Abstract:
1. A method of modifying an acoustic comfort of an aircraft cabin of an aircraft, at least a part of the aircraft cabin being delimited by trim panels, the aircraft cabin comprising a system for active noise control of ambient noise inside the aircraft cabin, the method comprising: converting between a first configuration of the aircraft cabin and a second configuration of the aircraft cabin, wherein: in the first configuration at least one trim panel of the trim panels is an active panel having actuators powered by the system for active noise control, said active panel being connected to a cabling for supplying power to the active panel, said cabling being arranged in the aircraft to power each active panel installed in the first configuration of the aircraft cabin by a power system for supplying power to each active panel, in the second configuration the at least one trim panel of the trim panels is a passive panel without any actuators, during a conversion from the first configuration to the second configuration, the active panel is removed and the passive panel is substituted for the active panel for the at least one trim panel, with which it is mechanically interchangeable, each removed active panel being disconnected from the system for active noise control and the cabling powering each removed active panel remaining on board of the aircraft, the cabling for supplying power to the removed active panel which is substituted by the passive panel being fixed by a socket on a dummy connector of the passive panel, and during a further conversion from the second configuration to the first configuration, the passive panel is removed and the active panel is substituted for the passive panel, with which it is mechanically interchangeable, and is connected to the system for active noise control by the cabling on board of the aircraft.
