ABSTRACT:
A sound output system has a pair of right and left speakers and a pair of audio mirrors for respectively controlling directivities of sounds which are output from the pair of speakers. The shapes or arrangement of the pair of audio mirrors are adjusted such that a difference between arrival times of the sounds which are respectively output from the pair of speakers can be compensated by a sound pressure difference due to the Haas effect in a predetermined area. Alternative means are phase difference, dipole, and asymmetrical horn loading.
