Definitions
- the invention relates to a sound-absorbing glass or transparent synthetic glass component according to the preamble of claim 1, as is known from DE-G 91 1 6 233.6 U1 b.
- Conventional sound absorbers use porous or fibrous material to convert airborne sound vibrations into heat through friction on their finely structured, as open as possible surface structure (passive absorber).
- the object of the invention is to provide a glass component which is sound-absorbing and remains transparent. This object is achieved by claim 1, advantageous embodiments are characterized in the subclaims.
- the new absorber itself consists exclusively of one or more completely light-transparent plates, which in themselves are hardly excitable by airborne sound waves. It is made up of a large number of very small continuous holes in its surface facing the room in connection with a cavity arranged behind it (for example in the manner of the micro-perforated plates described in [5] before a sound-hard boundary) for the absorption of incident sound waves in one wide frequency band in the listening area.
- the holes can be made by means of drills, lasers, plasma welding systems.
- sound absorbers which can be retrofitted and which do not impair the architectural design are provided in a plane-parallel manner, if possible directly in front of the reflecting glass components.
- the principle of the micro-perforated transparent sound absorber can be advantageously implemented in 3 constructional variants.
- the absorber according to Figure 1 in front of the actual glass components, e.g. In their given frame constructions, which are subsequently inserted, their building physics, lighting technology and optical functions can be practically completely preserved.
- the holes e.g. with diameters d between 0.2 and 2 mm and spacing b of the holes from between 2 and 10 mm
- the holes can be made so small and regularly in the front shells that the transparency suffers only insignificantly.
- the space between the facing shell and the glass component can be closed as indicated in Figure 1.
- the front cover can also be hung without a side closure. The absorption works as long as the distance is small compared to the transverse dimensions of the facing shell.
- the front cover can be flat, oblique or layered and curved, convex or structured, eg corrugated, zigzag-nubbed pyramid-shaped, etc.
- the facing shell can be edged as shown in Figure 1 .3 or arranged to span a corner.
- the absorbers as independent components e.g. integrated in walls, ceilings and false ceilings or even placed in front of existing components, depending on or placed in front, then they not only enable an absorption that can be adjusted to the respective requirements, but also additionally scatter in targeted reflections of sound waves in room areas where they are harmless or are absorbed there.
- the absorber can also take on constructional functions: as a kind of glass building block with high sound insulation, e.g. in suspended ceiling systems, for example according to [6] and partition walls, but also as a sound-absorbing and sound-absorbing component for enclosures, cabins and ducts.
- Versions according to Figures 2 and 3, in which the section through a component according to the invention is shown, are particularly advantageous since they can be arranged to be movable in the room and the acoustics can thus be "varied", e.g. Depending on the number of people, fewer or more absorbent glass components can be set up in a room, thus dampening the noise, ambient noise or the background of the conversation.
- the thickness of the glass components according to the invention can be between 2 and 20 mm, advantageously (because of the weight) between 4 and 8 mm.
- the hole cross section can be round, oval, irregular or polygonal, the hole can be parallel, conical inwards or outwards or obliquely through the plate.
- the plate can additionally be designed to reflect outside or inside for visible or infra-red light or especially for thermal purposes.
- Figure 7 shows another version of a single plate made of plexiglass, whereby the parameters have been changed compared to the other two Figures 5 and 6, namely the thickness with 0.2 mm, hole diameter 0.16 mm. Hole spacing 1, 4 mm, distance to the rear wall 600 mm and the perforated area with 1, 03%.
- the very thin plastic plates with a thickness of 0.2 mm are thicker films which then have stiffeners, so that the plates cannot be excited to vibrate by the impinging sound. These stiffeners can be thickened areas or glued-on strips made of the same material.
