N2 - This study investigated the effect of passive whole-body rotation on the accuracy of listener subjective straight ahead. Listeners sat on a digitally controlled spinning chair placed at the center of a circular loudspeaker array (radius = 1.1 m, speaker spacing = 2.5̊ ) and were exposed to a single 30-ms pink noise burst emitted from one loudspeaker of this array. Under the chair-still condition, listeners were asked to keep their head still, whereas under the chair-rotation condition, listeners were asked to keep their head still and their chairs were rotated at angular velocities of 5, 10, and 20̊/s. In both cases, listeners judged whether the stimulus was presented from the right or left of the subjective straight ahead, and there was a significant decrease in the sound localization accuracies under the chair-rotation condition, while chair rotation speed had almost no effect on sound localization accuracy.
