    摘要: For example, an Acoustic Feedback (AFB) mitigator may mitigate AFB between at least one acoustic transducer and at least one acoustic sensor. For example, the AFB mitigator may include a first filter to generate a first filtered signal by filtering a first input signal, the first input signal nay be based on a transducer acoustic pattern to be output by the acoustic transducer; and a second filter to generate a second filtered signal by filtering the first input signal, wherein the second filter may include an adaptive filter, which may be adapted based on a difference between an AFB-mitigated signal and the second filtered signal. For example, the AFB-mitigated signal may be based on a difference between a second input signal and the first filtered signal, the second input signal based on a sensor acoustic pattern sensed by the acoustic sensor.
