KRYLOV, V.V., GEORGIEV, V.B. and GORMAN, R., 2004. Recent progress in reduced-scale modelling of vehicle interior noise. IN: Sas, P. (ed.). Proceedings of the International Conference on Noise and Vibration Engineering (ISMA 2004), Leuven, Belgium, 20-22 September 2004, pp.3837-3850.
The paper gives a review of the recent research into simplified reduced-scale models of structure-borne
vehicle interior noise carried out in Loughborough University. The models under consideration evolve
from the simplest ones to more sophisticated developments that take into consideration some important
structural dynamic and acoustic features of real vehicles. Analytical and numerical approaches to the
theoretical description of such models are discussed. The results of theoretical calculations are compared
with the measurements on some reduced-scale models. The comparison of the theory with the
measurements demonstrates that simplified reduced-scale models can be used successfully for studying
interior noise in real road vehicles. One of the most important issues in this approach 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.
