| description | An active noise control device including: a seat control device configured to sense a seated state inside a vehicle and control a seat displacement of each seat; a microphone disposed at any one place of a ceiling inside the vehicle to receive noise from the inside and outside of the vehicle and transmit an error signal; a plurality of acceleration sensors disposed on a transfer path for a vibration transferred to the vehicle to acquire a vibration causing noise on a road surface; an active noise control module configured to receive information on a seat displacement in a seated state from the seat control device and reference signals from the plurality of acceleration sensors, set an active noise target area, and generate an active noise control sound in the set active noise target area; and a speaker configured to output the active noise control sound. |
