Claim 23:
24. A product comprising one or more tangible computer-readable non-transitory storage media comprising instructions operable to, when executed by at least one processor, cause an Acoustic Feedback (AFB) mitigator to mitigate AFB between an acoustic transducer and an acoustic sensor, wherein the instructions, when executed, cause the AFB mitigator to:
generate by a first filter 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
generate by a second filter 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.
