To define extended high-frequency hearing threshold ranges in normal hearing elderly (aged 55 years and above) and identify associated risk factors for extended high-frequency hearing loss.
Pure-tone thresholds (0.25–16 kHz) and word recognition scores were measured using portable audiometric equipment. Lifestyle and medical histories were collected, and generalised linear models analysed risk factors for extended high-frequency hearing (10–12 kHz).
In normal hearing elderly (28 ears, 18 subjects), 95 per cent confidence intervals for 10 and 12 kHz were 34.770–49.301 and 56.976–65.809, respectively. Among 342 ears (200 subjects), hypertension emerged as a leading risk factor for extended high-frequency hearing loss, while lipid-lowering medications showed potential protective effects.
Preliminary extended high-frequency hearing thresholds were established, with hypertension identified as a key risk factor and lipid-lowering medications as a potential protective factor.
