Residual feedback suppression with extended model-based postfilters
2021
EURASIP Journal on Audio, Speech, and Music Processing
AbstractWhen designing closed-loop electro-acoustic systems, which can commonly be found in hearing aids or public address systems, the most challenging task is canceling and/or suppressing the feedback caused by the acoustic coupling of the transducers of such systems. In many applications, feedback cancelation based on adaptive filters is used for this purpose. However, due to computational complexity such a feedback canceler is often limited in the length of the filter's impulse response.
