1. A method comprising:
- measuring, via a sensor, an engine-related target sound for a vehicle;
that is produced by one or more vehicle components that are coupled to an engine of the vehicle;
measuring one or more vehicle parameters pertaining to operation of the engine, the vehicle parameters selected from the group consisting;
of an engine torque, engine revolutions per minute, a vehicle speed; and
a vehicle acceleration;
measuring one or more cabin sounds that entered a cabin of the vehicle from outside the vehicle as the vehicle is travelling, wherein the cabin sounds are different from the engine related target sound, and are not generated by vehicle components that are coupled to the engine;
selecting a harmonic of the engine-related target sound for manipulation, based on a comparison of the measured engine-related target sound with an expected or desired sound for a passenger in the vehicle to hear given the one or more vehicle parameters and the one or more cabin sounds, based on vehicle testing data that is stored in a memory of the vehicle, wherein the vehicle testing data reflects testing of one or more test vehicles during vehicle model development, prior to a current engine operation cycle for the vehicle, wherein the testing data includes a history of engine-related sounds that typically occur or that passengers expect or find pleasing at various values of the vehicle parameters and as blending with other sounds entering a vehicle'"'"'s cabin from outside the vehicle; and
enhancing the engine-related target sound for one or more individuals within or in proximity to the vehicle by adjusting the selected harmonic of the engine-related target sound based on the one or more vehicle parameters, the one or more cabin sounds, and the comparison of the measured engine-related target sound with the expected sound using the vehicle testing data.
