一种新的利用主观听觉特性的回波抵消算法

Acoustic echo cancellation using human auditory

利用人耳的主观听觉特性,提出一种新的衡量回波抵消效果的评判标准,并以此标准为目标函数提出了一种新的基于Ba参数的回波抵消算法。实验仿真表明,新的方法相比传统方法更符合人耳听觉特性;以结合人耳听觉特性的标准衡量,新方法比传统方法在性能上有一定的提升。

This paper proposes a new evaluation standard about the performance of the acoustic echo cancellation by using human auditory. According to this evaluation standard, a new method of acoustic echo cancellation based on Ba parameter is proposed. Computer simulation shows that the new approach is more suitable for human ear and can provide performance better than traditional methods when evaluated by the standard combined with human auditory.
