Embodiments are disclosed for generating masking sounds in a vehicle, such as an at least partially electric vehicle. An example sound generation system in a vehicle includes a speaker, a processor, and a storage device holding instructions executable by the processor to modulate a sound characteristic of a first frequency range of a synthetic sound to generate a modulated synthetic sound portion while maintaining the sound characteristic of a second frequency range of the synthetic sound that is lower than the first frequency range to generate an unmodulated synthetic sound portion. The instructions are further executable to output a combined synthetic sound including both the modulated synthetic sound portion and the unmodulated synthetic sound portion. The sound characteristic of the first frequency range may be modulated as a function of a vehicle operating parameter.
