An objective according to one aspect of the present invention is to provide a virtual sound output device and method for outputting virtual sound for reducing a user's perception of operating noise of a suspended device. According to the present invention, the virtual sound output device comprises: a speaker which outputs sound to the interior of a vehicle; and a processor for determining whether the vehicle is in motion, and if the vehicle is determined to be in motion, for determining when an operational noise of the suspension device provided in the vehicle is generated, and for outputting a masking sound through the speaker at the time the operational noise of the suspension device is generated to reduce a driver's perception of the operational noise of the suspension device.
본 발명은 차량의 내부로 소리를 출력하는 스피커, 및 차량이 주행 중인지 여부를 판단하고, 차량이 주행 중인 것으로 판단되는 경우 차량에 구비된 현가 장치의 작동 소음이 발생하는 시점을 판단하고, 현가 장치에 의한 작동 소음에 대한 운전자의 인식률을 감소시키도록, 현가 장치의 작동 소음이 발생하는 시점에 스피커를 통해 마스킹 사운드를 출력하는 프로세서를 포함하는 것을 특징으로 한다.
