言语接收阈值（SRT）的句子，确定在平稳和调制的背景噪声为两个年龄匹配组的正常听力（N=13）和听力受损的听众（N=21）。研究噪声中SRT与听觉和非听觉性能指标之间的相关性，然后分别在两组内进行逐步回归分析。听力测量包括纯音听力图以及频谱和时间敏锐度测试。非听觉因素进行了评估，通过测量文本接收阈值（TRT），视觉模拟的SRT，其中部分掩蔽的句子自适应地提出。结果表明，对于正常听力组，语音接收的方差主要与非听觉因素有关，无论是在平稳噪声还是在调制噪声中。对于听力受损的群体，在平稳噪声中的言语接收主要与听力图有关，即使考虑到可听度效应。在调制噪声中，听觉（时间敏锐度）和非听觉因素（TRT）有助于解释言语接收的个体间差异。年龄不是影响结果的重要因素。得出结论，在一定条件下，非听觉因素是相关的噪声中的语音感知。非听觉因素的进一步评估可能使适应的期望，在临床环境中的听觉康复。(c)2007年，美国声学学会。
Speech reception thresholds (SRTs) for sentences were determined in stationary and modulated background noise for two age-matched groups of normal-hearing (N=13) and hearing-impaired listeners (N=21). Correlations were studied between the SRT in noise and measures of auditory and nonauditory performance, after which stepwise regression analyses were performed within both groups separately. Auditory measures included the pure-tone audiogram and tests of spectral and temporal acuity. Nonauditory factors were assessed by measuring the text reception threshold (TRT), a visual analogue of the SRT, in which partially masked sentences were adaptively presented. Results indicate that, for the normal-hearing group, the variance in speech reception is mainly associated with nonauditory factors, both in stationary and in modulated noise. For the hearing-impaired group, speech reception in stationary noise is mainly related to the audiogram, even when audibility effects are accounted for. In modulated noise, both auditory (temporal acuity) and nonauditory factors (TRT) contribute to explaining interindividual differences in speech reception. Age was not a significant factor in the results. It is concluded that, under some conditions, nonauditory factors are relevant for the perception of speech in noise. Further evaluation of nonauditory factors might enable adapting the expectations from auditory rehabilitation in clinical settings. (c) 2007 Acoustical Society of America.
