使用聽力保護裝置時的語音雜訊識別：人類表現與聲學預測

// Speech-in-noise recognition during hearing protector use: Human performance and acoustic prediction

本研究評估124名正常聽力者在不同噪音下佩戴多種聽力保護裝置(HPDs)對語音清晰度的影響｜大多數裝置對語音理解影響不大，唯有高阻隔耳塞表現較差，電子耳罩在詞語辨識測試中效果提升｜結合頭相關傳遞函數(空間聲音資訊)的語音清晰度指數(SII)預測更準確，顯示空間線索提升語音感知與預測可靠度。

// This study examined how different hearing protection devices (HPDs) affect speech intelligibility at various noise levels using QuickSIN and MRT tests with 124 normal-hearing subjects. Most HPDs did not degrade performance compared to open ear, except a high insertion-loss earplug, while electronic earmuffs improved results in MRT. Speech Intelligibility Index (SII) predictions were enhanced by incorporating spatial acoustic information via head-related transfer functions (sSII). The findings indicate that speech perception with most HPDs is similar to open ear and that spatial cues improve prediction accuracy.
