摘要：
Attenuation of output levels is suppressed while interference due to a plurality of vibrators is reduced.
An acoustic control device 30 performs correction processing of correcting phase delay characteristics including transmission systems from exciters 21L and 21R which are first and second vibrators connected with a rigid body, on acoustic signals SR and SL. Thereafter, the acoustic control device 30 controls the exciters 21L and 21R on the basis of the corrected acoustic signals SL1 and SR1.
