Noise maps are key tools of noise protection in urban environments. The expected, averaged noise exposure is visualized for every location within the surveyed area. This visual representation, however, does not allow a statement about the characteristics of the perceived sounds. The aim of this thesis is a real-time simulation of the sound propagation from various sound sources to a receiver in a three-dimensional city model, to make an auralisation of the perceived sounds possible. The size of the city model datasets requires the implementation of optimization approaches, which limit the number of calculated propagation paths and geometric objects, if real-time calculation is to be achieved. Crucial to this is an a-priori analysis of the source signal properties.
