單側聽損成人人工耳蝸使用者的語音辨識：預設映射程序與基於位置的映射程序比較

// Speech recognition of adult cochlear implant users with unilateral hearing loss: Default versus place-based mapping procedures

19位單側人工耳蝸成人隨機分配至預設映射或位置對應映射（將頻帶中心對應耳蝸位點）｜6個月時，位置對應組在元音辨識與噪音指向未植入耳時的遮蔽語音辨識較佳；其他單字與音素測試無差異｜結果顯示位置對應映射可在數月後改善部分語音理解，具臨床價值。

// This randomized study tested whether place-based mapping improves early speech recognition versus a default map in 19 adults with unilateral cochlear implants. Participants were assigned at activation to a default map (70–8500 Hz) or an individualized place-based map that aligned filter center frequencies to cochlear place; speech was measured at 1 and 6 months (words, phonemes, vowels in CI-alone; masked speech in bilateral listening). At 6 months the place-based group had better vowel recognition and better masked speech recognition when the masker was directed to the non-implanted ear; there were no group differences for CNC words, phonemes, or when the masker was co-located or toward the implanted ear. These preliminary results indicate place-based mapping can improve some speech outcomes after several months of CI use.
