摘要
本文介绍三部分内容:1.测量的汉语普通话MTF特性;2.利用汉语可懂度的实验结果,根据实验室内不同信噪比条件下的数据得出汉语普通话音节清晰度和STI的关系曲线,比较了汉语STI值和RASTI值的相关性;3.在海淀影剧院直接用B&K公司RASTI测量仪器进行测量。
In this paper, an introduction to the three contents is given as follows: (1) Measurement of MTF characteristics of Chinese Standard. (2) By using the experimental results of the intelligibility of Chinese and the data at different S/N conditions in laboratory,the relation between the syllable articulation and ST1 can be obtained. Finally the correlation between STI and RASTI of Chinese has been compared. (3) In the HAI-DIAN Cinema, measurement can be carried out by using the B&K RASTI measuring instruments. So as to observe the rationality of RASTI in the auditorium.
