NOTIFICATION DEVICE

A notification device includes an object detection unit configured to detect a position and a relative condition of an object around a host vehicle; a virtual sound source setting unit configured to set a virtual sound source around the driver, based on the detected position of the object; a sound output unit configured to output a notification sound to a driver; and a sound output control unit configured to output the notification sound from the sound output unit such that the driver identifies that the notification sound in response to the relative condition has come from a direction of the set virtual sound source, based on the set virtual sound source and the relative condition.
