The soundscape design tool City Ditty has been supplemented with local data from Santiago, Chile, which will be used as part of a multi-year biophilic design intervention of an urban park where the perception of natural soundscapes dominates over other sound sources. These methodologies are documented so that others may understand the benefits of such novel tools and encourage others to do the same in their own communities. Teams must: 1) understand the design goals and the existing space; 2) create a 3D model of the space; 3) collect audio recordings that represent the space (i.e., ambient background recordings and dry recordings of individual sound sources); 4) collect 3D models that represent relevant sound sources (e.g., regional birds); 5) integrate these with City Ditty, which provides an accessible soundscape design interface that works on both desktop PC and Head-Mounted VR; 6) design, evaluate, and implement! For this project, a biophilic design competition is planned with interdisciplinary teams which will be evaluated through individual auralization tests. The design proposal whose soundscape gets the highest rating will be optimized by iterating listening tests and adjusting the design parameters. Current progress on the project and a working demo of the simulations is presented.
