Misophonia is a disorder characterised by intolerance, and consequent pathological reactions, to sounds that are commonly present in the environment and that do not normally elicit particular reactions in most people

As with any other psychic disorder, it is such if it significantly affects the life of the sufferer, possibly affecting social and work activities or causing some subjective suffering.

This prevents the term from being used for mild intolerances that are present in many of us, or from being used, for example, for conditions limited in time and to specific circumstances.

Certainly on the third night in a row when an alarm goes off by mistake in the shop next door, it is normal to express anger.

Equally understandable is the reaction of the call centre worker to the phone ringing as soon as he gets home after eight hours of work.
