In a sound-absorbing device (1) which is suspended from ceilings (3) in rooms (2), comprising a frame (4) which is fastened at a distance from the ceiling (3) and parallel thereto, and at least one flat structure with sound-absorbing properties which is inlaid or inserted into the frame (4),
on the one hand a sound-absorbing property should be present as far as possible over the entire surface of the ceiling (3) and on the other hand sufficient illumination should be possible for the interior of the room. This is solved in accordance with the present invention by at least one intermediate space (11) being provided in the flat structure (5), by one or more lighting means (12) being arranged in the respective intermediate space (11), and by each of the lighting means (12) being locked to the frame (4) directly or by means of support elements (13).

A thermoplastic frame for holding acoustical material has extruded square plastic tubing that is inserted or snap-fit onto corner connectors and T-connectors to make an enclosure that houses and compresses the acoustic material. During assembly of the frame, the acoustic material is inserted in the open side of a secondary frame assembly and enclosed and compressed with a cap assembly snap-fit onto the secondary frame assembly.

A sound insulation plate includes a patterned frame and an elastic membrane, wherein the patterned frame includes a central pattern region and multiple peripheral pattern regions arranged around the central pattern region, the multiple peripheral pattern regions being separated from the central pattern region by a separation bar, and wherein the elastic membrane is mounted on the patterned frame to block passage of air and converts airborne sound waves into elastic waves.

There is provided a soundproof structure capable of obtaining a sufficient soundproofing effect by suppressing the leaking of sound due to a diffraction phenomenon in a partition member used for soundproofing. A soundproof unit, which has a frame body having an opening portion and a film that is disposed so as to cover the opening portion and vibrates according to a sound incident on the film, and a partition member, to which one or more soundproof units are attached, are provided.

A method for implementing a channel (56) includes providing a preform (20) having a recess (22) therein and heating a channel implementation element (30) to a temperature greater than a melting temperature of a material of the preform (20). An external contour of the channel implementation element (30) at least regionally corresponds to an internal contour of the channel (56) to be implemented. The method then moves the heated channel implementation and/or the preform (20) in relation to one another so that the heated channel implementation element (56) at least regionally moves into the recess (22) in a moving-in direction. The material of the preform (20) is at least partially melted in a region around the recess (20) and is at least partially displaced by the channel implementation element (30), wherein at least a part of the channel (56) to be implemented is thus implemented.

An acoustic tile, methods of forming and installing the same, and a frame for such are provided. The acoustic tile includes a substantially planar board, where the board can include fiberglass. A frame, which can include a plurality of frame segments, is disposed about a portion of a periphery of the substantially planar board. The frame is coupled to the board where an edge of the board is disposed within a channel of the frame. The frame imparts a majority of the dimensional stability of the acoustic tile, where the frame can include one of extruded metal, extruded plastic, and pultruded fiberglass. The acoustic tile includes a mounting point on the frame configured for coupling the frame to the building surface. A wrapping can be included that substantially covers a face of the board. The acoustic tile can function to absorb, block, or diffuse sound energy.

Sound absorbing material for use in rooms inside buildings. The material comprises a continuous polymeric film (11) having smooth surfaces, said film having a thickness (t) of about 0.1 to 0.3 mm. The film is provided with numerous substantially parallel discontinuous microslits (12) with a degree of perforation of from 0.3-3%. The microslits are cut with laser devices to produce a highly smooth and level surface. The film is tensioned in a frame (16) with a level film surface or curved film surface.

An acoustically absorbent assembly intended to constitute, inside premises, a partition element able to be fixed to at least one partition for producing false partitions, comprising: two fabrics parallel to each other and assembled on an attachment means at a periphery of the two fabrics, the fabrics defining respectively an inner fabric and an outer fabric when the assembly is fixed to the partition, one of the fabrics being free from perforations, wherein the outer fabric is disposed at a given distance from the inner fabric and the outer fabric comprises microperforations configured as an acoustic fabric.

A room divider system comprising at least one panel having a first sheet and a second sheet spaced apart by means of at least one lath, wherein said system further comprises a connector forming a rigid structure for associated equipment, said connector being configured to be at least partially inserted in a cavity formed between said first and second sheets, wherein the connector is arranged to be attached to the at least one lath.
