Abstract (in Japanese) (See Japanese page) 
(in English) Authors proposed a method for acquisition of Head-Related Transfer Functions (HRTFs) or Head-Related Impulse Responses (HRIRs) from the impulse reponse measured in ordinary sound field with reflection and noise based on Linear Prediction (LP) of the impulse response with its reflection component cut out [Takane et al., Proc. JCA(2007)]. In this report, the results of the experiment, aiming at detecting any audible difference between the stimulus generated by using the estimated HRIRs and that by the measured HRIRs, was mentioned. Moreover, the relation of the subjective difference to the objective difference such as SDR (Signal-to-Deviation Ratio) and absolute level difference was investigated. Any audible difference seems not to be significantly detected when the estimated HRIR has the SDR of more than about 20 dB.
