Sound-absorbing panel

Abstract

Sound-absorbing panel (1) comprising a contact surface (2) in contact with a wall (A) to be sound-insulated, and an externally visible surface (3) opposite the contact surface (2); characterized in that it comprises a section (4) which is movable relative to the panel (1) between a state moved away from the panel (1) to define a blind cavity (5) on the externally visible surface (3), and a state moved closer to the panel (1) to be inserted into the cavity (5); wherein, in the away state, the section (4) allows the insertion of a screw (6) into the cavity (5) to connect the panel (1) to the wall (A); wherein the section (4) is formed integrally with the panel (1); wherein the section (4) has a substantially prismatic shape with a triangular cross-section;wherein the section (4) has an outer surface (4a) which, in the closer state, is coplanar to the externally visible surface (3) of the panel (1); wherein the cavity (5) has two side surfaces (5a) which converge towards an inner region of the panel (1).
