<p>Provided is an active silencing apparatus capable of applying a controller without consideration of crosstalk, and capable of more effectively reducing noise for occupants. Sets of speakers (21, 31) and error microphones (22, 32) are provided to the headrests (51a, 52a) of the corresponding seats (51, 52), to the parts of the seatbacks (51c, 52c) that are closer to the headrests (51a, 52a), or to the locations on the top panel (70) of the vehicle that are positioned above the seats (51, 52). Each of the speakers (21, 31) is a flat electrostatic speaker, the movable bodies of the speakers (21, 31) being formed from elastomer. Each controller (23, 33) independently performs adaptive control, controlling the speaker (21, 31) corresponding to the controller (23, 33).</p> |
