Abstract:
In the year 2014 the working group for Audio Communications was established at the Institute of Communications Technology at Leibniz Universität Hannover. Several research projects in audio signal processing for VR&MR, perception and modelling of complex auditory phenomena like multi source localization, externalization, sound annoyance and immersion in music have been conducted and successfully completed since then. Advanced measurement methods have been conceived and evaluated starting from perceived occlusion and transparency in headphone VR binaural rendering relating to the acoustical headphone impedance seen from the ear as well as describing the perceived degree of musical immersion or wind turbine noise annoyance with higher order sound field parameters gathered with Eigenmike or artificial head.Most of the groups acoustical, psycho-acoustical AR & VR experiments have been conducted in our acoustically treated Immersive Media Lab equipped with more than 40 monitor loudspeakers, motion tracking system and U-shaped video near field projection units. This experimental site allows us to establish controlled listening conditions, audio-video interaction and investigate co-presence perception in virtually connected rooms under audio transmission delay as well as multichannel feedback suppression schemes. This talk introduces to our audio and acoustic research facilities and provides an overview of selected project results.
