The core (50) is made of a material whose rigidity is lower than the rigidity of each of the skins, and in that at least the first skin (10) has on its internal face (15) first protrusions (30) which penetrate into the core (50) and which are separate from the second skin (20), the first protrusions (30) being arranged irregularly on the internal face (15) and/or presenting variable geometries from one first protrusion (30) to another first protrusion (30), such that the transmission of acoustic waves through the wall is minimized.",
