The present invention provides a method for generating a pedestrian protection sound using multiple sound sources which uses a fade-in or a fade-out function for multiple sound sources to correct a volume in a section where the multiple sound sources overlap to generate the volume to 100% to prevent sound source disconnection which occurs when generating the multiple sound sources. According to an embodiment of the present invention, the method for generating a pedestrian protection sound using multiple sound sources comprises: a step of generating a first sound source having a frequency according to a first speed of a vehicle; and a step of changing the first sound source to a second sound source having a frequency according to a second speed of the vehicle. The second speed comprises a speed A-B section, a speed A section, and a speed A+B section, and a volume is corrected according to each section of the second speed. |
