Abstract (in Japanese) (See Japanese page) 
(in English) We are studying on perspective information of sound images given by virtual sound sources produced in front of and behind a loudspeaker array. These virtual sources were produced by focusing beam type speaker array technology. In this report, such conventional technology was modified to maintain a sufficient sound pressure level in a given listening area. More over several listening tests were performed to check how such a modification was effective to improve perceived perspective information.
