The apparatus includes a sound playback unit including a sound comparison unit for comparing a frequency band-specific reference sound level data with an extracted plurality of frequency band-specific sound data for each frequency band in response to a comparison control signal of a control unit, a sound control unit for controlling a pitch or a volume of a plurality of frequency band-specific sample sound source data to form a plurality of frequency band-specific sample control sound source data if the extracted plurality of frequency band-specific sound data is smaller than the frequency band-specific reference sound level data, and a sound mixing unit for mixing the plurality of frequency band-specific sample control sound source data and transferring the mixed plurality of frequency band-specific sample control sound source data to the sound output unit so that a pedestrian's vehicle recognition sound can be outputted.",
