The condition in which individuals with normal pure tone audiograms complain of hearing difficulties, especially in the presence of background noise, (normal pure tone audiograms), has had a number of different names. The present term King-Kopetzky Syndrome was coined by Hinchcliffe in 1992. This is a common condition reported in 5 - 10% of those attending clinics complaining of hearing problems. A dominant genetic aetiology has been found in a proportion of cases. It may be associated with minor peripheral or central auditory dysfunction, and frequently the individuals exhibit anxious or depressive personalities.
