Abstract

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.
