Misophonia

Misophonia, literally "hatred of sound," was proposed in 2000 as a condition in which negative emotions, thoughts, and physical reactions are triggered by specific sounds. It is also called "select sound sensitivity syndrome" and "sound-rage." Misophonia has no classification as an auditory, neurological, or psychiatric condition, there are no standard diagnostic criteria, it is not recognized in the DSM-IV or the ICD-10, and there is little research on its prevalence or treatment. Proponents suggest misophonia can adversely affect ability to achieve life goals and to enjoy social situations. Treatment consists of developing coping strategies such as cognitive behavioral therapy and exposure therapy.

The diagnosis of misophonia is not recognized in the DSM-IV or the ICD 10, and it is not classified as a hearing, neurological, or psychiatric disorder. It may be a form of sound–emotion synesthesia, and has parallels with some anxiety disorders.

As of 2016 the literature on misophonia was very limited. 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. It also appears that a misophonic reaction can occur in the absence of an actual 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.
