It is important to evaluate the effect of the number of channel signals in the sound field auralization system based on wave field synthesis. Although the effect of the number of channel signals on the physical accuracy of wave fronts was investigated, the effect of the number of channel signals on sound field perception was not evaluated. In this paper, two subjective assessments were performed for evaluating the effect of the number of channel signals on directional perception and spatial impression. The results of the two subjective assessments showed that there was no perceptual difference of the directional perception and spatial impression even if the wave fronts were reproduced in the very low frequency range.
