PROBLEM TO BE SOLVED: To perform acoustic reproduction based on the Wave Field Synthesis, even when an upper limit frequency is high and speakers are large. SOLUTION: When defining N as an integer being ≥2 and (a) as a real number which is ≤1/2 of wavelength of an upper limit frequency of a sound to be collected of ≥0 and a sound to be reproduced, N pieces of speakers 2<SB>1</SB>, 2<SB>2</SB>to 2<SB>N</SB>for reproducing sounds collected by N pieces of microphones disposed on a line at intervals (a) based on the Wave Field Synthesis are disposed while being shifted vertically in an extending direction of a line having the same shape as that of the line, to be disposed in the extending direction of the line at the intervals (a).
