Description
Die Erfindung geht aus von einer Vorrichtung zur Schalldämpfung. The invention relates to a device for soundproofing.
Derartige Vorrichtungen werden in geschlossenen Räumen, die für verschiedene Arten von Aufführungen und Veranstaltungen genutzt werden, eingesetzt um die Ausbreitung von Schall zu beeinflussen. Bei derartigen Räumen handelt es sich beispielsweise um Konzertsäle, Multifunktionshallen oder Vortragssäle. Findet in dem Raum beispielsweise eine Aufführung eines klassischen Konzerts, eines Liederabends oder eine Oper ohne Audioverstärker statt, so ist eine gewisse Schallreflexion an den Wänden und der Decke des Raums erwünscht. Bei Vorträgen und Konzerten, bei denen Audioverstärker eingesetzt werden, ist dagegen eine Schallreflexion an Wänden und Decke des Raums zur besseren Akustik zu vermeiden. Um diese Anforderungen erfüllen zu können, sind Räume für Aufführungen ohne Audioverstärker an Wänden und/ oder anders ausgestattet als Räume für Aufführungen mit Audioverstärker. Letztere weisen an Wand und/ oder Decke häufig Elemente auf, welche den Schall nicht reflektieren oder sogar absorbieren. Such devices are used in closed spaces that are used for various types of performances and events to influence the propagation of sound. Such rooms are, for example, concert halls, multifunctional halls or lecture theaters. If, for example, a performance of a classical concert, a recital or an opera without an audio amplifier takes place in the room, a certain amount of sound reflection on the walls and ceiling of the room is desired. At lectures and concerts where audio amplifiers are used, however, a sound reflection on the walls and ceiling of the room should be avoided for better acoustics. In order to meet these requirements, rooms for performances without audio amplifiers are on walls and / or differently equipped than rooms for performances with audio amplifiers. The latter often have elements on the wall and / or ceiling which do not reflect or even absorb the sound.
Als nachteilig erweist sich, dass aufgrund der unterschiedlichen Anforderungen an die Raumakustik eine vielseitige Nutzung des Raums ausgeschlossen ist. A disadvantage proves that due to the different requirements for room acoustics a versatile use of the room is excluded.
Es sind Markisen oder sonstige Vorrichtungen zum Schutz gegen einfallende Sonne bekannt, die jedoch nicht geeignet sind, die Raumakustik in einem geschlossenen Raum derart zu beeinflussen, dass eine vielseitige Nutzung des Raumes möglich ist. There are awnings or other devices for protection against incident sun known, but which are not suitable to influence the room acoustics in a closed space such that a versatile use of the room is possible.
So offenbart die
Die
Gegenstand der
Der Erfindung liegt die Aufgabe zugrunde eine Vorrichtung zur Schalldämpfung zur Verfügung zu stellen, die bei Bedarf eine Ausstattung der Wände und/ oder Decke eines Raums mit einem schallschluckenden Element ermöglicht, und die ferner das Entfernen des schallschluckenden Elements bei Nichtgebrauch ermöglicht. The invention has for its object to provide a device for soundproofing available that allows if necessary, an equipment of the walls and / or ceiling of a room with a sound-absorbing element, and also allows the removal of the sound-absorbing element when not in use.
Die Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Die Vorrichtung zeichnet sich dadurch aus, dass zwei schallschluckende Strukturen mit mindestens zwei Lagen vorgehen sind, die bei Nichtgebrauch auf zwei parallel angeordnete Wellen aufgerollt sind und bei Bedarf durch eine Aufspanneinrichtung von den Wellen abgerollt und aufgespannt werden. Die Vorrichtung weist einen Motor auf, der die Aufspanneinrichtung bei Bedarf in die jeweils gewünschte Richtung bewegt. Die Anzahl der verwendeten Vorrichtungen hängt von der Größe des Raums ab. The object is achieved by a device having the features of
Bei der schallschluckenden Struktur handelt es sich um ein flexibles flächiges Gebilde mit mindestens zwei Lagen. Die erste Lage besteht aus einem perforierten Element mit einer Vielzahl von Durchgangslöchern. Die zweite Lage ist an der ersten Lage befestigt und besteht aus einem Fasermaterial, beispielsweise einem Vlies oder einem Vliesstoff. Dabei wird die Vorrichtung derart in dem Raum vor einer Wand und/ oder Decke angeordnet, dass die schallschluckende Struktur in der ausgefahrenen und aufgespannten Stellung mit dem perforierten Element der Schallquelle zugewandt ist. The sound-absorbing structure is a flexible, flat structure with at least two layers. The first layer consists of a perforated element with a plurality of through holes. The second layer is attached to the first layer and consists of a fiber material, for example a nonwoven or a nonwoven fabric. In this case, the device is arranged in the space in front of a wall and / or ceiling, that the sound-absorbing structure in the extended and clamped position facing the perforated element of the sound source.
In bevorzugter Weise wird die Vorrichtung vor einer Wand angeordnet und mit ihrem Gehäuse im Boden versenkt, so dass sie bei eingefahrener Aufspanneinrichtung nicht sichtbar ist. Hierzu kann das Gehäuse mit einem Deckelement abgedeckt sein, das an der Aufspanneinrichtung angeordnet ist. Beim Ausfahren richtet sich die Aufspanneinrichtung senkrecht nach oben auf und spannt die schallschluckende Struktur in der Vertikalen auf. Preferably, the device is placed in front of a wall and sunk with its housing in the ground, so that it is not visible when retracted jig. For this purpose, the housing may be covered with a cover element which is arranged on the clamping device. During extension, the jig is directed vertically upwards and clamps the sound-absorbing structure in the vertical direction.
Vorteile und vorteilhafte Ausgestaltung der Erfindung sind der nachfolgenden Beschreibung, der Zeichnung und den Ansprüchen zu entnehmen. Advantages and advantageous embodiment of the invention are apparent from the following description, the drawings and the claims.

In der eingefahrenen Position der Aufspanneinrichtung sind die beiden schallschluckenden Elemente
Die beiden schallschluckenden Strukturen sind mit ihrem in der Zeichnung nicht erkennbaren perforierten Element in dieselbe Richtung ausgerichtet. Durch die beiden Strukturen wird das Schall besser absorbiert als nur mit einer schallschluckenden Struktur. The two sound-absorbing structures are aligned in the same direction with their perforated element, not visible in the drawing. The two structures absorb the sound better than just a sound-absorbing structure.
Sämtliche Merkmale können sowohl einzeln als auch in beliebiger Kombination miteinander erfindungswesentlich sein. All features may be essential to the invention both individually and in any combination.
