ABSTRACT:
A sound absorption element for means of transport, in particular for aircraft, comprising at least one sound absorption panel arranged on a base panel with the base panel comprising a multitude of recesses, in particular a hole grid or the like, for the transmission of sound.According to the invention, the sound absorption panels are each framed by a frame, wherein on the at least one frame at least in some sections a transition profile, in particular to prevent fatigue fractures due to stepwise changes of rigidity between the at least one frame and the base panel is arranged.Due to the base panel comprising a multitude of recesses, in particular comprising a hole grid, in connection with the sound absorption panels an air-permeable sound absorption element can be achieved.
