一般认为，听障人士在噪音环境下的言语测试结果不佳，不能完全以纯音听阈的提高来解释。Plomp已经表明，除其他外，还必须考虑一个额外的因素，通常统称为失真。在试图指定的听觉和认知功能，这可能是这种失真的基础上，各种研究起源于Plomp的研究小组，以及其他相关的研究提供定量数据的各种类型的听觉或认知测试（预测测试）和语音噪声测试之间的相关性。除了纯音听力图外，预测变量还包括频谱和时间分辨率、强度差阈、年龄和一些认知方面的测量。结果表明，总的来说，这些变量不足以充分解释在噪声中的语音测试中观察到的方差。这强烈表明，到目前为止考虑的预测变量不包括所有的方差相关的语音接收噪声的来源。
It is generally recognized that poor results of speech-in-noise tests by hearing-impaired persons cannot be fully explained by the elevated pure-tone hearing threshold. Plomp has shown, among others, that an additional factor has to be taken into account, often referred to in general terms as distortion. In an attempt to specify auditory and cognitive functions which may underlie this distortion, various studies on this topic originating from Plomp's research group are reviewed, as well as other relevant studies which provide quantitative data on the correlations between various types of auditory or cognitive tests (the predictor tests) and speech-in-noise tests. The predictor variables considered include, besides the pure-tone audiogram, measures of spectral and temporal resolution, intensity difference limen, age, and some cognitive aspects. The results indicate that, by and large, these variables fall short in fully explaining the variance observed in the speech-in-noise tests. This strongly suggests that the predictor variables considered so far do not cover all sources of variance relevant for speech reception in noise.
