具有及未具內耳畸形之人工耳蝸使用者語音可懂度與頻譜解析度結果及插入角深度影響

// Speech Intelligibility and Spectral Resolution Results in Cochlear Implant Users With and Without Inner Ear Malformations and the Effect of Angular Insertion Depth

本研究比較正常耳蝸與內耳畸形（IEM）之兒童人工耳蝸使用者的噪音中語音感知與頻譜解析能力｜結果顯示IEM組需更高訊噪比且頻譜解析較差｜電極插入深度越深與語音感知及頻譜解析正相關，但插入深度獨立影響有限｜凸顯耳蝸結構及電極位置對聽覺成效的重要性。

// This study compared speech perception in noise and spectral resolution between pediatric cochlear implant users with normal cochleae and those with inner ear malformations (IEMs). Using speech-in-noise tests and spectral ripple tests, the study found that IEM users performed worse, requiring higher signal-to-noise ratios and showing reduced spectral resolution. Deeper electrode insertion depth (AID) correlated with better speech perception and spectral resolution, but its independent effect on spectral resolution was limited after accounting for other factors. The findings highlight the influence of cochlear anatomy and electrode placement on auditory outcomes in pediatric CI users.
