Embodiment Construction

[0033] figure 1 The lower face of the ceiling of a soundproof room 01 according to the invention is shown not drawn to scale, which represents the upper edge region of the room 01 . The building area of ​​the room is preferably 40m 2 up to 130m 2 . The room is equipped with a sound absorber installation according to the invention.

[0034] For this purpose, a sound-absorbing absorber strip 03 extending along the abutment edge 02 is arranged circumferentially on the upper abutment edge 02 of the room 01 . The absorbing strip 03 can be located on the ceiling or the wall of the room 01 and can extend into a corner (butt edge) formed between the wall and the ceiling in each case. Between the ceiling and the absorbing strip 03 or between the wall and the absorbing strip 03 there is a solid, possibly full-surface connection, for example in the form of an adhesive connection or a mechanical connection, for example by means of clips. The wall or the ceiling can have recesses for ...

Abstract

The present invention relates to a sound absorber arrangement comprising a plurality of sound absorber elements which are arranged in a room (01) having walls and a ceiling which closes off the room to the top. A plurality of juxtaposed sound absorber elements form one or more absorber strips (03) which extend at least in certain portions along an upper abutting edge which extends between the walland ceiling of the room (01). The sound absorber elements have a width of 200-400 mm and a thickness of 40-65 mm. The sound absorber elements have a length-specific flow resistance in the range of 5-20 kPa*s/m<4>. The invention further relates to a sound-damped room (01) having such a sound absorber arrangement.

Description

technical field [0001] The invention relates to sound-absorbing installations and sound-insulated rooms using sound-absorbing elements and sound-absorbing absorbing strips composed of these elements. Background technique [0002] Elements for improving room acoustics, ie for improving speech intelligibility and sound absorption for hearing protection, have long been known. Acoustic ceilings made of plasterboard or fiberboard improve room acoustics, reduce reverberation and convert sound energy into heat. Special solutions exist for studios or studios, such as corner cabinets with elongated slits and backings of fleece or foam as bass absorbers. In addition, acoustic wall finishes are also known, such as panels that are mounted on walls at various angles and sizes and act as low frequency absorbers that absorb low audio frequencies. High audio frequencies are usually absorbed using perforated panels mounted at a distance to the wall. Between these perforated panels and the...
