Abstract
A vehicle and an associated method for augmenting audible sound generated in a passenger compartment by operation of first and second torque machines are described. The passenger compartment includes an audio speaker that is operably controlled by a controller that is also is in communication with the first and second torque machines. The controller includes an instruction set that is executable to determine first parameters associated with audible sound generated by operation of the first torque machine and determine second parameters associated with audible sound generated by operation of the second torque machine. A desired audible sound in the passenger compartment is determined. The audio speaker is controlled to generate a correction tone based upon the first parameters, the second parameters and the desired audible sound in the passenger compartment.
