ヘッドホンを用いたバイノーラル再生における個人性補正の効果(<特集>音)

抄録

When sounds are recorded with microphones placed at the ears ofa dummy head to be reproduced to the ears of a listener with headphones, correct binauralreproduction cannot be made because the acoustical characteristics of the outer ears are convoluted redundantly. To overcome this problem, calibration using a dummy head is usually conducted. This calibration is not enough since individual differences in the acoustical characteristics of listeners are ignored. In this paper, individual calibration in which calibration is applied considering the acoustic characteristics of the actual listener is proposed. Experimental results show that the effect of the individual calibration is significantly better than the usual method.binaural reproduction
