Word discrimination scores were obtained for 30 normally hearing listeners using Auditec and Rintelmann recordings of the NU-6 presented at 60 and 70 dB SPL in quiet and in a background of multitalker noise at signal-to-noise (S/N) ratios of +12, +6, 0, and -6 dB. This was done to obtain normative data and to determine whether these two recordings of the same word lists were equivalent at conversational levels in quiet and in a noisy background. The word discrimination scores for each recording in quiet and at each S/N ratio were not significantly different when presented at 60 and 70 dB SPL. However, the word discrimination scores were significantly poorer as the S/N ratio became more severe, and the scores obtained with the Auditec recording were significantly poorer than those obtained with the Rintelmann recording at each S/N ratio. These differences between word discrimination scores using the Auditec and Rintelmann recordings were primarily attributed to the recorded level of the test word and secondarily attributed to carrier phrase and talker differences.
使用Auditec和Rintelmann录制的NU - 6词表，以60和70 dB SPL的强度，在安静环境以及多说话者噪声背景下（信噪比分别为 +12、+6、0和 -6 dB），为30名听力正常的受试者获得了单词辨别分数。这样做是为了获取规范数据，并确定在安静和嘈杂背景下的对话水平中，这两个相同单词列表的录音是否等效。当以60和70 dB SPL呈现时，安静环境下以及每个信噪比下每个录音的单词辨别分数没有显著差异。然而，随着信噪比变得更差，单词辨别分数显著降低，并且在每个信噪比下，使用Auditec录音获得的分数显著低于使用Rintelmann录音获得的分数。使用Auditec和Rintelmann录音的单词辨别分数之间的这些差异主要归因于测试单词的录制水平，其次归因于载体短语和说话者的差异。
