An engine compartment casing element (1), in particular for sound absorption, with a foamed material element (2) attached to a wall element (3) which is preferably reverberant, the foamed material element (2) having a skin-like covering (5) on the side facing away from the wall element (3). The foamed material element (2) is perforated, the foamed material element (2) is also covered on both sides with an air-impermeable plastic sheeting (5) or (6) respectively which also covers the perforated areas (holes 4), and the foamed material element (2) is installed so that it runs at least in part at a distance (a) from the wall element (3).
