Hypervigilance is the state of responding in an exaggerated manner to sudden stimuli. Hypervigilant people are in a state of higher stress than normal, and react more strongly when a sudden noise startles them. Often, this response is caused by previous trauma such as being in a war or being abused as a child.
When you hear a sudden loud noise, your nervous system responds immediately, activating the fight-or-flight response. This triggers the sympathetic branch, releasing adrenaline and other stress hormones, which prepare your body for rapid action. Physiological changes occur, such as increased heart rate and heightened alertness, allowing you to react quickly to potential danger. This automatic response is a crucial survival mechanism.

The phenomenon can be explained by the concept of sensory adaptation and the principles of signal detection theory. In a quiet room, a person's auditory system is more sensitive to sudden sounds due to the lack of background noise, making them more likely to perceive and react to the knock as a significant stimulus. Conversely, in a louder environment, the background noise can mask sudden sounds, leading to a diminished startle response.
