Misophonia (or selective sound sensitivity syndrome) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues. These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses not seen in most other people. [ 8 ]
Hyposensitivity, also known as Sensory under-responsitivity, refers to abnormally decreased sensitivity to sensory input.
