cleaning 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.
Die Schafwolle liegt damit an der Stelle größter Luftschwingungen bzw. Luftbewegungen und kann so Ihre reinigende Wirkung am besten entfalten.The sheep's wool is thus at the point of greatest air vibrations or air movements and so can develop your cleansing effect best.
Die Eignung und Ausführungsweise der Hanffaserplatten für akustische Zwecke wurde in vielen Anordnungen und Messungen ermittelt. Sie weist dabei ähnliche Eigenschaften wie andere Faserstoffe, vor allem Mineral- oder Glaswolle auf, welche vor allem wegen ihrer geringen Kosten und guter akustischer Wirkung sehr häufig eingesetzt werden, aber wegen ihrer physiologischen Eigenschaften, vor allem Stauberzeugung und Juckreiz durch Faserbruch in Verruf gekommen sind und in Innenräumen manchmal nur mehr staubdicht in Folie eingepackt verwendet werden dürfen, was zwar thermisch irrelevant ist, aber einen sehr negativen Einfluss auf deren Schallabsorption hat.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 fibers, 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 fiber break in disrepute indoors and indoors may only be used more dust-tightly wrapped in foil, which is thermally irrelevant, but has a very negative impact on their sound absorption.
Handelsübliche Dämmplatten aus Hanffaser sind physiologisch völlig unbedenklich. Sie können darüber hinaus herstellungsbedingte, unregelmäßig verteilte Faserverdickungen bzw. Faserknoten aufweisen, welche ähnlich der in
