“Information on the prevalence of misophonia in the population is vague, probably due to the lack of consensus in terminology, definition and even in the form of evaluation”, according to Fúlvia Eduarda da Silva in her master’s dissertation in science presented to the Faculty of Medicine of the University of São Paulo in 2017: Evaluation of selective attention in patients with misophonia. There are other slightly different concepts of misophonia, but Fúlvia’s seems good for its clarity and simplicity: “misophonia is characterized by an aversion to very selective sounds, which provoke a strong emotional reaction.”
Misophony is not yet officially recognized as a disease, although there are countless cases of people who suffer far beyond being affected, that is, with prejudice. The issue is worthy of further concern and investigation. It is known that there can be varying degrees of misophony. A misophonic is plagued by specific sounds: frantic click of retractable pens, someone’s breathing, chewing, specific voice and other common or not. In most cases, the noises that torment the misophonic are related to the human body.
Scientific documentation of hearing impairment with typical city noises and even noises considered normal such as saws, alarm clocks, horns, motors and screaming is not numerous, frequent or widespread. But the subject is old. In the 1960s, the Courier review of Unesco – United Nations Educational, Scientific and Cultural Union devoted an issue to this subject.
