1. An apparatus comprising:
an Acoustic Feedback (AFB) mitigator configured to mitigate AFB between an acoustic transducer and an acoustic sensor, the AFB mitigator comprising:
a first filter configured to generate a first filtered signal by filtering a first input signal, the first input signal based on a transducer acoustic pattern to be output by the acoustic transducer; and
a second filter configured to generate a second filtered signal by filtering the first input signal, wherein the second filter comprises an adaptive filter, which is adapted based on a difference between an AFB-mitigated signal and the second filtered signal, wherein the AFB-mitigated signal is based on a difference between a second input signal and the first filtered signal, wherein the second input signal is based on a sensor acoustic pattern sensed by the acoustic sensor.
