A vehicle sound generation device includes a sound control circuit that sets one or more frequencies according to a number of revolutions of the rotary power source, and generates a synthetic sound signal representing a synthetic sound including one or more element sounds having the one or more frequencies. The sound control circuit sets the synthetic sound so that a sound pressure of the synthetic sound includes a reference sound pressure component and a variable sound pressure component. A magnitude of the reference sound pressure component increases as the number of revolutions of the rotary power source increases, and a magnitude of the variable sound pressure component varies within a predetermined amplitude with a period of a predetermined increase amount of the number of revolutions as the number of revolutions of the rotary power source increases.
