Disentangling the Contributions of Extended High-Frequency Thresholds and Chronological Age to TEOAE Amplitudes: A Hierarchical Regression Analysis
Objective: Extended high-frequency (EHF) audiometry (9–20 kHz) is increasingly recognized as a sensitive tool for detecting early cochlear damage. However, the extent to which EHF sensitivity influences cochlear active mechanisms in the lower frequencies, measured by transient evoked otoacoustic emission (TEOAEs), rema...
