Abstract: The goals of this research are to study to what extend the air in the narrow geometry between tyre and road will influence the vibrations and sound radiation of the tyre. To achieve these goals two different models are made using the "low reduced frequency model " described by Beltman. The first model consists of a patch vibrating just above the ground and the second model consists of a patch vibrating inside a tube. Both models are used in combination with input data from measurements and calculations to study the effect for different mechanisms that play a role in tyrelroad noise. The main concliwions axe that the air in the narrow geometry has an effect on the vibration---of the tyre and that the radiated somd is not directly affected by the narrow geometry, but indirectly by the change of the vibration of the patch due to the narrow geometry. Acknowledgements I want to thank the whole Department of Applied Acoustics in Sweden for the great support and the nice environment. I especially wmt to tha & Patrik hdersson for his supervision.
