What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Auditory sensitivity (n=162). Intervention: Extended high-frequency (EHF) audiometry. Primary outcome: Extended high-frequency thresholds and test-retest reliability.

What question did this study set out to answer?

To measure auditory thresholds above 8 kHz in older listeners and assess test-retest reliability, age and gender effects, and the influence of conventional lower-frequency hearing levels.

Implication

Supports feasibility of extended high-frequency audiometry in older adults; leaves open its clinical utility.

Key Points

To measure auditory thresholds above 8 kHz in older listeners and assess test-retest reliability, age and gender effects, and the influence of conventional lower-frequency hearing levels.
Assessed extended high-frequency thresholds (8 to 18 kHz, 0 to 110 dB SPL) in N=162 older participants (aged 60–79 years) using a commercial high-frequency audiometer.
Administered auditory tests at the start and end of a 1- to 2-hour session to evaluate test-retest reliability.
Extended high-frequency thresholds in older listeners with normal conventional hearing were substantially higher than historical controls of younger listeners, and were further elevated in older listeners with conventional-frequency hearing loss.
Thresholds at or above 8 kHz were reliably measured within a clinically acceptable ±10 dB test-retest range.
Thresholds above 8 kHz did not differ significantly between individuals aged 60–69 and 70–79 years, and gender differences diminished when controlling for conventional audiometric thresholds.

Population

162 older listeners (60-79 years)

Intervention

Measurement of extended high-frequency (EHF) thresholds using a commercially available high-frequency audiometer (8 to 18 kHz, 0 to 110 dB SPL)

Outcome

Extended high-frequency (EHF) thresholds, test-retest reliability, age and gender effects, and influence of thresholds below 8 kHzsurrogate

Extended high-frequency thresholds can be reliably measured in older adults and are substantially elevated compared to younger listeners, even when conventional hearing is normal.

Matthews et al. (1997) conducted a cross-sectional in Auditory sensitivity (n=162). Extended high-frequency (EHF) audiometry was evaluated on Extended high-frequency thresholds and test-retest reliability. Extended high-frequency audiometry thresholds above 8 kHz can be reliably measured in older adults aged 60-79 years within a clinically acceptable +/- 10 dB test-retest range.
