The invention provides an analog sound generating device and an analog sound generating method. According to the current position of a vehicle (CR), a control unit (110) is used for determining whether opposite running lanes exist on a road where the vehicle (CR) is running or not by reference to the information indicating whether the opposite running lanes exist or not in map information (MPD) stored in a storage unit (120). The control unit (110) is used for determining a reaching range of an analog sound output out of the vehicle according to the determined existence or inexistence of the opposite running lanes. Next, the control unit (110) is used for determining set volume of the analog sounds output from a left speaker and a right speaker of an analog sound generating unit (130) according to the determined reaching range. As a result, analog sounds with volume corresponding to the set volume are output out of the vehicle from the left speaker and the right speaker of the analog sound generating unit (130). Therefore, the volume of the analog sounds can be appropriately controlled while the probability that a report object exists in the surroundings, which is changed according to the situation that whether the opposite running lanes exist on the running road, is taken into consideration.
