Abstract: PURPOSE: An active noise control device for a vehicle and a method thereof are provided to install a microphone for measuring noise and a speaker for a noise reduction in a special seat inside a vehicle and to process noise signals by dividing into low frequency noise and high frequency noise so that a noise control is possible around the special seat in the vehicle. CONSTITUTION: An active noise control device for a vehicle comprises a reference acoustic pressure setting member(10), a noise measuring member(20), a reference frequency detecting member(30), a control member(40), a low frequency noise reduction member(50), and a high frequency noise reduction member(60). The reference frequency detecting member detects a specific frequency of noise signals generated in an engine of a vehicle as a reference frequency. The control member extracts the noise signals corresponding to the reference frequency detected by the reference frequency detecting member from noise signals measured by the noise measuring member and generates noise reduction signals for low frequency noise signals having a reference acoustic pressure and noise reduction signals for high frequency noise signals after dividing the extracted noise signals into the low frequency noise signals and high frequency noise signals. The low frequency noise reduction member reduces low frequency noise by outputting first noise reduction signals from the control member. The high frequency noise reduction member reduces high frequency noise by outputting second noise reduction signals from the control member.
