Abstract
The present paper gives an overview of the proposed simplified analytical approach to the modelling of structure-born interior noise in aeronautical and automotive structures that could be used for a quick prediction of noise in cars and aircraft. The structural simplification is based on understanding the processes of generation of predominant modes of structural vibration at particular frequencies and of sound radiation by vibrating surfaces into the interior. The approach is illustrated by example calculations of structure-born interior noise and by comparison of the theory with the existing reduced-scale model experiments. It is expected that the proposed approach will lead to the development of more sophisticated but still manageable analytical tools that could be suitable for use on a design stage.
