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

Figure 3

Comparison between (a) in-cylinder static pressure and (b) acoustic pressure for a single-cylinder diesel engine. For the acoustic pressure, the gray and black lines show measured and filtered (from 1.1 to 2.9 kHz and 1.9 to 2.1 kHz) acoustic pressures to minimize influence from the dynamometer used in the experiments.
