Combining VR Visualization and Sonification for Immersive Exploration of Urban Noise Standards

摘要: Urban traffic noise situations are usually visualized as conventional 2D maps or 3D scenes. These representations indispensable tools to inform decision makers and citizens about issues of health, safety, quality life but require expert knowledge in order be properly understood put into context. The subjectivity how we perceive well the inaccuracies common calculation standards rarely represented. We present a virtual reality application that seeks offer an audiovisual glimpse background workings one these standards, by employing multisensory, immersive analytics approach allows users interactively explore listen approximate rendering data same environment simulation occurs in. In for this useful, it should manage complicated level calculations real time run on commodity low-cost VR hardware. prototypical implementation, utilized simple interactions current mobile headsets combined them with techniques from visualization sonification allow road real-time urban environment. levels were calculated over CityGML LoD2 building geometries, accordance Common Noise Assessment Methods Europe (CNOSSOS-EU) sound propagation methods.
