本文介绍了噪声中语音（SIN（TM））测试（Etymotic Research，1993）的缩短和改进版本。在四个实验中的前两个中，一个女性说话者的水平相对于四个说话者的水平被逐句调整，以产生正常听力受试者50%的正确分数。在后两个实验中，那些产生缺乏等效性或高跨学科差异的分数的胡言乱语被丢弃。这些实验产生了12个等效列表，每个列表包含六个句子，每个句子在25，20，15，10，5和0 dB的每个调整后的信噪比下。另外六个列表也是等同的，当特定对的分数被平均时。最后的列表包括“QuickSIN”测试，该测试测量收听者在多路重合的背景下理解句子中50%的关键词所需的SNR。基于重测数据，听力受损受试者的单列表分数的标准差为1.4 dB SNR。一个QuickSIN列表大约需要一分钟的时间来管理，并在95%的置信水平下提供精确到+/- 2.7 dB的SNR损失估计。(C)d 2004年，美国声学学会。
This paper describes a shortened and improved version of the Speech in Noise (SIN(TM)) Test (Etymotic Research, 1993). In the first two of four experiments, the level of a female talker relative to that of four-talker babble was adjusted sentence by sentence to produce 50% correct scores for normal-hearing subjects. In the second two experiments, those sentences-in-babble that produced either lack of equivalence or high across-subject variability in scores were discarded. These experiments produced 12 equivalent lists, each containing six sentences, with one sentence at each adjusted signal-to-noise ratio of 25, 20, 15, 10, 5, and 0 dB. Six additional lists were also made equivalent when the scores of particular pairs were averaged. The final lists comprise the "QuickSIN'" test that measures the SNR a listener requires to understand 50% of key words in sentences in a background of babble. The standard deviation of single-list scores is 1.4 dB SNR for hearing-impaired subjects, based on test-retest data. A single QuickSIN list takes approximately one minute to administer and provides an estimate of SNR loss accurate to +/- 2.7 dB at the 95% confidence level. (C)d 2004 Acoustical Society of America.
