An EV driving sound control system may include a sound output device of generating a driving sound of an EV vehicle; a torque measurement sensor of measuring a torque of a motor in the EV vehicle; an indoor noise measurement sensor of detecting a noise of the EV vehicle; and a signal processing controller for controlling the sound output device to reach a target tone by receiving signals from the torque measurement sensor and the indoor noise measurement sensor, wherein the signal processing controller extracts and outputs only the acceleration feeling sound component from an engine sound upon acceleration, and masks high-frequency noise upon deceleration by the sound output device, by use of the traveling information related to the EV vehicle inputted from the CAN communication in real time and the signals inputted from the indoor noise measurement sensor and the torque measurement sensor.
