本文对SPCA重建的HRTF的主观评价进行了研究。结果发现，与Takane在他的论文[8]中讨论的那些相比，用更少数量的PC可以重建与原始HRTF主观上听不见的差异。这使得HRTF的空间变化可以被更复杂地表示出来。通过3AFC听力实验发现，C和L领域的正确答案数显著偏多的条件数相对较少。特别是，当领域C中的PC数量为6时，没有受试者具有显著大的正确答案数量。
In this paper, the subjective evaluation of the HRTFs reconstructed with the SPCA were mentioned. As a result, it was found that the reconstruction of the HRTFs with subjectively inaudible difference from the original ones are possible with smaller number of PCs than those Takane dicussed in his paper[8]. This brings about a expection that the spatial variation of HRTFs can be represented more compactly. Throught the 3AFC hearing experiment, it is found that the domain C and L have the relatively small number of conditions with significantly large number of correct answers. Especially, there were no subjects having significantly large number of correct answers when the number of PCs is 6 in the domain C.
