An aircraft cabin plate absorber includes a supporting panel, a cover panel and an intermediate layer which is arranged between the supporting panel and the cover panel. The cover panel includes a cover layer which is visible from the cabin space, and is arranged on the supporting panel on the side facing the sound inside the cabin space. The cover panel is fastened to the supporting panel by the intermediate layer, and comprises at least one connecting region, in which it is connected to the supporting panel, and at least one absorption region, in which it is arranged so as to oscillate with respect to the supporting panel. The panel is optimized in term of space requirement and weight for use in aircraft and has improved sound absorption properties.

1. An aircraft cabin plate absorber for sound absorption in an aircraft cabin, comprising: a supporting panel,a cover panel; andan intermediate layer arranged between the supporting panel and the cover panel;wherein the cover panel is arranged on the supporting panel on the side facing the sound inside a cabin space;wherein the cover panel comprises a cover layer visible from the cabin space;wherein the supporting panel is formed so as to hold the cover panel and wherein the cover panel is fastened to the supporting panel by the intermediate layer;wherein the cover panel comprises at least one connecting region, in which connecting region, the cover panel is connected to the supporting panel, and at least one absorption region, in which absorption region, the cover panel is configured to oscillate with respect to the supporting panel;wherein the intermediate layer adhesively connects the supporting panel to the cover panel in the at least one connecting region; andwherein the intermediate layer is in the form of a continuous layer comprising at least one recess, the at least one recess forming the at least one absorption region. 2. The plate absorber according to claim 1, wherein the supporting panel comprises a core layer and a first cover layer, the first cover layer being arranged facing away from the sound field in the cabin space and the core layer having uniformly formed tubular or honeycombed cells extending openly, continuously over the thickness of the core layer, and mutually separated by cell walls. 3. The plate absorber according to claim 2, wherein the core layer comprises a matrix prepreg connected to the core layer, on the side facing the intermediate layer. 4. The plate absorber according to claim 1, wherein the intermediate layer comprises a plurality of mutually spaced connecting regions, so as to connect the cover panel to the supporting panel in the connecting regions. 5. The plate absorber according to claim 1, wherein the intermediate layer comprises a foamed material layer or non-woven fabric layer, wherein the entire surface of the foamed material or the non-woven fabric layer being connected to the supporting panel and the cover panel, andwherein the intermediate layer has a low compression rigidity. 6. The plate absorber according to claim 1, wherein the cover panel comprises a cover panel core layer and a second cover layer connected to the cover panel core layer, wherein the second core layer is arranged facing the sound field. 7. The plate absorber according to claim 1, wherein the cover panel comprises a laminate supported on the supporting panel via the connecting regions. 8. A device for sound absorption in an aircraft cabin, in which the cabin space is enclosed at least in part by an internal space facing the cabin space, the device comprising a plurality of panels, wherein at least one of the panels comprises a plate absorber, the plate absorber comprising: a supporting panel,a cover panel; andan intermediate layer arranged between the supporting panel and the cover panel;wherein the cover panel is arranged on the supporting panel on the side facing the sound inside a cabin space;wherein the cover panel comprises a cover layer visible from the cabin space;wherein the supporting panel is formed so as to hold the cover panel and wherein the cover panel is fastened to the supporting panel by the intermediate layer;wherein the cover panel comprises at least one connecting region, in which connecting region, the cover panel is connected to the supporting panel, and at least one absorption region, in which absorption region, the cover panel is configured to oscillate with respect to the supporting panel;wherein the intermediate layer adhesively connects the supporting panel to the cover panel in the at least one connecting region; andwherein the intermediate layer is in the form of a continuous layer comprising at least one recess, the at least one recess forming the at least one absorption region. 9. An aircraft comprising a cabin space arranged inside the fuselage comprising a device for sound absorption, the device comprising a plurality of panels, wherein at least one of the panels comprises a plate absorber, the plate absorber comprising: a supporting panel,a cover panel; andan intermediate layer arranged between the supporting panel and the cover panel;wherein the cover panel is arranged on the supporting panel on the side facing the sound inside a cabin space;wherein the cover panel comprises a cover layer visible from the cabin space;wherein the supporting panel is formed so as to hold the cover panel and wherein the cover panel is fastened to the supporting panel by the intermediate layer;wherein the cover panel comprises at least one connecting region, in which connecting region, the cover panel is connected to the supporting panel, and at least one absorption region, in which absorption region, the cover panel is configured to oscillate with respect to the supporting panel;wherein the intermediate layer adhesively connects the supporting panel to the cover panel in the at least one connecting region; andwherein the intermediate layer is in the form of a continuous layer comprising at least one recess, the at least one recess forming the at least one absorption region.
