摘　　要： 通过听音试验比较个性化和典型非个性化(KEMAR人工头)双耳房间脉冲响应(BRIR)在可听化质量上的差异,以探讨该差异能否被感知.首先在多媒体教室内测得6名真人受试者和一个KEMAR人工头的BRIR,并与多种声音素材卷积得到双耳试验信号.然后,采用ABX主观比较方法对由受试者本人BRIR和KEMAR人工头BRIR分别合成的双耳信号进行试听比较.试验结果表明,受试者主要通过音色辨别两者的差异,4种试验信号的平均辨别正确率达到93%.这说明,个性化与非个性化BRIR的可听化差异是可被感知的. A listening test was performed to compare the auralization quality between the individualized and the typical non-individualized （for KEMAR manikin） binaural room impulse responses （BRIRs）, with the aim of exploring whether the differences were audible. In the test, the BRIRs of six subjects and a KEMAR manikin were measured in a multimedia classroom. Then, the results were convoluted with various anechoic sound materials. Moreover, the binaural signals synthesized by the own BRIRs of the subjects were compared with those synthesized by the BRIRs of the KEMAR manikin via an ABX test. Experimental results indicate that the subjects mainly use the tone color to discriminate the signal differences, with an average discrimination rate up to 93% for the four sound materials selected for the study. It is thus concluded that the auralization differences between individualized and non- individualized BRIRs are audible.
