| Abstract: | Active Noise control is an effective way to comtrol low frequency noise.And the acoustical feedback of the secondary source is one of the key problems that affect noise reduction in ducts.In this paper,the problem is studied and a solution is put forward from the point of view of the transference function.The solution is verified by the experiment. |
