“…Estimates of reliability also are necessary to establish guidelines for determining a significant threshold shift in patients with potentially progressive hearing loss, such as those undergoing therapy with ototoxic drugs. Although there are at least two major sources of measurement error, most previous studies of the reliability of high-frequency audiometry (Beiter and Talley, 1976;Fausti et al, 1979;Fletcher, 1965;Harris and Ward, 1967;Myers and Harris, 1970) have failed to distinguish between them. First, two threshold estimates at any frequency obtained in the same session without a change in earphone placement will not agree perfectly.…”

This study compared the reliability of a recently developed high-frequency audiometer (HFA) [Stevens et al., J. Acoust. Soc. Am. 81, 470-484 (1987)] with a less complicated system that uses supraaural earphones (Koss system). The new approach permits calibration on an individual basis, making it possible to express thresholds at high frequencies in dB SPL. Data obtained from 50 normal-hearing subjects, ranging in age from 10-60 years, were used to evaluate the effects on reliability of threshold variance, earpiece/earphone fitting variance, and the variance associated with the HFA calibration process. Without earpiece/earphone replacement, the reliability of thresholds for the two systems is similar. With replacement, the HFA showed poorer reliability than the Koss system above 11 kHz, largely due to errors in estimating the calibration function. HFA reliability is greater for subjects with valid calibration functions over the entire frequency range. When average correction factors are applied to the Koss data in an effort to convert threshold estimates to dB SPL, individual transfer functions are not represented accurately. Thus the benefit of being able to express thresholds at high frequencies in dB SPL must be weighed against the additional source of variability introduced by the HFA calibration process.

The sound-pressure level thresholds in the extended high-frequency range (8 to 20 kHz) were measured in 25 non-hearing-impaired young adults from 20 to 29 years of age. The result was not unlike that obtained by previous investigators; the thresholds increased gradually as a function of frequency. However, two notable points were found: one that the threshold reached a plateau above 18 kHz, and the other that it decreased slightly at 12 kHz. As the subjects might respond to the low-frequency noise of the stimulus wave, the threshold became a plateau above 18 kHz. An acoustic resonance in the ear canal caused the threshold to decrease at 12 kHz. In clinical studies of extended high-frequency audiometry, the threshold data should be carefully evaluated above 18 kHz and at 12 kHz.
