The invention relates to an acoustic panel (1) for producing a wall and ceiling lining, comprising a front face (2) and a rear face (3) and recesses (4, 6) which extend from the front face (2) and from the rear face (3) into the acoustic panel. In order to provide an acoustic panel which both prevents the ability to see through from the front face to the absorber and also prevents particles from passing from the absorber through the acoustic panel (1), according to the invention at least one front-face recess and one rear-face recess (6) are arranged so as to be partially offset from one another and comprise a through-opening (7).

Sound-permeable lining (1) for covering perforations (21) shaped in an acoustic plasterboard (2). The sound-permeable lining (1) comprises a first ply (12) of a fleece material and attached thereto a second ply (14) which is arranged in between of the first ply (12) and the acoustic plasterboard (2) to which the sound-permeable lining (1) is to be applied. The second ply (14) being of a foil material having a second opacity O.sub.2 and a plurality of through-holes (141) formed therein. The first ply (12) has a first opacity O.sub.1 so that the through-holes (141) formed in the second ply (14) are invisible through the first ply (12) and so that the applied sound-permeable lining (1) has an overall opacity O.sub.12 to allow for optically covering the perforations (21) shaped in the acoustic plasterboard (2) and an overall air flow resistivity R.sub.s12 to allow for the penetration of air so that sound can propagate via the sound-permeable lining (1).

A panel for a surface covering system of a plurality of like panels, the panel comprising: a base layer; a first joint extrusion attached along a first edge of the base layer; a second joint extrusion attached along a second edge of the base layer, opposite the first edge; a covering layer covering at least part of the first joint extrusion and at least part of the second joint extrusion; wherein the first extrusion is configured to join to a second extrusion of an adjacent like panel, and the covering layer substantially conceals the first extrusion and the second extrusion when installed.

The present invention is enclosed in the area of acoustic treatment, therefore solutions for adapting/tuning the acoustic performance of a space, wherein such space may take very varied forms: a living space such as a living or sleeping room (100), a lobby or a recording room (100). It is an object of the present invention a sound tuning layer which is PE based and obtained from the steps of sublimation of a PE based starting material with an open cell structure, and subsequent cold pressing, said cold pressing being performed at a lower temperature as regards the sublimation step, and while the sublimated sound tuning layer is still hot, and thereby forming the sound tuning layer, with an open cell structure. It therefore provides a more environmentally friendly and simple solution than those of prior art. It is also an object of the present invention a panel for acoustic treatment of a space, which comprises such layer.

A sound damping wallboard for installation on an installed wallboard, a sound damping wallboard system, and a method of constructing a sound damping wallboard on a building structure are disclosed. The sound damping wallboard comprises a gypsum layer having a gypsum layer inner surface and a gypsum layer outer surface, a sound damping layer disposed at the gypsum layer inner surface for installation between the gypsum layer and an installed wallboard and having a sound damping layer inner surface, a first encasing layer disposed at the gypsum layer outer surface, and a second encasing layer disposed at the sound damping layer inner surface.

A locking dynamic high NRC acoustic baffle and/or tile and a locking dynamic high NRC ceiling and/or wall system, that includes a single piece of material folded into locking dynamic high NRC acoustic baffles and/or tiles, using locking pieces and locking mechanisms, to quickly and easily install the locking dynamic high NRC acoustic baffle and/or tile onto construction ceiling hangers or onto walls to provide an aesthetically pleasing image, along with a reduction in unwanted noise or room acoustics.

A perforated acoustic panel for mounting to a wall and/or a ceiling, including a visible front side and a rear side hidden by the panel when mounted is discussed. It is an objective of the disclosure to provide illuminating walls or ceilings. The objective is solved by a flexible printed circuit layer, FPC, attached to the rear side of the panel, the FPC comprising a plurality of LEDs, wherein each LED is arranged to be positioned to emit light through a perforation of the panel.

An acoustic tile made from a single piece of material folded along a plurality of folding scores to form a three-dimensional configuration. The three-dimensional configuration includes a plurality of folded extensions, a plurality of outer surfaces arranged to collectively form a faceted dome, a plurality of inner surfaces comprising a plurality of recesses. The acoustic tile also includes a plurality of locking pieces which engage the plurality of recesses to hold the single piece of material in the three-dimensional configuration.
