| 摘 要： | 本文研究了有限长充水圆柱置于水中，外声场透射形成的腔内声场自适应有源控制实验研究，结果显示，由于圆柱结构与水介质的耦合，有源控制中的声控制方法能够较好的抵消声腔主导模态和强耦合的结构主导模态，因而能够抵消在圆柱腔内较宽频带范围的声场，实验还研究了消声频带，误差传感器布放位置及肖声区域等问题。

| Abstract: | In this paper, an experimental study on adaptive active control of sound trans-mission through a finite length water-filled cylinder in underwater is carried out. It isshown that due to strong structural-cavity coupling almost all cavity-dominated modes andwell-coupled structural-dominated modes can be effectively suppressed over a wide fre-quency range. This study also involves frequency range of the primary sound to be con-trolled, arrangement of the error sensor and' sound-controlled regions', etc. |
