Your eyes can override your ears about where a sound is coming from

In the ventriloquist effect, a sound and a visual event occur in slightly different places, a dummy's moving mouth, a TV screen, a bouncing ball, and most people perceive the sound as coming from wherever they see the matching motion instead of its true source. Vision usually wins this tug-of-war because it localizes space more precisely than hearing does. Psychologists Ian Howard and William Templeton gave the effect its first rigorous study in 1966.
