Repeatability of high-frequency thresholds.
High-frequency (10, 12, 14, 16, and 18 kHz) thresholds were obtained for each ear of 50 young adults having normal low-frequency hearing across four test sessions separated by at least 1, but no more than 2, weeks using a Beltone 2000 audiometer. The threshold differences between each possible test session comparison (N = 6) were not significantly (p greater than 0.05) different for ear, test session comparison, or frequency. Overall, intrasubject high-frequency thresholds were found to be repeatable and within a clinically acceptable range of +/- 10 dB for at least 94% of the ears, regardless of test session comparison and frequency.
