Abstract: This study presents the development of a high-fidelity coupled structural–acoustic finite element model
of the Piaggio P.180 passenger cabin. The work aims to predict interior noise in the low- to mid-frequency
range. To reduce computational cost, the fuselage was modeled using two-dimensional shell elements and
one-dimensional beam elements. A detailed modal analysis accurately captured the cabin’s resonance behavior:
the first three structural modes showed good agreement with experimental data. Finally, harmonic response
analyses were performed to evaluate the noise reduction through the airframe up to approximately 110 Hz.
