the literature on<unk>  was limited. Some small studies show that people with<unk>  generally have strong negative feelings, thoughts, and physical reactions to specific sounds, which the literature calls "trigger sounds". These sounds usually appear quiet to others, but can seem loud to the person with<unk> , as if they can't hear anything except the sound. One study found that around 80% of the sounds were related to the mouth (e.g., eating, slurping, chewing or popping gum, whispering, whistling) and around 60% were repetitive. A visual trigger may develop related to the trigger sound, and a<unk>  reaction can occur in the absence of an actual sound. Reactions to triggers can range from mild (anxiety, discomfort, and/or disgust) to severe (rage, anger, hatred, panic, fear, and/or emotional distress). Reactions to the triggers can include aggression toward the origin of the sound, leaving, remaining in its presence but suffering, trying to block it or trying to mimic the sound. The first<unk>  reaction may occur when a person is young, often between the ages of 9 and 13, and can originate from someone in a close relationship, or a pet. People with<unk>  are aware they experience it and some consider it abnormal; the disruption it causes in their lives ranges from mild to severe. Avoidance and other behaviors can make it harder for people with this condition to achieve their goals and enjoy interpersonal interactions.
