摘要
为了使用客观指标评价与预测室内汉语言清晰度,通过室内汉语言清晰度主观评价实验,探讨了客观指标有益有害声能比U50与汉语言清晰度之间的相关关系,并得到两者之间的回归预测方程。研究表明汉语言清晰度SI与客观指标U50之间有着很强的相关关系,可以使用U50有效地评价汉语言清晰度。
For employing objective parameters to assess and predict Chinese speech intelligibility, the correlation between Chinese speech intelligibility and useful/detrimental ratio U50 is studied by subjective tests. Their regression equation is also obtained. It shows that the Chinese speech intelligibility is highly correlated with the objective parameter U50 that it could be evaluated by U50 effectively.
