DESCRIPTION:Traffic noise due to tyres rolling on road surfaces is a signi
 ficant cause of irritation and distress. It arises from tyre vibrations ca
 used by the impact of tread elements on road asperities. This process is d
 ifficult to model\, demanding as it does time-domain simulations of a rand
 om contact process. Hence it is desirable to simplify individual component
 s\; the tyre belt\, for example\, is often represented as a thin plate. Th
 e talk is concerned with the viability of this approximation. We consider 
 waves propagating on an infinite plate with composition typical of a tyre 
 belt. This case admits exact solutions for the freely propagating waves th
 at can be sustained. On the basis of their dispersion relations\, we asses
 s the applicability of thin-plate theories\, and also approximate thicknes
 s-resolving calculations\, to tyre vibration modelling.
