Abstract (in Japanese) (See Japanese page) 
(in English) Transaural reproduction using a few loudspeakers and cross-talk canceller (CTC) is one approach to reproduce binaural signals at listener’s both ears. Transaural reproduction system enables a presentation of binaural signals without any contact to a listener’s head or pinnae, which is a remarkable advantage over headphone reproduction. However, CTC utilized in transaural reproduction is sensitive to, therefore not robust against, a listener’s head movement that has been shown to play an essential role in sound image localization and auditory spatial perception, thereby restricting a listener’s head movement. This motivated us to develop a dynamic transaural reproduction system that updates the CTC filters in response to the listener’s head movement using non-contact head tracking based on a depth image sensor. Sound localization experiments using the developed dynamic transaural reproduction system indicated that source direction was perceived more accurately in head move condition than head still condition, which indicates the developed system works effectively; source distance, however, was perceived more accurately in head still condition; very little in-head localization was observed in both conditions.
