Invisible architecture, communicating space through sound models

For years now, the increasing development of virtual reality technologies and digitisation processes in architecture has been leading cultural heritage communication towards an increasingly sustainable and inclusive approach. In this sense, the accumulation of data and, consequently, of specific information that the models bring with them, offers the opportunity for numerous insights related to the conversion of parameters to achieve an even broader communication towards users with perceptual limitations. The topic of perception, although now intrinsic in the fundamental criteria of architectural design, may receive less public attention compared to more immediate issues like building accessibility. From a practical point of view, the most innovative technologies to improve the quality of life of blind subjects come mainly from neuroscience laboratories, also and above all to assess the impact of so-called sensory substitutional devices on brain activity. What is presented in this study is therefore to extend what are the operating principles of the above-mentioned tools and contextualise them within the domain of the perception of valuable architectural space, for an understanding of geometry and proportion through sound.
