// Age-Related Changes in Middle-Ear Sound Transmission: Insights From Wideband Acoustic Immittance, Distortion Product Otoacoustic Emissions, and Air-Bone Gap Analysis
本研究透過寬頻音響阻抗測量、中耳回聲反應及氣骨導差異，比較年輕與老年成人的中耳聲音傳導變化｜結果顯示老年人吸收率下降、共振頻率降低，並伴隨耳內自發回聲反應減弱｜4 kHz 頻率下吸收率與耳內回聲存在正相關，但吸收率與氣骨導差無明顯關聯｜顯示年齡影響中耳功能，對傳導性聽力損失之影響尚需進一步探討。
// This study examined age-related changes in middle-ear sound transmission using wideband acoustic immittance, otoacoustic emissions, and air-bone gap measurements in young and older adults. Older adults showed altered absorbance patterns, lower resonant frequency, and reduced otoacoustic emission responses compared to young adults. A positive association between absorbance and otoacoustic emissions was found only at 4 kHz, with no clear link between absorbance and air-bone gap. The results suggest age affects middle-ear function, but its role in conductive hearing loss remains unclear, warranting further research.
