The increased focus on road traffic noise has intensified the research activities concerning the investigation of tyre/road noise generation as one of the major noise sources. While during the seventies and eighties research effort considered mainly the understanding of phenomena behind the generation processes, today, prediction methods are the main subject of ongoing activities. These prediction methods differ with respect to philosophy and approach. They cover the wide range from FE approaches, modelling details as exact as possible, to statistical approaches quantifying the influence of main parameters influencing tyre/road noise. The following work focuses on a quasi-three dimensional model for the prediction of tyre/road noise. The model is based on the description of the main physical properties of tyres, the contact between tyre and road and the radiation from tyres. It includes the properties of the road surface. By means of this model possibilities and limitations of tyre/road noise modelling can be discussed with respect to the required quality of the input data. The results from the model are compared with coast-by measurement for tyres on surfaces with different properties.
