In this study, the Audioscan test has been used to detect early signs of hearing 
abnormalities in 80 patients with King-Kopetzky syndrome. A significantly higher 
prevalence of Audioscan notches between 500 and 3,000 Hz was found for each age 
band and gender in patients with King-Kopetzky syndrome than in control 
subjects. This indicates that Audioscan notches between 500 and 3,000 Hz may 
represent a fine hearing deficit as an indicator of mild auditory dysfunction in 
patients with King-Kopetzky syndrome. However, there was no significant 
difference in the percentage of notches in the 3,001-8,000 Hz frequency band 
between the King-Kopetzky syndrome and control groups.
