Claim:
1. A room delimitation element, comprising: a through opening, which extends through the entire room delimitation element in a thickness direction of the room delimitation element; and an insert, which is disposed in the through opening and which extends across the entire through opening in a transverse direction that is perpendicular to the thickness direction of the room delimitation element, wherein the insert comprises at least one air-passage region and at least one sound absorption region; wherein the at least one sound absorption region is disposed next to the air-passage region in a vertical direction, said vertical direction is perpendicular to the thickness direction and the transverse direction of the room delimitation element; wherein the at least one sound absorption region comprises at least one sound absorption element implementing a sound absorption effect in the vertical direction of the room delimitation element; wherein the at least one air-passage region comprises at least a first layer of a plurality of sound reflection elements and a second layer of a plurality of sound reflection elements spaced apart in the thickness direction of the room delimitation element; wherein the sound reflection elements of the first layer are mutually spaced apart in the vertical direction of the room delimitation element and the sound reflection elements of the second layer are mutually spaced apart in the vertical direction of the room delimitation element, such that a vacant space is provided between every two vertically adjacent sound reflection elements; and wherein the sound reflection elements of the first layer and the sound reflection elements of the second layer mutually offset and partially overlap one another in the vertical direction of the room delimitation element, such that no rectilinear passage extending through the insert is formed in the thickness direction of the room delimitation element.
