Artificial Engine Sound Synthesis Method for Modification of the Acoustic Characteristics of Electric Vehicles

<div>Spectral characteristics of (a) gasoline and (b) diesel engine sounds measured in the laboratory. The spectrum showed a decreasing level with increasing frequency, and the combustion noise at high frequencies over 1 kHz was larger for the diesel engine.</div>
