Evaluation between Virtual Acoustic Model and Real Acoustic Scenarios for Urban Representation

Abstract

Audio representation is critical for immersive virtual environments. This article presents a quasi-experiment based on architecture students evaluating the immersive impact of 3D audio in the representation of urban environments. In the framework of acoustic urban heritage preservation, a set of city squares with varying acoustic features were used as case studies in a two-step process: an objective analysis of the acoustic properties of these spaces; and the users' subjective perceptions of the virtual environment of the squares. The study shows that we can gain a better understanding of the objective parameters through the subjective views of users. Acoustic heritage can be assessed subjectively using an immersive system such as virtual reality, in which audio representation is a key factor.
