Abstract
A virtual engine sound generating system and method are provided in which each of speakers outputting a virtual engine sound provides an intended optimal virtual engine sound to a driver by adjusting a time for a virtual engine sound to reach the driver and an amplitude of an engine sound that reaches the driver when the head position of the driver changes from a reference position. The system includes speakers provided in a vehicle to output the virtual engine sound, an engine sound generating unit generating the sound, and a controller calculating a head position of a driver based on state information of the driver's seat, adjusting a delay time at which the virtual engine sound is output and/or an amplification factor for each of the speakers based on the calculated head position, and outputting an adjusted delay time and/or amplification factor to the engine sound generating unit.
