title: High-frequency audiometry above 8,000 Hz.
abstract: Human auditory sensitivity for the frequencies 8, 10, 12, 16, 18, and 20 kHz was examined in a group of 41 female university students ranging in age from 19 to 22 years. The purpose of this study was twofold: to determine the feasibility of high-frequency testing using procedures routinely employed in clinical audiometry and to collect normative data using this procedure on a young adult population. A modified Hughson Westlake procedure was employed and thresholds were obtained for both ears of each subject. It was noted that for the 20-kHz tone only 52% of the subjects tested were able to respond. Statistical analysis revealed no significant threshold differences between right or left ears for all subjects at any frequency. The approach described in the present study provided reliable thresholds and was found to be clinically feasible. Comparisons were made with similar previous studies and the results of the present study were found to be in general, overall agreement.
