Room delimitation element

A room delimitation element, having a through opening which in a thickness direction of the room delimitation element extends through the entire room delimitation element;

• and an insert which is disposed in and/or ahead of the through opening and which in directions which are transverse to the thickness direction of the room delimitation element extends in each case at least across the entire through opening, wherein the insert has at least one air-passage region in the region of the through opening and at least one sound absorption region, wherein the at least one sound absorption region is disposed beside the air-passage region in a direction which is transverse to the thickness direction of the room delimitation element;
• the at least one sound absorption region has at least one sound absorption element which has a sound absorption effect in a direction which is transverse to the thickness direction of the room delimitation element;
• and the room delimitation element has at least one clearance which adjoins the through opening in a direction which is transverse to the thickness direction of the room delimitation element;
• and at least one of the at least one sound absorption regions of the insert is at least partially disposed within at least one of the at least one clearances, and the at least one air-passage region in the thickness direction of the room delimitation element has at least two layers of a plurality of sound reflection elements, wherein the sound reflection elements in one layer are in each case mutually spaced apart in a direction which is transverse to the thickness direction of the room delimitation element and the sound reflection elements in different layers are disposed so as to be mutually offset in a direction which is transverse to the thickness direction of the room delimitation element.
