This paper describes how Virtual Reality (VR) is used to test the directionality algorithms in headsets and hearing aids. The headset directionality algorithm under test is based on anechoic chamber measurements of microphone impulse responses from a physical headset prototype, with 8 MEMS microphones. The algorithm is imported into Unity3D using the Steam Audio plugin. Audio and video are recorded in different realistic environments with the 4th order ambisonic Eigenmike and the 360-degree Garmin Virb camera. Recordings are imported into Unity3D and audio is played back through headphones using a virtual speaker array. Finally, the combined system is evaluated and tested in VR on human participants.
