The Eardrums Move When The Eyes Move

When the eyes move left, both eardrums initially move right and then oscillate for three to four cycles, with another one to two cycles occurring after the eye movement is complete. Eye movements in the opposite direction produce an oscillatory pattern in the opposite direction. This is present in both human and nonhuman primates and appears similar across both ears.
The impact of the eye movement-related process revealed here on subsequent auditory processing remains to be determined.
