Abstract
Sound can be listened to only in a listening area by maximizing a sound energy difference between a listening area and a non-listening area while maximizing sound radiation efficiency of each sound source. Accordingly, realistic sound can be provided to listeners without causing auditory disturbance to third parties, and maximal sound effects can be obtained with only minimal control.
