1. A vehicle approach notification device comprising:

  • a position detector configured to detect a current position of a vehicle;

    a map database storing map data;

    a CPU programmed to;

    make a determination of a travel thereof in a specific area from a plurality of potential specific areas by using the current position from said position detector and the map data from said map database, andwhen information from said determination indicates the determined specific area, calculate a scale of the determined specific area by using said map data; and

    a storage storing a list of thresholds for said potential specific areas, each threshold indicating a requisite scale for emitting a notification sound of said vehicle within a corresponding one of said potential specific areas,wherein the CPU is further programmed to compare information of the calculated scale with the threshold from said storage corresponding to said determined specific area, and when said threshold is satisfied, output a control signal for emitting a notification sound of said vehicle to a notification sound control unit that controls the notification sound.
