【摘要】 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．更多还原

【Abstract】 In recent years,researchs for the attenuation theory of active sound control and the technique of adaptive active sound control are carried on independently. By optimizing the number and the location of error sensors,a relation between them has been found in this paper. The method and the formula for optimization are given. Factors affecting the attenuation effects are discussed. All theoretical results are verified by experiments and the attenuation effects are satisfied更多还原
