An aircraft includes at least one net for reducing aerodynamic noise from a structural element of the aircraft. The flexible net associated with the structural element is retractable and capable of occupying at least one position located between the following two end positions: a deployed position, in which the net is placed in a turbulence area, and a retracted position, in which the net is at least partially outside the turbulence area. The net may be automatically moved between positions based on an aircraft parameter such as speed or altitude.
