In times of progressive urbanization, a growing section of the human population is exposed to noise pollution. The rising request for mobility enlarges the problem by adding more sound sources to the acoustic environment, e.g. due to public transportation, air traffic, private transport etc. As a consequence, more and more individuals are affected by environmental noise and hence a growing countermovement against large-scale projects can be observed. In order to introduce ways to ease understanding of noise pollution effects, auralization of virtual situations can be of great advantage. The possibility to listen to an acoustic simulation, e.g. of a significant intervention into the infrastructure in a metropolitan area, can be a powerful tool to inform persons affected that is already available in an early project stage. Therefore, auralization represents a preventive measure that can involve non- experts to intuitively experience consequences of urban modification with their hearing sense, and without the need of numbers and figures that are difficult to comprehend. To bring this concept of virtual acoustic reality into existence, some large gaps have to be overcome. This contribution will discuss problems and potential solutions towards new applications of auralization.
