6. A method to simulate a noise environment of a vehicle, the method comprising:
generating, by a control unit, a reference signal based on a pre-stored reference sample signal;
generating, by the control unit, a noise signal based on a pre-stored noise sample signal;
transmitting, by the control unit, the reference signal to a noise control system;
outputting, by a speaker, a sound wave converted from the noise signal;
receiving, by the control unit, time information from a noise control system, wherein the time information includes a reception time at which the noise control system receives the reference signal and a measurement time at which the noise control system measures the noise signal; and
adjusting, by the control unit, at least one of a transmission time of a next reference signal or an output time of a next noise signal based on both the reception time of the reference signal and the measurement time of the noise signal.
