长期以来,厅堂内语言清晰度的评价只能采用主观测验的方式进行,因此,受到的条件限制是很多的。而快速测试语言传输指数(RASTI)方法的提出,则使工作成为一种客观测量方法,它可在短时间内得出大厅的清晰度评分[1]。这一方法建立在调制传输函数(Modular Transfer Function简称 MTF
For a long time, the evaluation of the speech intelligibility in the auditorium can only be conducted in a subjective way. Therefore, the conditions are limited. The introduction of the Rapid Test Language Transmission Index (RASTI) approach makes work an objective measure of the hall’s sharpness score in a short period of time [1]. This method is based on the Modulation Transfer Function (MTF)
