電耳蝸植入使用者ECAP振幅增長函數與知覺增長之關係：對個別化電耳蝸植入調適的啟示

// Relationships between ECAP amplitude growth functions and perceptual growth in cochlear implant users: Implications for individualized cochlear implant fitting

本研究探討電生理複合動作電位（ECAP）振幅增長函數與人工耳蝸使用者的響度增長關係｜分析16位使用者不同刺激速率下的數據，建立指數模型成功預測響度變化，66%的資料擬合度高於R²=0.8｜結果顯示響度增長受刺激速率影響，證實ECAP可客觀估計響度，有助個人化人工耳蝸調整。

// This study investigated whether the electrically evoked compound action potential (ECAP) amplitude growth function (AGF) can predict loudness growth in cochlear implant users. Using ECAP and psychophysical loudness data from 16 users at various stimulation rates, a power-law model was fitted to relate ECAP amplitude to perceived loudness. Results showed loudness growth depends on stimulation rate, with the model accurately predicting loudness (66% of fits R²>0.8). This demonstrates ECAP AGFs can objectively estimate loudness growth, aiding personalized cochlear implant fittings.
