An inverter includes paired power transistors that are electrically connected to the electric machine, wherein the inverter is electrically connected to a DC power source via a high-voltage electrical power bus. A motor controller includes a first controller and an acoustic signal generator, wherein the first controller is disposed to control the paired power transistors of the inverter. The first controller determines an initial output voltage based upon a torque command and the acoustic signal generator is disposed to generate a sound injection voltage. The motor controller combines the initial output voltage and the sound injection voltage. The motor controller generates PWM commands to control the paired power transistors of the inverter, wherein the PWM commands are determined based upon the initial output voltage and the sound injection voltage.
