Description
Frequenzvariables Schallschutzelement mit schalldämmender und schallabsorbierender Wirkung.Frequency-variable soundproofing element with sound-insulating and sound-absorbing effects.
Herkömmliche Schallschutzelemente lassen sich in zwei Gruppen differenzieren:Conventional soundproofing elements can be divided into two groups:
I StandardelementeI Standard elements
Standardelemente sind aufgrund ihres Konstruktionsaufbaues und ihrer Bautiefe im allgemeinen lediglich für die Dämmung und Absorption mittel- bis hochfrequenten Schalls wirksam. Darüber hinaus sind sie i.d.R. mit den stark in die Diskussion gekommenen Mineralfaserstoffen als Absorptionsmaterial gefüllt und müssen somit sehr aufwendig verarbeitet und abgedichtet werden, um ein Ausrieseln des Füllmaterials weitestgehend zu verhindern.Due to their construction and depth, standard elements are generally only effective for insulating and absorbing medium to high frequency sound. In addition, they are usually filled with the much discussed mineral fiber materials as absorption material and therefore have to be processed and sealed with great effort in order to prevent the filling material from leaking out as far as possible.
II SonderanfertigungenII Custom-made products
Sonderanfertigungen von Schallschutzelementen kommen überall dort zum Einsatz, wo eine Minderung von Störgeräuschen mit einem stark tieffrequenten Anteil (f *i 200 Hz) gefordert wird.Custom-made soundproofing elements are used wherever a reduction in noise with a strong low-frequency component (f *i 200 Hz) is required.
Da es sich dabei jeweils um Einzelanfertigungen handelt, darüber hinaus für eine hochwertige Schalldämmung kostenintensiveres Material eingesetzt wird, liegt der Preis dieser Schallschutzelemente weit über dem der Standardelemente .Since these are custom-made products, and more expensive materials are used for high-quality sound insulation, the price of these soundproofing elements is far higher than that of standard elements.
Als Absorbermaterial kommen auch hier i.d.R. Mineralfaserstoffe mit den unter I beschriebenen Nachteilen zum Einsatz.Mineral fibres are also generally used as absorber materials here, with the disadvantages described under I.
Aufgabe und Ziel war es, ein Schallschutzelement zu konzipieren, das, bezogen auf die Dämm- und Absorberwirkung, extrem breitbandig sowohl für den tiefen als auch für den mittel- bis hochfrequenten Störschall wirksam ist, jedoch aufgrund des konstruktiven Aufbaues als kostenoptimiertes Standardelement vorgefertigt werden kann.The task and aim was to design a soundproofing element that, in terms of its insulating and absorbing effect, is extremely broadband effective for both low and medium to high frequency noise, but can be prefabricated as a cost-optimized standard element due to its structural design.
Diese Aufgabe wird mit dem im Schutzanspruch 1 aufgeführten frequenzvariablen Schallschutzelement gelöst.This object is achieved with the frequency-variable soundproofing element specified in claim 1.
Durch die deutliche konstruktive Trennung von Absorbereinheit (bestehend aus Absorbermaterial und mechanischer Abdeckung) und Dämmschale ist es möglich, durch Änderung des Abstandes &khgr; (s. Abb. 1 und 2) die akustische Wirksamkeit frequenzabhängig zu variieren. Dieser Konstruktionsaufbau, der darüber hinaus den Vorteil eines sehr geringen Fertigungsaufwandes gegenüber herkömmlichen Schallschutzelementen besitzt, ist besonders für den Einsatz von ausrieselfesten und formstabilen Schaumabsorbern konzipiert, da diese keine allseitige Umschließung benötigen.Due to the clear structural separation of the absorber unit (consisting of absorber material and mechanical cover) and the insulation shell, it is possible to vary the acoustic effectiveness depending on the frequency by changing the distance x (see Fig. 1 and 2). This construction, which also has the advantage of being very easy to manufacture compared to conventional soundproofing elements, is particularly designed for the use of non-spillable and dimensionally stable foam absorbers, as these do not require all-round enclosure.

Außerdem kommen somit die angestrebten Ersatzstoffe zur Mineralfaser zum Einsatz, was in Anbetracht des Einsatzzweckes derartiger Bauelemente, nämlich vorwiegend zum Personenschutz in Industriebetrieben, als weiteres Detail erwähnenswert ist.In addition, the intended substitutes for mineral fiber are used, which is a further detail worth mentioning in view of the intended use of such components, namely primarily for personal protection in industrial plants.
Der mechanische Absorberschutz (Lochblech) umfaßt U-förmig den Absorberkern, sodaß sich eine Schnittkanten- und abdeckungsfreie Elementenoberfläche ergibt.The mechanical absorber protection (perforated sheet) surrounds the absorber core in a U-shape, resulting in an element surface free of cut edges and covers.
Ein weiterer Vorteil dieses Konstruktionsprinzips ist im Schutzanspruch 2 wiedergegeben.A further advantage of this design principle is set out in claim 2.
Dabei wird die Absorbereinheit mittels eines Distanzstückes vor der bauseitig vorhandenen Schalldämmung (z.B. Betonwand) montiert, wobei auch hier der Abstand &khgr; frequenzabhängig festgelegt wird.The absorber unit is mounted using a spacer in front of the existing sound insulation (e.g. concrete wall), whereby the distance x is also determined depending on the frequency.
Vor allem ist das konstruktionsbedingte geringe Gewicht der der Absorbereinheit interessant, das nur zu einer minimalen statischen Beaufschlagung des bestehenden Gebäudeteils führt.What is particularly interesting is the low weight of the absorber unit due to its design, which only results in minimal static loading of the existing part of the building.
Ein Konstruktionsaufbau wie vorbeschrieben wird in den Abb. 1 bis 3 dargestellt:A construction structure as described above is shown in Figures 1 to 3:
