Abstract
Conclusions. The data suggest that sound lateralization sensitivity during interaural time difference (ITD) discrimination is altered by eccentric gaze and that sound lateralization shifts toward the direction of the gaze. Objective. Using dichotic sounds, the effect of eye position on the orientation of sound lateralization was investigated in humans. Subjects and methods. The subjects were studied by testing ITD discrimination under different conditions of visual fixation. Results: The amplitudes obtained during the ITD discrimination tests during eccentric fixation were significantly greater than those obtained while gazing straight ahead (p<0.05). The median line of amplitude obtained during the ITD discrimination test shifted toward the direction of the gaze.
