語音品質對正常聽力及聽力損失成人可接受噪音水準的影響：引入訊號退化程度指標

// Voice quality influences acceptable noise levels in adults with normal hearing and hearing loss: introducing the signal degradation degree

本研究探討說話者語音品質對可接受噪音水準（ANL）的影響｜發展訊號劣化程度（SDD）衡量個體對語音變化的敏感度｜結果顯示語音品質降低時，ANL提升，噪音容忍度下降，且正常聽力者對語音劣化更敏感｜SDD有助量化此效應，未來仍需驗證臨床應用價值。

// This study investigated how speaker voice quality affects acceptable noise level (ANL) and introduced Signal Degradation Degree (SDD) to measure individual sensitivity to voice-related signal changes. Participants with normal hearing and hearing loss listened to speech with varying voice qualities, and ANL increased as voice quality worsened, showing reduced noise tolerance. Normal hearing adults showed greater sensitivity to voice quality degradation than those with hearing loss. The findings suggest voice quality impacts noise tolerance, and SDD may help quantify this effect, though further validation is needed for clinical use.
