•We reduce a fully coupled structural–acoustic system, under aeroacoustic excitations.•An SEA-like approach is applied and the acoustic response inside the cavity is computed.•A dynamic scheme for the enhancement of the method’s calculation efficiency is proposed.•The results present an excellent co...
