The present invention relates to panels that can be used to cover interior surfaces in buildings, for instance in auditoriums, open-plan offices etc., where the panels can be used in buildings with thermally activated building systems (TABS) in which balancing of acoustics and thermal comfort is a well-recognized challenge. According to a first embodiment of the invention there is provided a panel comprising one or more sound-absorbing elements (3) and sub-regions (7, 8, 9) that connect the front (11) of the panel with the rear (12) of the panel, and in which sub-regions (7, 8, 9) sound-absorbing elements (3) are not present, whereby said sub-regions (7, 8, 9) ensure thermal transmission through the panel. According to a second embodiment of the invention the panels comprise a substantially rigid frame (1) defining a region within the frame, where the region is provided with one or more sound-absorbing elements comprising a front face and a rear face, where the one or more sound-absorbing elements extend(s) over the entire region defined by the frame (1) and where said sub-regions (22) are provided through said sound-absorbing elements, such that the sub-regions (22) connect said front face and rear face of the one or more sound-absorbing elements.

1. A panel comprising: a front and a rear,at least one sound absorbing element,at least one sub-region that extends from the front of the panel to the rear of the panel, the sub region or sub regions being free of sound absorbing elements to provide thermal transmission between the front of the pane
1. A panel comprising: a front and a rear,at least one sound absorbing element,at least one sub-region that extends from the front of the panel to the rear of the panel, the sub region or sub regions being free of sound absorbing elements to provide thermal transmission between the front of the panel and the rear of the panel,the panel comprising brackets which provide a receptacle between them and said sound absorbing element located in said receptacle,at least one bracket including apertures therethough which provide direct access from a sub-region to a side face of the sound absorbing material in the receptacle. 2. A panel according to claim 1, wherein the panel comprises a frame located at its periphery, and the brackets extending across the frame from one side of the panel to an opposite side of the panel. 3. A panel according to claim 1, wherein said sub-regions provide fluid connection between said front and rear of the panel. 4. A panel according to claim 1, wherein said sub-regions are provided with a material with high thermal conductivity which blocks fluid communication between the front and rear of the panel. 5. A panel according to claim 1, wherein the panel comprises a substantially rigid frame defining said receptacle within the frame, which is provided with one or more sound-absorbing elements comprising a front face, a rear face and a plurality of side faces, arranged in said receptacle in such a manner that at least some of said side faces are exposed to a sound field in the surroundings, in which said panel is placed. 6. A panel according to claim 1, wherein said sound-absorbing elements are substantially box-shaped. 7. A panel according to claim 1, wherein the dimensions of said sound-absorbing elements are chosen according to the lowest frequency at which substantial sound absorption shall take place. 8. A panel according to claim 2, wherein said frame is furthermore provided with a sheet of flexible material suspended over the front of the frame. 9. A panel according to claim 1, wherein said apertures are in the form of a mesh or a fabric.
