An aircraft cabin panel for sound absorption, with a sandwich
construction, comprising a core layer that comprises a plurality of
tube-like or honeycomb-like cells that extend in an open manner across
the thickness of the core layer and that are separated from each other by
cell walls and that are uniform in design. A first cover layer faces away
from the sound field, as well as a second cover layer that faces towards
the sound field and that comprises a plurality of perforation holes and
adjacent cells are interconnected by way of apertures in the cell walls.
The perforation of the second cover layer comprises a distance (b)
between holes, which distance exceeds the opening width (c) of the cells
of the core layer, wherein the first cover layer is closed and wherein
the cell walls comprise a perforation so that they are acoustically
transparent in the direction parallel to the cover layers.
