DescriptionBeing immersed in an urban environment by means of an audio-visual virtual reality reproduction enables to experience urban environments as they are in reality, or how they could be when for example noise mitigation measures are installed. Virtual reality has become an important tool in the assessment of sound in the urban environment, and its use as a planning tool is increasing. Auralization, a term introduced 25 years ago in analogy with visualization, takes care of the audio part of the virtual reality experience. It was first developed for room acoustic purposes and later applied for urban scenarios as well. This presentation reviews the main components of auralizing urban environments, such as source modelling, propagation modelling and reproduction of sound, and discusses the specific issues that have to be addressed for an authentic auralization, as moving sources and real-time processing. The state-of-the art in auralization for urban environments is presented, as well as expected future developments.
