The interlist equivalency of the CID W-22 word lists administered in quiet and in a background of noise was investigated using 48 normal-hearing subjects. All four word lists were administered at 20 dB SL in quiet and in the presence of a multitalker babble (0 dB signal-to-noise ratio). In the statistical analyses, word performance and subject performance were used as the dependent measures. The results indicated that: (1) the lists are equivalent when administered in quiet; (2) the lists are not equivalent when administered in a background of multitalker babble; (3) the addition of noise changes the relationship among the word lists in a nonpredictive manner; and (4) the addition of noise changes the level of difficulty of some words of each list to a greater degree, relative to the other words. The results are discussed relative to their implications for hearing evaluation and hearing aid evaluation procedures.
使用48名听力正常的受试者，研究了在安静环境和噪声背景下施测的CID W - 22单词表的列表间等效性。所有四个单词表均在安静环境中以及在多说话者嘈杂声（信噪比为0 dB）的情况下以20 dB SL进行施测。在统计分析中，单词表现和受试者表现被用作因变量指标。结果表明：（1）在安静环境中施测时，这些列表是等效的；（2）在多说话者嘈杂声背景下施测时，这些列表不等效；（3）添加噪声以一种不可预测的方式改变了单词表之间的关系；（4）添加噪声相对于其他单词，在更大程度上改变了每个列表中某些单词的难度水平。针对这些结果对听力评估和助听器评估程序的影响进行了讨论。
