System and method for steady state vehicle sound synthesis

A vehicle system comprising:

• a controller configured to:
• generate an audio signal indicative of synthesized engine noise (SEN);
• attenuate the audio signal at a first rate in response to at least one of a gear selection, an engine speed, and a pedal position indicating first vehicle conditions;
• and
• provide the attenuated audio signal to a loudspeaker mounted within a vehicle passenger compartment.

A computer-program product embodied in a non-transitory computer readable medium that is programmed for synthesizing engine noise (SEN), the computer-program product comprising instructions for:

• receiving input indicative of at least one of gear selection, engine speed, and pedal position;
• generating an audio signal indicative of SEN;
• attenuating the audio signal at a first rate in response to the input indicating first vehicle conditions;
• and
• providing the attenuated audio signal to a loudspeaker mounted within a vehicle passenger compartment.
