Abstract: Dynamic binaural synthesis based on binaural room impulse responses (BRIRs) for a discrete grid of head orientations can provide an auralization naturally responding to head movements in all rotational degrees of freedom. Several experiments have been conducted in order to determine thresholds of just detectable BRIR grid resolution for all three rotational directions of head movements using an adaptive 3-AFC procedure. Different audio stimuli as well as BRIR datasets measured in different acoustic environments were used. The results obtained reveal a high sensitivity of listeners towards discretization effects not only in horizontal, but also in vertical and lateral directions. Values indicate a minimum spatial resolution necessary for a plausible binaural simulation of acoustic environments.
