Why do we blink when we hear loud sound?

This instinctive reaction is called the acoustic startle-reflex eye blink and is part of the protective mechanism we all show in response to potential danger. Loud noises can often mean danger and our eyes need protecting more than most parts of our bodies. This blinking happens faster and harder when people are frightened.
