// Cortical responses to thelack of high-frequency cues in musical emotion perception
本研究探討模擬高頻與低頻聽損對音樂情緒判斷時腦部活動的影響｜腦電圖顯示，高頻聽損模擬增加α波活性，代表判斷快樂情緒及悲傷音樂喚醒度時認知負荷提升｜結果指出頻譜訊號退化會引發補償性高階認知處理，有助維持穩定的情緒評估，具實際聽覺障礙輔助應用價值。
// This study investigated how simulated high- and low-frequency hearing loss affects brain activity during musical emotion judgments. EEG recordings showed that high-frequency hearing loss simulation increased alpha-band activity, reflecting greater cognitive effort particularly in judging positive (happy) valence and arousal in sad music. Findings suggest spectral degradation triggers compensatory top-down processing to support stable emotional appraisals despite reduced auditory cues.
