噪声中的语音（SIN）测试包括在两个呈现水平（83和53 dB SPL）和四个信噪比（SNR）（15、10、5和0 dB）下在四个说话者的多路串音的背景中呈现的一系列电气和电子工程师协会句子。在这项研究中，九个名单进行了测试的等效性和重测信度进行了测定。20名听力正常的听众和20名倾斜感音神经性听力损失的听众作为研究对象。在每个水平的每个SNR下呈现五个句子，并且对每个句子中的五个关键词进行评分（每个呈现水平100个关键词）。每个关键词被分为正确或不正确，多个错误被分为半正确的单词。对于听力正常的听众来说，列表1、2和9以及列表3、4和5是等同的。对于两组听众来说，测试-重测相关性都很高，在0.95的置信水平下，适合句子材料的关键差异为10%至16%。由于不同列表中的下限和上限效应，许多听力正常的受试者得分不低于50%，许多听力损失的受试者得分不高于50%。建议提供替代评分，以获得50%的性能的SNR。此测试的未来版本应设计为具有改进的列表等效性和50%的性能能力。
The Speech in Noise (SIN) test consists of a series of Institute of Electrical and Electronic Engineers sentences presented in a background of four-talker babble at two presentation levels (83 and 53 dB SPL) and four signal-to-noise ratios (SNR) (15, 10, 5, and 0 dB). In this study, the nine lists were tested for equivalency and the test-retest reliability was determined. Twenty listeners with normal hearing and 20 listeners with sloping sensorineural hearing losses served as subjects. Five sentences were presented at each SNR at each level, and five key words in each sentence were scored (100 key words per presentation level). Each key word was scored as correct or incorrect, with errors of plurality scored as half-correct words. For percent-correct scores, Lists 1, 2, and 9 and Lists 3, 4, and 5 were found to be equivalent for listeners with normal hearing. For both groups of listeners, the test-retest correlations were high, and the critical differences appropriate for sentence material were 10 to 16% at a .95 level of confidence. Because of floor and ceiling effects across the different lists, many subjects with normal hearing did not score as low as the 50% level, and many subjects with hearing loss did not score as high as 50%. Suggestions are offered for alternate scoring in order to obtain a SNR for 50% performance. Future versions of this test should be designed with improved list equivalency and 50% performance capability.
