Misophonia, is a disorder that has to do with someone hating sounds. It is a purported disorder in which negative emotions, thoughts, and physical reactions are triggered by specific sounds. Misophonia has no evidence-based research on its prevalence or treatment.
As of 2014 there was no evidence-based research available on misophonia. Some small studies show that people with misophonia generally have strong negative feelings, thoughts, and physical reactions to specific sounds, which the literature calls “trigger sounds.” These sounds are apparently usually soft, but can be loud. One study found that around 80% of the sounds were related to the mouth (eating, yawning, etc.) and around 60% were repetitive. A visual trigger may develop related to the trigger sound.
Reactions to the triggers can include aggression toward the origin of the sound, leaving, or remaining in its presence but suffering, trying to block it, or trying to mimic the sound.
The first misophonic reaction may occur when a person is young, and can originate from someone in a close relationship, or a pet.
People with misophonia are aware they experience it and that it is not normal; the disruption it causes to their lives ranges from mild to severe.
