Abstract

The panel (1) possesses, in parallel, opposite surfaces, a plurality of grooves (3a, 3b) which open in the shape of a funnel. At their intersections, the grooves (3a, 3b) form comparatively small holes (5). The grooves (3a, 3b) have a funnel-shaped cross-section, so that sound emerging behind the panel (1) is scattered and effectively conveyed to a backing layer made, for example, of glass fibres. The panel (1) is flexible and reflects incident light well. <IMAGE>

Description

Die Erfindung betrifft eine schallabsorbierende Platte nach dem Oberbegriff des unabhängigen Patentanspruchs 1. Im Stand der Technik sind schallabsorbierende Lochplatten als Wand­verkleidungen gut bekannt. Diese arbeitet nach dem Prinzip der Helmholtz-Resonatoren. Der schallabsorbierende Effekt der Lochplatten beruht darauf, das ein wesentlicher Anteil der auftreffenden Schallenergie absorbiert, aber nicht mehr reflektiert wird. Die Platten lassen den Schall durch Löcher in das Innere der Wand eindringen, aber lassen einen Anteil des eingedrungenen Schalls nicht wieder heraus.The invention relates to a sound absorbing panel according to the preamble of independent claim 1. Sound absorbing perforated panels are well known as wall cladding in the prior art. This works on the principle of the Helmholtz resonators. The sound-absorbing effect of the perforated panels is based on the fact that a significant proportion of the incident sound energy is absorbed, but is no longer reflected. The panels allow the sound to penetrate the interior of the wall through holes, but do not let some of the sound penetrate out.

Bekannt ist auch eine Lochplatte aus einer furnierten Spann­platte. Die Spannplatte weist Sacklöcher mit vergleichsweise grossem Radius auf, während das Furnier vergleichsweise kleine Löcher aufweist, die den auftreffenden Schall in die Sack­löcher leiten. Bei dieser furnierten Spannplatte besteht die Schwierigkeit, dass sie einerseits in der Herstellung teuer und aufwendig ist, und dass anderseits die Löcher leicht verschmutzen und kaum zu reinigen sind. Da diese Platte wenig biegbar ist, ist ihre Anwendung entsprechend beschränkt.A perforated plate made of a veneered clamping plate is also known. The clamping plate has blind holes with a comparatively large radius, while the veneer has comparatively small holes that guide the impinging sound into the blind holes. The problem with this veneered clamping plate is that it is expensive and complex to manufacture on the one hand and that the holes are easy on the other soiled and can hardly be cleaned. Since this plate is not very flexible, its use is limited accordingly.

Der Erfindung liegt die Aufgabe zugrunde, eine schallabsorbierende Platte der im Oberbegriff des Patentanspruchs 1 genannten Gattung zu schaffen, die nicht nur hervorragend schallab­sorbierend ist, sondern auch in der Raumgestaltung zahlreiche Variationen ermöglichen.The invention has for its object to provide a sound absorbing plate of the type mentioned in the preamble of claim 1, which is not only excellent sound absorbing, but also allow numerous variations in the room design.

Die Aufgabe wird durch die Erfindung gemäss Patentanspruch 1 gelöst.The object is achieved by the invention according to claim 1.

Die erfindungsgemässe Platte gemäss Anspruch 2 zeigt eben­falls den Helmholtz-Effekt, vermeidet jedoch teure Bohrungen. Messungen im Kundt'schen Rohr haben einen durchschnittlichen Absorptionsgrad α von 0,55 ergeben. Im Bereich von 500 bis 2000 Hz stieg der Absorptionsgrad von 0,6 auf 0,9. Die erfindungs­gemässe Platte weist somit insbesondere im Bereich der meist besonders störenden hohen Frequenzen hervorragende akustische Eigenschaften auf. Die Fräsungen ermöglichen ein Formen und Biegen der Platte, ohne dass hierbei die Löcher geschlossen werden. Es können somit auch gebogene Wandflächen durch ge­formte oder gebogene Platten verkleidet werden. Die vergleichs­weise kleinen Löcher sind kaum sichtbar, was oft gewünscht ist.The plate according to the invention also has the Helmholtz effect, but avoids expensive drilling. Measurements in Kundt's tube have an average degree of absorption α of 0.55. In the range from 500 to 2000 Hz, the degree of absorption rose from 0.6 to 0.9. The plate according to the invention thus has excellent acoustic properties, particularly in the region of the mostly particularly disruptive high frequencies. The millings allow the plate to be shaped and bent without closing the holes. Curved wall surfaces can thus also be clad with shaped or curved panels. The comparatively small holes are hardly visible, which is often desired.

Durch unterschiedliche Nutentiefen können in einfacher Weise an der gleichen Platte unterschiedliche Lochgrössen erreicht werden. Die offene Fläche beträgt vorzugsweise etwa 2% und der Durchmesser der Löcher beträgt beispielsweise etwa 1 mm. Eine solche Platte reflektiert auftreffendes Licht gut und eignet sich auch als Lichtreflektkor bespielsweise über einem Arbeits­platz mit lärmerzeugenden Maschinen, beispielsweise in einem Computerraum.Different groove sizes can be easily achieved on the same plate by different groove depths. The open area is preferably about 2% and the diameter of the holes is, for example, about 1 mm. Such a plate reflects incident light well and is also suitable as a light reflector, for example, over a workplace with noise-generating machines, for example in a computer room.

Nach einer Weiterbildung der Erfindung sind die Nuten im Quer­schnitt trichterförmig. Diese Platte ist weitgehend selbst­reinigend. Besonders einfach sind solche Nuten dann herstell­bar, wenn sie im Querschnitt V-förmig sind.According to a development of the invention, the grooves are funnel-shaped in cross section. This plate is largely self-cleaning. Such grooves are particularly easy to produce if they are V-shaped in cross section.

Gemäss einer bevorzugten Ausführung sind die Nuten im Bereich des Nutengrundes V-förmig und weisen diese Nuten etwa parallele Flanken auf. Die Abstände zwischen den Nuten können verglichen mit V-förmigen Nuten kleiner gewählt und damit pro Fläche mehr Löcher geschaffen werden.According to a preferred embodiment, the grooves are V-shaped in the area of the groove base and these grooves have approximately parallel flanks. The distances between the grooves can be chosen to be smaller compared to V-shaped grooves and thus more holes can be created per surface.

Weitere vorteilhafte Merkmale ergeben sich aus der nachfolgenden Beschreibung und der Zeichnungen. Zwei Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1a und 1b Teilansichten der Schmalseite einer Platte ge­mäss einer ersten bzw. zweiten Variante der Erfindung,
  • Fig. 2 eine Ansicht der Platte nach Fig. 1a in Richtung des Pfeiles II gesehen,
  • Fig. 3 eine Ansicht der Platte gemäss Fig. 1a in Richtung des Pfeiles III gesehen,
  • Fig. 4 einen Teilschnitt durch die Platte gemäss Fig. 1b, und
  • Fig. 5 schematisch eine teilweise gebogene Platte.
Further advantageous features result from the following description and the drawings. Two exemplary embodiments of the invention are explained in more detail below with reference to the drawing. Show it:
  • 1a and 1b partial views of the narrow side of a plate according to a first and second variant of the invention,
  • 2 is a view of the plate of FIG. 1a seen in the direction of arrow II,
  • 3 is a view of the plate according to FIG. 1a seen in the direction of arrow III,
  • Fig. 4 is a partial section through the plate according to Fig. 1b, and
  • Fig. 5 schematically shows a partially curved plate.

Die in Fig. 1a gezeigte Platte ist eine Sperrholzplatte mit einer Dicke von etwa 7 mm. Die Platte kann jedoch auch aus einem geeignetem Kunststoff bestehen. Selbstverständlich sind auch geringere oder höhere Stärken möglich. Wie die Fig. 1a in Verbindung mit den Fig. 2 und 3 zeigt, sind in Oberflächen 20a und 20b mehrere parallele und gerade Nuten 3a bzw. 3b eingearbeitet. Die Nutentiefe beträgt etwa 4 mm, so dass an den Schnittstellen der Nuten unterschiedlicher Oberflächen durch quadratische Durchbrüche 5 vorhanden sind. Wie die Fig. 1a zeigt, weisen die Nuten parallele Flankenflächen 22 und sich schneidende Flächen 21 auf. Die Flächen 21 bilden den Nutengrund und schneiden sich etwa unter einem Winkel von 90°.The plate shown in Fig. 1a is a plywood plate with a thickness of about 7 mm. However, the plate can also consist of a suitable plastic. Of course, lower or higher strengths are also possible. As shown in FIG. 1a in connection with FIGS. 2 and 3, several parallel and straight grooves 3a and 3b are incorporated in surfaces 20a and 20b. The groove depth is approximately 4 mm, so that there are different openings through square openings 5 at the intersections of the grooves. As FIG. 1 a shows, the grooves have parallel flank surfaces 22 and intersecting surfaces 21. The surfaces 21 form the bottom of the groove and intersect approximately at an angle of 90 °.

Die Fig. 1b zeigt eine weitere Platte 2, bei welcher die Nuten 4a bzw. 4b im Querschnitt V-förmig sind. Die Flankenflächen 11 schneiden sich unter einem Winkel der wesentlich kleiner als 90° ist. Ausser den hier gezeigten Nuten sind auch andere Nutenformen, beispielsweise im Querschnitt U-förmige Nuten denkbar. Die Nuten können auch gebogen, oder zick-zack-förmig sein.1b shows a further plate 2, in which the grooves 4a and 4b are V-shaped in cross section. The flank surfaces 11 intersect at an angle that is significantly smaller than 90 °. In addition to the grooves shown here, there are others Groove shapes, for example, U-shaped grooves in cross section are conceivable. The grooves can also be curved or zigzag-shaped.

Die Fig. 2 zeigt eine Platte 2, die beispielsweise als Decke­verkleidung an einer Decke 12 befestigt ist. Der in Richtung des Pfeiles 7 auf die Platte auftreffende Schall tritt durch die Löcher 6 in die Nuten 4a ein. Der durch die Linien 8 hier schematisch dargestellte Schall wird durch das die Nuten 4a umgebende Material absorbiert. Selbstverständlich können zwischen der Platte 2 und der Decke 12 noch weitere erfindungs­gemässe Platten oder andere schallabsorbierende Platten ange­ordnet werden. Die Platte 1 bzw. 2 wird vorzugsweise mit Glas­wolle, Steinwolle oder dergleichen hinterlegt. Der hinter der Platte 1 bzw. 2 austretende Schall wird durch die trichter­förmigen Nuten gestreut und kann dadurch besonders wirksam in die hinter der Platte angeordnete schallabsorbierende Schicht eindringen.FIG. 2 shows a plate 2 which is fastened to a ceiling 12, for example as a ceiling covering. The sound impinging on the plate in the direction of arrow 7 enters the grooves 4a through the holes 6. The sound schematically represented here by the lines 8 is absorbed by the material surrounding the grooves 4a. Of course, further panels according to the invention or other sound-absorbing panels can be arranged between the panel 2 and the ceiling 12. The plate 1 or 2 is preferably backed with glass wool, rock wool or the like. The sound emerging behind the plate 1 or 2 is scattered by the funnel-shaped grooves and can thus penetrate particularly effectively into the sound-absorbing layer arranged behind the plate.

Es hat sich gezeigt, dass an der erfindungsgemässen Platte tiefe Töne durch Resonanz aufgenommen werden.It has been shown that low tones are recorded by resonance on the plate according to the invention.

Wie in Fig. 5 rein schematisch dargestellt ist, kann die Platte 2 teilweise oder ganz gebogen sein. Die erfindungsgemässen Platten 1 bzw. 2 sind dank der sich kreuzenden Nuten ähnlich einer Platte aus Gummi sehr flexibel. Ein wesentlicher Aspekt der Erfindung besteht auch darin, dass die erfindungsgemässen Platten 1 bzw. 2 auf beiden Seiten gleich ausgebildet sein können, was die Herstellung und die Anwendung wesentlich er­leichtert. Die Nuten der vorderen Oberfläche können auch eine geringere Tiefe aufweisen als die Nuten der hinteren Ober­fläche, oder können sogar durch Bohrungen ersetzt sein.As shown purely schematically in Fig. 5, the plate 2 can be partially or completely curved. The plates 1 and 2 according to the invention are very flexible thanks to the intersecting grooves, similar to a plate made of rubber. An essential aspect of the invention is that the inventive Plates 1 and 2 can be of identical design on both sides, which considerably simplifies production and use. The grooves of the front surface can also have a smaller depth than the grooves of the rear surface, or can even be replaced by bores.

Trotz der erheblichen Vorteile der erfindungsgemässen Platte ist diese ersichtlich sehr einfach und mit geringem Material­aufwand realisierbar, so dass erfindungsgemäss eine schall­absorbierende und zugleich gut lichtreflektierende Platte ge­schaffen wurde, welche nicht nur den akustischen Anforderungen in hervorragender Weise Rechnung trägt, sondern aufgrund ihrer Flexibilität in der Raumgestaltung vielfältig verwendbar ist.Despite the considerable advantages of the panel according to the invention, it is evidently very simple and can be implemented with little material, so that according to the invention a sound-absorbing and at the same time light-reflecting panel was created, which not only takes account of the acoustic requirements in an excellent manner, but also because of its flexibility in the interior design is versatile.
