KRYLOV, V., 2003. Analytical modelling of interior noise in aeronautical and automotive structures. Acoustical Physics, 48 (3), 378. 10th International Congress on Sound and Vibration, pp. 2163 - 2170
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.
