Abstract
This study was designed to investigate the variability in performance frequently observed when speech discrimination is assessed in the presence of background noise. Using the binomial distribution, analysis suggests variability is substantial, so speech discrimination scores obtained in noise should be interpreted with caution.
摘要
本研究旨在调查在背景噪声存在的情况下评估言语辨别能力时经常观察到的表现差异。使用二项分布进行分析表明，差异很大，因此在噪声环境中获得的言语辨别分数应谨慎解释。
