2 至 8 kHz 範圍內快速心理物理調諧曲線、失真產物耳聲發射電平比函數與刺激頻率耳聲發射相位法耳蝸調諧估計的有限互換性

// Limited Interchangeability of Cochlear Tuning Estimates Across Fast Psychophysical Tuning Curve, Distortion-Product Otoacoustic-Emission Level-Ratio Function, and Stimulus-Frequency Otoacoustic Emission-Phase Methods at 2 to 8 kHz

本研究比較行為性濾波調諧曲線（fPTCs）與耳聲發射（OAE）指標在耳蝸頻率選擇性的評估｜針對67名成人在2、4、8 kHz頻率測試發現，三種方法間相關性弱且一致性差｜結果顯示個體差異明顯，尤其受聽力損失及OAE訊號品質影響，建議臨床評估時應視為互補工具而非可互換方法。

// This study examined whether behavioral (fPTCs) and otoacoustic emission (OAE)-based metrics of cochlear tuning provide interchangeable estimates of auditory frequency selectivity in individuals. Using data from 67 adults, the researchers compared tuning sharpness across three methods at 2, 4, and 8 kHz and found weak correlations and poor agreement between them. Results showed substantial individual-level discrepancies, especially related to hearing loss and OAE signal quality. The findings indicate these methods should be viewed as complementary rather than interchangeable for clinical assessments.
