| 摘 要： | 探讨管道中高次波的有源控制问题.首先,对消声条件下的次级声源强度进行了理论分析,并对误差传声器的数目与位置进行了讨论.最后,进行了控制方截面管中(0,0)次波(平面波)和(1,0)次波的实验.结果表明,对管道中的高次波实施有源控制是完全可能的.

| Abstract: | Active noise control of high order modes in ducts is investigated in this paper. First, the strengths of secondary source are analyzed theoritically under the condition of optimum noise attenuation, and the number and positions of error microphones are also discussed. At last, the experiments are carried out for active control of (0,0) mode and (1,0) mode in the square duct. The results have shown that it is fully possible to control high order modes in ducts by means of active method. |
