HINT-VR is an application for the self-assessment of spatial hearing abilities in VR. The application is described in [1]. The VR peripherals are integrated using the Oculus SDK and audio spatialization is handled using the Unity wrapper [2] for 3D Tune-In Toolkit (3DTI) [3] with far-field measured non-individual HRTFs (Neumann KU100 dummy head) [4].
In the current state, the Hearing in Noise Test (HINT) [5] is implemented using the original stimuli from the German hearing in noise test featuring a male speaker [6].
