Ever wonder why your immediate reaction to a loud noise is shutting your eyes? You hear a loud noise and immediately flinch or squeeze your eyes shut tight. This automatic response happens at the first sign (or sound) of danger; this act of mechanically blinking your eyes is known as acoustic startle reflex.
Misophonia is a disorder in which certain sounds trigger emotional or physiological responses that some might perceive as unreasonable given the circumstance. Those who have misophonia might describe it as when a sound “drives you crazy.” Their reactions can range from anger and annoyance to panic and the need to flee.
