Methods and systems are provided for adaptive pulse width modulated control of an electrified powertrain of a vehicle. In one example, a method may include perturbing a switching frequency for pulse width modulated control of the electrified powertrain, and, responsive to sound measured in a vehicle cabin indicating a noise improvement after the perturbation, controlling the electrified powertrain with the perturbed switching frequency. In this way, acoustic emissions from an electrified powertrain may be reduced.
