N2 - Sound in Virtual Reality (VR) has been explored in a variety of algorithms which try to enhance the illusion of presence, improving sound localization and spatialization in the virtual environment. As new systems are developed, different models are applied. There is still the need to evaluate and understand the main advantages of each of these approaches. In this study, a performance comparison of two methods for real-Time 3D binaural sound tested preferences and quality of presence for headphones in a VR experience. Both the mathematical based HRTF and the convolution based measured HRTF from the MIT KEMAR show a general similarity in the participants sense of localization, depth and presence. Nevertheless, the tests also indicate a preference in elevation perception for the convolution-based measured HRTF. Further experiments with new tools, techniques, contexts, and guidelines are therefore required to highlight the importance and differences between these two methods and other implementations.
