dc.description.abstract In this paper, we address a comparative study on Directly-Aligned Multi-Point Controlled Wavefront Synthesis (DMCWS) and Wave Field Synthesis (WFS) for realization of high-accuracy sound reproduction system, where amplitude, phase and attenuation characteristics of the wavefronts generated by DWCWS and WFS are assessed. First, in DMCWS, we can derive an optimal control line coordinate based on a numerical analysis. Next, the results of computer simulations reveal that the wavefront of DMCWS has wide availability in both spatial and frequency domains with few amplitude and phase errors, especially beyond the spatial aliasing frequency in WFS. Finally we can point out that the amplitude error of DMCWS has similar behavior to well-known spatial decay approximation expression of WFS; this implies an easiness in handling the amplitude error estimation of DMCWS. From these findings, we can conclude an advantageous position of DMCWS compared with WFS. en
