Abstract: A sound synthesis system and method are provided for an electric or hybrid electric vehicle. The system receives an audio signal from an inverter of the vehicle comprising an analog waveform, a digital waveform, or a parameter. The audio signal from the inverter is synthesized and combined with another audio signal via at least one of combination, superimposition, mixing, multiplication, and adding, and the combined signal is amplified and output as a synthesized audio signal or as a visual display of a waveform of the amplified, combined signal.
