    EnvironZen: Immersive Soundscapes via Augmented Footstep Sounds in Urban Areas
    (i-com: Vol. 21, No. 2, 2022) Schrapel, Maximilian; Happe, Janko; Rohs, Michael
    Urban environments are often characterized by loud and annoying sounds. Noise-cancelling headphones can suppress negative influences and superimpose the acoustic environment with audio-augmented realities (AAR). So far, AAR exhibited limited interactivity, e. g., being influenced by the location of the listener. In this paper we explore the superimposition of synchronized, augmented footstep sounds in urban AAR environments with noise-cancelling headphones. In an online survey, participants rated different soundscapes and sound augmentations. This served as a basis for selecting and designing soundscapes and augmentations for a subsequent in-situ field study in an urban environment with 16 participants. We found that the synchronous footstep feedback of our application EnvironZen contributes to creating a relaxing and immersive soundscape. Furthermore, we found that slightly delaying footstep feedback can be used to slow down walking and that particular footstep sounds can serve as intuitive navigation cues.

    Towards extended reality soundwalks as community noise communication tool
    (EnviroInfo 2022, 2022) Petersen, Iwer
    Noise is getting increasing attention as environmental factor. Communication of potential impact to affected citizens is part of a participatory approach to many projects like e.g., in windenergy projects. Sound, however, is hard to grasp by non-specialists looking at commonly used metrics. Noise maps from sound simulations are often used to communicate expected noise levels from certain sources but only provide abstract insights that still can be hard to transfer for nonexperts. Extended reality (XR) in combination with real-time spatial audio allows to explore the impact of future projects in the built environment as a direct experience. While the generation of a visual environment poses no greater challenge by using geospatial data, realistic modelling of a spatial soundscape from multiple point-sound-sources is not trivial. This paper reflects on the challenges to present an audio-visual windfarm in XR, outlines established techniques that have proven useful as well as challenges and opportunities in creating, delivering, and evaluating virtual soundscapes.
