The invention discloses a vehicle-evocative sound generation device and method, a terminal device and a server device. A calculation part (735) receives the current position of the vehicle MV sent from the position detection part (720), calculates the distance to be traveled in the traveling direction to the intersection of the road referring to the map information in the storage part (710), and sends the calculated distance to a determination part (745). The determination part (745) determines the arrival ranges for the vehicle-evocative sounds to be outputted outside the vehicle on the basis of the calculated distance. Subsequently, on the basis of the determined arrival ranges, the control part (750) calculates the set audio volumes for the vehicle-evocative sounds to be outputted from the left and right speakers of the sound output part (760), and the vehicle-evocative sounds are outputted to the outside of the vehicle from sound output part (760) at audio volumes corresponding to the set audio volumes. As a result, the output of the sound is properly controlled, considering to the possibility that a subject to be alerted is present in the surroundings, which changes depending on the lane class of the road upon which the vehicle is traveling.
