Sub-Band Adaptive Acoustic Echo Cancellation Using Human Auditory Feature

The using of human auditory feature in acoustic echo cancellation (AEC) is discussed in this paper. Firstly, the AEC based on sub-band is introduced. After that, the auditory equal-loudness and masking effect are introduced. At the same time, two kind of AEC algorithm is proposed, the first is sub-band AEC using auditory equal-loudness feature and the second one is the sub-band stereo AEC using auditory masking effect. Final experiments indicate that both of these two algorithms achieve better performance than traditional AEC algorithm.
