Abstract

This paper provides a small set of essential parameters for a personalized and effective real-time auralization with headphones. An image-guided procedure with two 2D images of the user's head guides the mixed structural modeling of head-related transfer function (HRTF), combining a spherical head model with ear displacement with the HRTF high-frequency magnitude selected from a database according to ear anthropometry. Room acoustics phenomena are simplified following the scattering delay network (SDN) approach which allows an accurate spatialization of first order reflections. Finally, statically significant improvements in localization performances within a virtual reality (VR) test allow to identify some benefits of the proposed customized auralization model compared to the widely used higher-order ambisonics (HOA) rendering with generic HRTFs.
