Is there an association between noise exposure and King Kopetzky Syndrome?

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. We found no relationship with noise exposure in a series of patients compared with matched controls. Here we review the evidence for and against such an influence and present fresh data in an attempt to define the role of noise, if any, in the causation of this condition. Our final conclusion is that there is no clear association between KKS and noise exposure
