    Abstract
  • This paper studied of sound radiation control from a flexible panel into a three-dimension closure using piezoelectric smart structure. In this experiment, the closure with a flexible panel was used to simulate the aircraft cabin; piezoelectric actuators and sensors were adhered to the flexible panel; as to signal treatment, this paper used VC++ to make main interface and MATLAB to do background analysis work; the signal of 100 Hz was chosed as noise source.It is pointed out that at 100 Hz, the radiate noise of closure decreases about 15 dB.The result indicates the feasibility of this treatment, and that active noise control will be an efficiency way to control radiate noise of cabins like aircraft's.
