The paper describes the application of the earlier proposed simplified analytical approach to the modelling of structural vibration and structural-acoustic coupling in thin-walled elastic structures for calculations of structure-borne interior noise in an aircraft cabin. The structural simplification is based on understanding the processes of generation of influential modes of structural vibration at particular frequencies and of sound radiation by vibrating surfaces into the interior. Analytical results are illustrated by calculations of resonance frequencies of acoustic and structural modes, of their coupling coefficients and of the resulting structure-borne interior noise.
