This work presents a high-frequency vibro-acoustic modelling approach for predicting aircraft cabin noise induced by Turbulent Boundary Layer (TBL) excitation. The wall-pressure loading is represented using a semi-empirical spectrum combined with a spatial coherence reduction, enabling the construction of a physically consistent distributed surface source. The interior acoustic field is computed through a radiative energy transfer formulation in which each boundary element acts as an emitting–receiving patch, with energy exchanges governed by geometric visibility and local absorption. Numerical results obtained on a representative fuselage section show smooth and physically consistent energy distributions inside the cabin, reflecting the spatial variation of the aerodynamic excitation and the influence of the interior surfaces. The proposed method offers an efficient and physics-informed tool for early-stage cabin acoustic assessment and provides a basis for future optimisation developments.
