Abstract (en)
[origin: EP3002405A2] According to the invention, there is provided a silencing arrangement for installation (11) in a through opening in a window frame or in another opening through a separating surface. The arrangement comprises a plurality of air channels (14) which extend along the entire or substantially the entire depth of the silencing arrangement, which air channels are separated by sound absorbing elements (13) which are fixated relative each other. A first end of each of at least two of the sound absorbing elements has another width than the respective other end. The at least two sound absorbing elements of the sound absorbing elements are alternately arranged such that every other of these at least two sound absorbing elements taper in the depth direction of the silencing arrangement, and the remaining of these at least two sound absorbing elements expand in the depth direction, thereby making at least one of the air channels disposed at an angle relative the depth direction of the silencing arrangement.
