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

Today’s new pipeline projects have to meet countless technical, regulatory, economic, or social requirements before they can go from the drawing board to reality. One of the more recent considerations is in the area of environmental noise. Environmental noise from pipeline facilities is particularly difficult to control because of the complexities of sound propagation and the subjective nature of that sound relative to some receptor. The extent of noise control from facility equipment such as compressors, coolers, piping, valves, blowdown, emergency flares, even telephone horns, therefore, becomes very difficult to estimate. There must be some understanding of baseline expectations from all interested parties. In addition, pipeline operators must treat environmental noise control as an integral part of project concept and design and not as an afterthought or additional non-core responsibility. Environmental noise control is not an additional cost, it is part of the overall cost of the pipeline transportation business.
