A gun is used to start sprinters, instead of a flash, because you can react faster to a bang than to a flash. Physiology behind it: the cells in your auditory cortex can change their firing rate more quickly in response to a bang than your visual cortex cells can in response to a flash.

Counter intuitive since light travels faster than sound. Or does it?
