KRYLOV, V.V., 2004. Simplified reduced-scale modelling of vehicle interior noise. Proceedings of the 33rd International Congress and Exposition on Noise Control Engineering (Inter-Noise 2004), Prague, Czech Republic, 22-25 August 2004.
The present paper gives a review of the recent research into simplified reducedscale
models of automotive structures that can be used for prediction of structure-borne vehicle
interior noise. The models under consideration evolve from the simplest ones to more
sophisticated developments and take into account different structural dynamic and acoustic
features of real vehicles. Analytical and numerical approaches to the theoretical description of
such models are discussed. The comparison of the theory with the measurements on some
physical reduced-scale models demonstrates that such models can be used successfully for
studying interior noise in real road vehicles. One of the most important issues in this technique is
to find a compromise between the minimum degree of complexity of a model and the required
accuracy of description of frequency contents and noise levels in a real vehicle. It is expected that
the proposed methodology will lead to the development of efficient analytical and experimental
tools that could be used for prediction of vehicle interior noise on a design stage.
