Abstract
Disclosed is a sound design method for overcoming sense of difference when there is no virtual sound while an auto cruise control is activated. The method includes determining whether an accelerator pedal is actuated; upon determining that the accelerator pedal is not actuated, determining whether an auto cruise control system is operating; upon determining whether the auto cruise control system is operating, classifying a vehicle speed-based order component from a driving sound; and reproducing a speed sensitive virtual sound based on the classified vehicle speed-based order component.
