The reliability of a closed-set Nonsense-Syllable Test was determined on a group of 38 listeners with mold-to-moderate sensorineural hearing loss. Eight randomizations of the 91-item test (four trials on each of two days) were presented monaurally, under earphones, at 90 dB SPL with a cafeteria background noise set at a +20-dB S/N ratio. Performance under these conditions ranged from 21.4 to 91.2%, reflecting the wide range of syllable-recognition ability of these subjects. Reliability of the eight measurements was determined by analysis of variance and analysis of covariance structure (parallel-test modelling) for the entire test and each of 11 subtests. Overall and individual subject results failed to show any systematic differences in scores over eight trials. Likewise, no significant differences were found in performance on individual syllables, nor were changes in the relative occurrence of specific syllable confusions noted. The test is highly reliable when evaluating hearing-impaired subjects, and thus is appropriate for use in investigations where identical items are administered under multiple experimental conditions.
对一组38名患有轻度至中度感音神经性听力损失的听力受试者进行了闭集无意义音节测试的可靠性评估。91项测试进行了8次随机排列（在两天内每天进行4次测试），通过耳机单耳呈现，声压级为90 dB SPL，同时设置了+20 dB的信噪比的自助餐厅背景噪声。在这些条件下，测试成绩从21.4%到91.2%不等，反映出这些受试者音节识别能力的广泛差异。通过对整个测试以及11个分测试中的每一个进行方差分析和协方差结构分析（平行测试建模），确定了这8次测量的可靠性。整体和个体受试者的结果均未显示出在8次测试中分数存在任何系统性差异。同样，在单个音节的表现上也未发现显著差异，特定音节混淆的相对发生率也没有变化。在评估听力受损受试者时，该测试具有高度可靠性，因此适用于在多种实验条件下给予相同项目的研究。
