|Synonyms||Select sound sensitivity syndrome, sound-rage|
|People who are sensitive to certain sounds sometimes cope by blocking them out.|
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.
Misophonia is not classified as an auditory or psychiatric condition, there are no standard diagnostic criteria, and there is little research on how common it is or the treatment. Proponents suggest misophonia can adversely affect the ability to achieve life goals and to enjoy social situations. Treatment consists of developing coping strategies through cognitive behavioral therapy and exposure therapy.
Signs and symptoms
As of 2016 the literature on misophonia was 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, slurping, chewing or popping gum, whispering, 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, 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 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.
Misophonia's mechanism is not known, but it appears that, like hyperacusis, it may be caused by a dysfunction of the central auditory system in the brain and not of the ears. The perceived origin and context of the sound appears to be essential to trigger a reaction.
There are no standard diagnostic criteria. Misophonia is distinguished from hyperacusis, which is not specific to a given sound and does not involve a similar strong reaction, and from phonophobia, which is a fear of a specific sound, but it may occur with either.
The diagnosis of misophonia is not recognized in the DSM-IV or the ICD 10, and it is not classified as a hearing or psychiatric disorder. It may be a form of sound–emotion synesthesia, and has parallels with some anxiety disorders. As of 2015 it was not clear if misophonia should be classified as a symptom or as a condition.
There are no evidence-based treatments for the condition; health care providers generally try to help people cope with it by recognizing what the person is experiencing, and by working on coping strategies with the person. Some small studies have been published on the use of sound therapy similar to tinnitus retraining therapy and on cognitive behavioral therapy and particularly exposure therapy, to help people become less aware of the trigger sound. None of these approaches have been sufficiently studied to determine their effectiveness.
The term "misophonia" was first coined by audiologists Pawel and Margaret Jastreboff in a publication in 2001.

- Quote from Cavanna 2015: "If confirmed by future systematic studies in large populations, the presence of high rates of comorbidity would go against the argument that misophonia should be labeled as a primary diagnosis. In fact, it would suggest that it is a symptom manifestation of other underlying or comorbid diagnoses and should more appropriately be labeled as a symptom, rather than as a stand-alone diagnosis. Either way, the addition of misophonia to nosographic classification systems of psychiatric disorders, such as the DSM, would require careful consideration."
