N2 - Reverberation is important to perceived externalization of headphone-reproduced virtual sound sources, especially the early reflection part. The result of a previous experiment demonstrated that the degree of externalization decreased substantially by reducing the amount of reverberation at the contralateral ear. In contrast, the perceived externalization changed slightly by removing the reverberation part in the ipsilateral ear signal. In that study, a one-second-long white noise was used as the stimulus, and the simulated virtual sound source was located at a distance of 1.7 m for an azimuth angle of 45°. However, it is still unknown whether or not this effect depends on the type of stimuli and sound-source distances, and how this effect changes as a source moves from lateral to frontal incidence angles. For these purposes, non-individual binaural room impulse responses (BRIRs) were measured for different azimuth angles and distances in a listening room. The amount of reverberation was reduced in BRIRs of either the contralateral or the ipsilateral ear. Such modified BRIRs were convolved with different stimuli, and subjects rated the degree of externalization of the binaurally rendered signals presented over headphones. The results are discussed in the present study.
