1. A driving sound generation device comprising:
an acquirer that acquires vehicle information on drive of a vehicle;
a storage that stores a plurality of sound source data including masker sound source data for generating a masker sound for masking a noise in the vehicle;
a first adjuster that performs a first adjustment of the plurality of sound source data in accordance with the vehicle information;
a determiner that determines whether a change amount of the vehicle information is smaller than or equal to a predetermined change amount;
a second adjuster that performs a second adjustment of at least one of the plurality of sound source data after the first adjustment other than the masker sound source data after the first adjustment, when the determiner determines that the change amount is smaller than or equal to the predetermined change amount;
a synthesizer that mixes the plurality of sound source data after the second adjustment and the masker sound according to the masker sound source data after the first adjustment to generate a pseudo driving sound to be output into a cabin of the vehicle; and
an outputter that outputs, to the cabin of the vehicle, the pseudo driving sound generated.
