Abstract
The evaluation of high-frequency thresholds above 8 kHz has not always been accepted as a reliable, reproducible measure in routine audiological clinics. Using standard equipment we have shown that thresholds at 10 kHz and 12 kHz can be so measured, and that 16 kHz thresholds may be determined with the same degree of reliability with only the minor addition of a signal generator and a set of high performance earphones.
