Abstract
Attenuation of output levels is suppressed while interference due to a plurality of vibrators is reduced. An acoustic control deviceperforms correction processing of correcting phase delay characteristics including transmission systems from excitersL andR which are first and second vibrators connected with a rigid body, on acoustic signals SR and SL. Thereafter, the acoustic control devicecontrols the excitersL andR on the basis of the corrected acoustic signals SLand SR
