People who have Misophonia, or selective sound sensitivity syndrome experience (anger, flight, hatred, disgust) triggered by specific sounds. The term was coined by American neuroscientists Pawel Jastreboff and Margaret Jastreboff.
People who have this are most commonly angered by sounds, such as slurping, throat-clearing, people clipping their nails, brushing their teeth, chewing crushed ice, eating, drinking, breathing, sniffing, talking, sneezing, yawning, walking, chewing gum, laughing, snoring, typing on a keyboard, coughing, humming, whistling, singing; saying certain consonants; or repetitive sounds.
Sufferers may also experience such physical symptoms as sweating, muscle tension, and even quickened heartbeat
