使用語音傳輸指數預測噪音與混響環境中的數字辨識測試表現

// Predicting performance on the digits-in-noise test in noise and reverberation using the speech transmission index

本研究評估噪音與混響對荷蘭語數字聽辨測試（DIN）的影響｜創新引入STI_DIN，一種調整後的語音傳輸指數，能準確預測噪音、混響及兩者合併環境下的語音識別閾值（SRT）｜STI_DIN在12秒混響時間內效果穩定，預測準確度高，多數結果與實測值誤差不超過1.7 dB，優於傳統STI指標，具實際臨床與聽力評估應用價值。

// This study evaluated the impact of noise and reverberation on Dutch digits-in-noise (DIN) test recognition and introduced the STI_DIN, an adaptation of the speech transmission index. Using both normal-hearing adults and various speech processing conditions, the STI_DIN reliably predicted speech recognition thresholds (SRT) in noisy, reverberant, and combined environments after a single noise-only SRT measurement. The STI_DIN outperformed standard STI by accurately reflecting effects up to 12-second reverberation times without significant variation across conditions. The method achieved high predictive accuracy, with most SRT predictions within 1.7 dB of measured values.
