老化與聽力障礙中的周邊音素編碼與辨識

// Peripheral phoneme encoding and discrimination in aging and hearing impairment

本研究探討老化、耳蝸突觸病變與外毛細胞損傷對語音編碼及語音音素辨識的影響｜結果顯示高頻時間包絡追蹤反應隨年齡及聽力損傷減弱，低頻反應穩定｜行為測試發現基於細微結構的音素辨識隨老化及細胞流失惡化，顯示神經與行為評估結合有助早期偵測隱性聽力缺陷。

// This study investigated how aging, cochlear synaptopathy, and outer hair cell damage affect speech encoding and phoneme discrimination using EEG and behavioral tests targeting temporal envelope and fine structure cues. Results showed that high-frequency envelope-following responses decreased with age and combined hearing damage, while low-frequency envelope responses remained stable. Behaviorally, fine structure-based phoneme discrimination worsened with age and hair cell loss, but temporal envelope-based discrimination did not. The findings suggest that combining neural and behavioral measures can help detect early, hidden auditory deficits related to aging and hearing loss.
