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.en620 Ingenieurwissenschaften und zugeordnete Tätigkeiten780 Musik534 Schall und verwandte Schwingungenbinaural room impulse responsesBRIRauralizationhead movementstimulusnoiseHRTFConference Object
