Abstract: An engine sound cancellation method includes outputting a first artificial sound for cancelling engine noise, acquiring a mixed sound including the engine noise and a second artificial sound, in which the second artificial sound is changed from the first artificial sound according to a surrounding noise environment, acquiring the second artificial sound corresponding to the surrounding noise environment so as to significantly reduce an error in the mixed sound by learning an artificial neural network, and outputting the acquired second artificial sound as the first artificial sound.
