1. An audio system comprising:
a head-mounted device worn by a user;
one or more microphones configured to capture sounds from a local area, the captured sounds including a leakage signal from the head-mounted device;
an audio controller configured to determine a mitigation signal that is out-of-phase to the leakage signal; and
a transducer array configured to provide the mitigation signal as an output signal, wherein the mitigation signal suppresses the leakage signal.
