Abstract
A sound synthesis system is provided with a loudspeaker to project sound indicative of synthesized motor sound in response to receiving a synthesized sound (SS) signal, and a processor. The processor is programmed to: estimate motor sound based on a sensor signal indicative of sound present within a passenger compartment; identify a dominant motor harmonic of the motor sound with an amplitude and a frequency; determine an enrichment value of the motor sound; determine if the motor sound is unenriched based on a comparison of the enrichment value to an enrichment threshold value; generate at least one additional motor harmonic with a first frequency that is different than the frequency of the dominant motor harmonic in response to the motor sound being unenriched; and provide the SS signal to the loudspeaker, wherein the SS signal is indicative of the at least one additional motor harmonic.
