This paper clarifies effect of the synchronous angular speed of a Steerable dummy head in direction judgment of horizontal sound source. We conducted direction judgment experiments using dynamic binaural signals recorded with a Steerable dummy head of which synchronous rotation angular speed was modified by 0.1, 0.5, -0.5 and -1.0 of a listener's head rotation angular speed. The mean direction judgment performances of 4 listeners, who had served as listeners for sound localization experiments using dynamic binaural signal recorded by a Steerable dummy head, tests were over 70% for any synchronous speed modification rates. The performances are significantly better than that of the head-still condition. This result suggests that an accurate head tracking is not necessarily required for the dynamic binaural sound reproduction system.
