空间感主观评测中现场评测与录音评测的比较

Comparison of field evaluation and recording evaluation in subjective evaluation of spatial sense

采用声学头模进行双耳录音评测是空间感主观评测的一种方法。利用Odeon建模仿真不同空间大小中各方向的反射声,在基准电影院中形成不同空间大小的空间感,分别使用现场评测和录音评测的方法对主观空间感进行评测,并对比两种评测方法。主观实验结果显示,对录音评测结果进行一定的线性修正,可以代替现场评测。

Evaluation by binaural recording based on the acoustical dummy head, which was designed according to the aver- age physiological parameters of Chinese adults, is an effective method to evaluate on-site sound effect.Using Odeon modeling and Simulation of different spatial size of the theater＇s acoustic parameters, The experimental signal is simulated in different reference space in the benchmark movie theater.On the subjective space sense are used on site evaluation method and re- cording evaluation method, and comparing the two kinds of evaluation methods.The test result shows that the recording eval- uation results for a linear correction, instead of on site evaluation.
