Within the framework of the European project SVEN (Sound Quality of Vehicle Exterior Noise) tools and methods will be developed to improve the situation of traffic noise in cities and suburbs. In order to achieve this aim, the effects of vehicle noise on human hearing have to be explored. Suitable measurements and analyses are used for the objective description of vehicle exterior noises and traffic noises correlating with the subjective judgement and the physiological effects. This paper introduces a hybrid model for the calculation of binaural vehicle exterior noises. The model uses recordings of the main excitation signals (engine, intake, exhaust system, tires) and binaural filters describing the transfer paths from the sources to an artificial head standing at a distance of several meters outside the vehicle. The calculation method allows the simulation of various driving situations. An application example is used to show the effects of the partial sound events on the entire vehicle exterior noise.
