In this paper a virtual sound source reproduction method is proposed using two circular loudspeaker arrays with rigid baffles. This study aims to reproduce virtual sources in front of, or outside the loudspeaker arrays, with each array considered as an infinite-length rigid cylinder with loudspeakers attached to its surface. Transfer functions that consider the reflection between the two arrays are introduced, and the appropriate reflection times to be used in the transfer function are discussed. Using the pressure-matching method and circular harmonic expansion, several methods are proposed and compared via computer simulation
