Apparatus, system, and method of Acoustic Feedback (AFB) mitigation

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...

Zusammenfassung: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.
