发明名称 PANNEAU D'HABILLAGE INSONORISANT ET AERONEF
摘要 A self-supporting acoustic insulation panel (1) comprising a visible wall (3) that is not self-supporting and an invisible wall (2) that is not self-supporting facing a source (50) of soundwaves. A porous core (20) is arranged between the visible wall (3) and the invisible wall (2), a plurality of link elements (5) each extending from the invisible wall (2) towards the visible wall (3), each link element (5) passing through an orifice (21) in said core (20) and being connected to the visible wall (3) and to the invisible wall (2), each link element (5) separating the visible wall (3) from the invisible wall (2) and mechanically linking the visible wall (3) with the invisible wall (2) while acoustically decoupling the visible wall (3) from the invisible wall (2).
