摘要：
A sandwich element for the sound-absorbing inner cladding of means of transport such as an aircraft. The sandwich element includes a three-dimensionally constructed core structure disposed between two cover layers that run substantially parallel to one another at a distance. A plurality of passages for sound transmission are incorporated in the core structure and/or in at least one cover layers, wherein at least one sound absorption layer is disposed in the area of at least one cover layer at least in parts.
