近年来对有源消声理论以及自适应有源消声技术的研究一直是相互独立着进行的，本文通过对自适应有源消声系统中误差传声器个数以及位置的优化选择，找到了它们两者之间的联系，并结合控制系统的性能特点给出了误差传声器个数及位置优化的方法，对影响自适应有源消声效果的因素做了分析讨论，实验验证了本文所得结论，并取得了良好的效果．
In recent years, the research of active muffling theory and adaptive active muffling technology has been carried out independently of each other. In this paper, we find the optimal selection of the number and position of error microphones in adaptive active muffler system The relationship between the two and the performance characteristics of the control system is given error the number of microphones and location optimization method, the factors that affect the adaptive active muffler effect were analyzed and discussed, the experimental results verify the conclusions obtained in this paper, And achieved good results.
