The invention relates to a sound-absorbing element (10) comprising a cover layer (2, 2.2) having a micro perforation (21); a substrate layer (1) having a plurality of through-passages (11), such as in particular bores or slots; and an intermediate layer (3, 3.2), which holds the cover layer (2) spaced apart from the substrate layer (1), wherein the intermediate layer (3, 3.2) is designed to create a communicating connection between the micro perforation (21) of the cover layer (2) and passages (11) in the substrate layer (1) in order to produce a sound-absorbing effect. |
