Room reflections assisted spatial sound field reproduction

Abstract

With recent advances in surround sound technology, an increased interest is shown in the problem of virtual sound reproduction. However, the performance of existing surround sound systems are degraded by factors like room reverberation and listener movements. In this paper, we develop a novel approach to spatial sound reproduction in reverberant environments, where room reverberation is constructively incorporated with the direct source signals to recreate a virtual reality. We also show that the array of monopole loudspeakers required for reproduction can be clustered together in a small spatial region away from the listening area, which in turn enables the array's practical implementation via a single loudspeaker unit with multiple drivers.
