1. A method of noise mitigation for an active suspension system of a vehicle, the method comprising:
(a) obtaining, via one or more sensors on the vehicle, noise data or vibration data;
(b) obtaining operating parameters of a hydraulic motor-pump of the active suspension system;
(c) determining, based on the operating parameters of the hydraulic motor-pump and at least one of the noise data or vibration data, a noise-cancelling audible sound to be provided by a speaker; and
(d) operating the speaker to produce the noise-cancelling audible sound.
