Effect of auditory stimulation of subjects' chromatic visual fields

The chromatic visual field of 14 subjects was measured while they heard a sound of 1000 Hz at 95 db during 3 min. Stimuli were produced by a monochromator. Visual threshold was lower under the influence of sound for red (lambda = 550 nm) and green (lambda = 610 nm) stimuli at 40 degrees, 45 degrees, and 50 degrees of temporal eccentricity.
