利用失真產物耳聲發射評估人類輕度至中度傳導性聽力損失

// Estimation of minor-to-moderate conductive hearing loss with distortion-product otoacoustic emissions in humans

本研究利用脈衝失真產物耳聲發射（DPOAE）聲壓圖估算導聽性或混合性聽損患者的空氣-骨導差（ABG）｜透過刺激路徑位移與DPOAE增長曲線斜率兩項指標，成功區分導聽損與感音神經性聽損，且與實際ABG高度相關｜結果顯示DPOAE圖能準確估計ABG並與行為聽閾吻合，有助客觀診斷及追蹤耳硬化症等病變。

// This study used pulsed distortion-product otoacoustic emission (DPOAE) level maps to estimate air-bone gaps (ABG) in patients with conductive hearing loss (CHL) or mixed hearing loss. By analyzing two DPOAE metrics—the shift of stimulus path and slope of DPOAE growth functions—researchers differentiated CHL from sensorineural hearing loss (SNHL) and found strong correlations with measured ABG. The combined metrics provided accurate ABG estimates, and estimated DPOAE thresholds aligned closely with behavioral hearing thresholds. These findings suggest DPOAE level maps can objectively separate conductive and cochlear hearing loss components and support their use for diagnosing and monitoring pathologies like otosclerosis.
