Inside an anechoic chamber electro-occulographic techniques were used to record the eye movements in 20 subjects who were requested to track with their eyes a steady and continuously moving auditory stimulus. A motor-driven rotary switch made successive contact with 24 loudspeakers mounted side by side in an arc 180° wide and 11 ft in diameter. At angular sound velocities ranging from 15°–180°/sec, the eye movements were recorded under conditions of light and darkness. As the angular velocity of the stimulus increased, the horizontal displacement of the eyes decreased from an average maximum amplitude of 90°–60°. At low velocities, the eye movements followed precisely the position of the sound source. At high velocities (i.e. larger than 130°/sec) mostly saccadic movements were produced. The tracking ability of the eye, judged by the qualitative analysis of the recorded movements, was better in tests performed in the light rather than in darkness.
