Abstract:
A reproduction apparatus that realizes reproduction of which sound leakage is small with use of a speaker installed near a head, and a method and a program thereof are provided. The reproduction apparatus is used in a seat. The reproduction apparatus includes: at least two speakers; an acquisition unit that acquires, from a predetermined sound source, an acoustic signal of which sound is emitted by the reproduction apparatus; and a control unit that controls the acoustic signal acquired by the acquisition unit such that reproduction sound is only transmitted to a first seat and the reproduction sound is not transmitted to a second seat, the speakers each emit sound of the acoustic signal controlled by the control unit, and the speakers are disposed so as to be closer to an ear of a user that sits in the first seat than to the second seat.
