透過調整非個人化頭部相關房間響應的音量與反射強化雙耳合成中額葉虛擬聲源的外部化

// Enhancing Externalization of Frontal Virtual Sound Sources in Binaural Synthesis via Level and Reflection Adjustment of Non-individualized BRIRs

本研究針對單一喇叭非個人化雙耳房間脈衝響應(NI-BRIRs)改善前方虛擬聲源（0°-30°方位）的外放感｜採用兩階段方法調整雙耳聲壓與強化早期反射以優化直射與反射聲比｜實驗證實此方法顯著提升空間聲音的真實感，具備提升穿戴式音訊裝置空間感知的實際應用價值。

// This study improves externalization of frontal virtual sound sources (0°-30° azimuth) in binaural synthesis using single-speaker non-individualized binaural room impulse responses (NI-BRIRs). A two-phase method was developed: first, scaling binaural levels to equalize levels across azimuths; second, enhancing early reflections to adjust the direct-to-reflection sound ratio. Both phases significantly improved perceived externalization. The approach offers a practical correction for wearable audio devices, enhancing realistic spatial sound perception.
