Discussion

Analysis of extended high frequency hearing thresholds in 726 adults reveals normative data, indicating variations by gender and age-related trends.

MAIN FINDING: Proposed normative data in the extended high frequency range was established for 726 participants.
KEY EVIDENCE: Males exhibited worse hearing thresholds than females, though age-related decline was similar.
APPROACH: Audiometric assessments were conducted across frequencies from 0.25 to 16 kHz, using ISO and WHO methodologies.
SIGNIFICANCE: Reliable extended high frequency norms will aid in detecting functional hearing deficits and inform future research.

Claire Dorey (2025) studied this question.
