The invention relates to a covering (22) of a fuselage (1) for aircraft comprising propeller engines (3) comprising an opening (12) which is surrounded by a structural frame formed by the ribs (5) and the stringers (6) of the aircraft around the area of maximum acoustic impact of the propeller engines (3), said opening (12) further comprising a non-structural panel (7) joined to the previous structural frame by means of a rather non-rigid joint which considerably attenuates the vibrations through such joint, thus reducing the indirect acoustic noise and the indirect structural noise generated by the propeller engines (3) inside the passenger cabin of the aircraft. An acoustically attenuated fuselage covering comprises an opening which is surrounded by a structural frame formed by stringers and frames/ribs of the aircraft around an area of maximum acoustic impact of the propeller engines.
