Description
Die Erfindung betrifft ein Möbelelement mit einer Einrichtung zur Schallabsorption. Derartige Möbel wurden vom Anmelde bereits hergestellt.The invention relates to a furniture element with a device for sound absorption. Such furniture has already been manufactured by the applicant.
Der Zwang zur Immobilienwirtschaftlichkeit hat unsere Arbeitswelt stark verändert. Moderne Ausbaustrukturen sind geprägt durch zunehmend mehr Menschen pro Arbeitsfläche. War vor Jahren der durchschnittliche Flächenverbrauch noch 20 bis 30 m2 pro Arbeitsplatz, liegen wir heute bei 10–15 m2. In hochverdichteten Arbeitszonen werden oftmals 5–10 m2 Arbeitsfläche pro Mensch realisiert. Unausweichlich steigen hiermit die akustischen Lasten. Die Lärmpegel durch kommunizierende und telefonierende Menschen erreichen Größenordnungen im Arbeitsplatzbereich von 65–80 dB.The compulsion to real estate economics changed our working world strongly. Modern expansion structures are characterized by more and more people per working area. Years ago, the average space consumption was still 20 to 30 m 2 per workstation, today we are at 10-15 m 2 . In highly compressed work zones often 5-10 m 2 working area per person are realized. Inevitably, this increases the acoustic loads. The noise levels by communicating and telephone people reach sizes in the workplace of 65-80 dB.
Die Entwicklung wirksamer schallabsorbierender Komponenten erlangt hierdurch zunehmend mehr Bedeutung. Klassische Maßrahmen zur Schallpegelreduktion in Mehrpersonenräumen waren Akustikdecken, Akustikwandverkleidungen, sowie Akustikstellwände. Die Senkung der Lärmpegel mit diesen Komponenten reicht bei flächenintensiv genutzten Gruppen- und Teambüros häufig nicht aus. So hat man in den letzten Jahren zunehmend auch die Fronten und Rückwände der Möbel zur Schallabsorption aktiviert. Der Wirkungsgrad dieser Komponenten ist jedoch sehr begrenzt und in keinem Fall, wie von den Normen gefordert, über das Frequenzband gleichmäßig. Typische Komponenten waren bislang Akustikrolladen, gelochte Holzwände, sowie Lochbleche, welche zur Absorption von Schall mit Vlies und oder Dämmstoff belegt waren. Aufgabe der Erfindung ist es, zusätzliche Schallabsorption bereitzustellen, sowie die aktuelle Forderung der DIN nach gleichmäßiger Absorption mit neuen Maßnahmen zu ermöglichen.The development of effective sound-absorbing components is thereby becoming increasingly important. Classic scale frames for reducing noise levels in multi-person rooms were acoustic ceilings, acoustic wall cladding, and acoustic partition walls. Reducing the noise level with these components is often not enough for area-intensive group and team offices. In recent years, for example, the fronts and rear walls of the furniture have increasingly been activated for sound absorption. However, the efficiency of these components is very limited and in no case, as required by the standards, evenly across the frequency band. Typical components to date have been acoustic roller shutters, perforated wooden walls, and perforated metal sheets which were used to absorb sound with fleece and or insulating material. The object of the invention is to provide additional sound absorption, and to enable the current requirement of the DIN for uniform absorption with new measures.
Erfindungsgemäß wird diese Aufgabe durch die Entwicklung eines neuen Bauteils mit Wirkprinzipien gemäß Anspruch 1 gelöst.According to the invention this object is achieved by the development of a new component with active principles according to
Durch diese Erfindung wird es nunmehr möglich, eine bisher nicht erreichte Variabilität der Akustik zweier benachbarter Arbeitsplätze, zusätzlich zu einer allgemeinen Verbesserung der Raumakustik, zu realisieren. Durch das Koppeln mehrerer Schallabsorptions-Wirkprinzipien in einer justierbaren Schallschutzvorrichtung an einem Kastenmöbel, erreichen die damit generierten Absorptionsgrade eine hohe Breitbandigkeit, welche zu einer Pegelreduzierung zweier benachbarter Arbeitsplätze von nachgewiesenen 20 dB führen. Dies gilt z. B. für 5 m × 5 m große Räume, in welchen eine Akustikdecke mit einem bewerteten Schallabsorptionsgrad αw, von mindestens 0,9, Breitband-Kompaktabsorber in den Raumecken, sowie Akustikmöbel entsprechend vier Ordnerhöhen, schallabsorbierend in einem Frequenzbereich zwischen 100 Hz und 5000 Hz ausgelegt, und in den Ausbreitungsrichtungen Raum-längs und -quer zum Schall vorhanden sind.With this invention, it is now possible to realize a previously unachieved variability of the acoustics of two adjacent workstations, in addition to a general improvement of the room acoustics. By coupling several sound absorption principles of action in an adjustable soundproofing device to a cabinet furniture, the degrees of absorption generated thereby achieve a high bandwidth, which leads to a level reduction of two adjacent workstations of proven 20 dB. This applies z. B. for 5 m × 5 m large rooms in which an acoustic ceiling with a weighted sound absorption αw, of at least 0.9, broadband compact absorber in the corners, and acoustic furniture corresponding to four folder heights, sound-absorbing in a frequency range between 100 Hz and 5000 Hz designed, and in the propagation directions space-longitudinal and transverse to the sound are present.
Durch das einfache Verschieben bzw. Umhängen der Schallschutzvorrichtung kann der arbeitende Mensch selbst über einen nunmehr zufriedenstellenden Sicht- und/oder Schallschutz zu seinem unmittelbaren Nachbarn bestimmen.By simply moving or transferring the soundproofing device, the working person can determine himself via his now satisfactory visual and / or sound insulation to his immediate neighbors.
Folgende Prinzipien werden dabei zur Anwendung gebracht:The following principles are used:
Poröser AbsorberPorous absorber
Bei der Schallabsorption durch poröse Stoffe wird Schallenergie durch Reibung in Wärmeenergie umgewandelt. Das poröse Material muss für optimale Absorptionseigenschaften im interessierenden Frequenzbereich bestimmte Eigenschaften erfüllen. Diese werden hauptsächlich durch die Porosität, den Strukturfaktor und spezifischen sowie längenbezogenen Strömungswiderstand beschrieben. Ein Beispiel dafür ist Mineralwolle mit einem Raumgewicht von 40 kg/m3 und einem längenbezogenen Strömungswiderstand von 11 kPas/m2.In sound absorption by porous substances, sound energy is converted by friction into heat energy. The porous material must fulfill certain properties for optimum absorption properties in the frequency range of interest. These are mainly described by the porosity, the structure factor and specific and length-related flow resistance. An example of this is mineral wool with a density of 40 kg / m 3 and a length-related flow resistance of 11 kPas / m 2 .
Ein wichtiges Kriterium beim Einsatz poröser Absorber stellt das sogenannte Lambda-Viertel-Prinzip dar, nach welchem einer Schallwelle im Bereich ihrer größten Schallschnelle, die meiste Energie entzogen werden kann.An important criterion in the use of porous absorbers is the so-called lambda quarter principle, according to which a sound wave in the region of its largest sound velocity, the most energy can be withdrawn.
Plattenschwinger und LochplattenschwingerPlate vibrator and perforated plate vibrator
Plattenschwinger und Lochplattenschwinger gehören zu den Resonanzabsorbern die nach dem sogenannten Masse-Feder-Prinzip wirken. Dabei wirkt eine Platte als Masse und ein dahinter liegendes Luftvolumen oder Dämpfungsmaterial als Feder. Das Schallfeld regt vor allem tieffrequent die Platte zum Schwingen an, welche ihrerseits diese Energie in Zusammenspiel mit der jeweiligen dahinterliegenden Feder in Wärmeenergie umwandelt. Die Resonanzfrequenz dieses Systems kann wie folgt berechnet werden: wobei, f0 = Resonanzfrequenz, m' = flächenbezogene Masse in kg/m2, dL = Abstand zwischen Plattenrückseite und Wand in cmPlate vibrators and perforated plate vibrators belong to the resonance absorbers which act according to the so-called mass-spring principle. Here, a plate acts as a mass and an underlying air volume or damping material as a spring. Above all, the sound field stimulates the plate to vibrate in a low-frequency manner, which in turn converts this energy into heat energy in interaction with the respective underlying spring. The resonance frequency of this system can be calculated as follows: where, f 0 = resonance frequency, m '= basis weight in kg / m 2 , d L = distance between the back of the panel and the wall in cm
Durch die Auswahl der Feder als Dämpfermaterial oder Luftvolumen bzw. Möbelvolumen, kann die Resonanzfrequenz anwendungsbezogen verschoben und der Frequenzbereich verbreitert werden. Folgendes Beispiel soll diesen Effekt verdeutlichen: Eine 1 m × 1 m große, 50 mm starke Holzplatte, weist aufgrund seiner Masse eine Resonanzfrequenz auf. Diese kann grob durch ein Klopfen auf die Platte herausgefunden werden. Das bedeutet, dass die Platte in diesem Frequenzbereich Schallenergie aufnehmen und umwandeln kann. Diese Absorptionseigenschaft kann durch eine elastische Lagerung der Platte verbessert werden. Als elastisches Medium könnte dabei z. B. ein abgeschlossenes Luftvolumen oder ein elastisches Material zum Einsatz kommen. Das Resultat dieser Maßnahme ist eine erhöhte Absorption in einem breiteren Frequenzband.By selecting the spring as damper material or air volume or furniture volume, the resonance frequency can be moved application-related and the frequency range widened. The following example is intended to illustrate this effect: A 1 m × 1 m large, 50 mm thick wooden plate has a resonant frequency due to its mass. This can be roughly found by tapping on the plate. This means that the disk can absorb and convert sound energy in this frequency range. This absorption property can be improved by an elastic storage of the plate. As an elastic medium could be z. B. a closed air volume or an elastic material can be used. The result of this measure is an increased absorption in a wider frequency band.
Strömungsabsorberflow absorber
Der Strömungsabsorber basiert auf dem Prinzip der Schallabsorption durch hohe Reibungsverluste bei Durchdringung des Schalls durch das Absorptionsmedium. Dabei kommt ein engfaseriges, jedoch noch luftdurchlässiges Material, z. B. ein Akustikvlies, zum Einsatz, welches eine Dicke von 1 mm oft nicht überschreitet.The flow absorber is based on the principle of sound absorption by high friction losses when penetration of the sound through the absorption medium. It comes a tight-fiber, but still air-permeable material, eg. As an acoustic fleece used, which often does not exceed a thickness of 1 mm.
Der optimale Strömungswiderstand liegt generell im Bereich: The optimum flow resistance is generally in the range:
MultiimpedanzabsorberMulti impedance absorber
Aufbau eines porösen Absorbers mit wechselnden StömungswiderständenConstruction of a porous absorber with changing flow resistances
Diese Absorptionsprinzipien addieren sich in einer dünnen Membranschicht, zu einem breitbandigen Hochleistungsabsorber. Er ist mit einem bisher nicht erreichten Absorptionsgrad bei Möbeln von fast 100% und maximaler Wirkbandbreite über den Frequenzbereich von 80 Hz bis 4000 Hz ausgestattet, welcher dadurch generiert wird, dass nicht wie bislang nur ein oder zwei der typischen Absorptionsprinzipien (Strömungsabsorber, z. B. Vlies, oder poröser Absorber, z. B. Dämmstoff) die wesentliche Schallabsorption des Elementes erbringen, sondern die gezielte Auswahl des Wirkprinzips und die Auswahl des dazugehörigen Absorptionsmaterials und die optimale Reihenfolge der ausgewählten mehr als zwei Schallabsorberelemente der Schallschutzvorrichtung.These absorption principles add up in a thin membrane layer, to a broadband high-performance absorber. It is equipped with a previously unattained absorption rate for furniture of almost 100% and maximum effective bandwidth over the frequency range from 80 Hz to 4000 Hz, which is generated by the fact that not one or two of the typical absorption principles (flow absorbers, eg Non-woven, or porous absorber, eg insulating material) provide the substantial sound absorption of the element, but the targeted selection of the active principle and the selection of the associated absorption material and the optimal order of the selected more than two sound absorber elements of the soundproofing device.
