Active control of simply supported rectangular panel radiated sound

MAO Qi bo 1, JIANG Zhe 2 (1.The State Key Laboratory of Modern Acoustic,Nanjing University,Nanjing 210093,China 2.Institute of Vibration and Noise,Jiangsu University of Science and Technology,Zhenjiang 212013,China)  
In this paper, with an example of simply supported rectangular panel, it is presented active of control structure borne sound radiation by means of radiation modes. And physical characteristics and mathematical meaning of the radiation modes are analyzed. The radiation efficiency of the radiation modes falls off very rapidly with increasing modes order at low frequency. A new control strategy is developed in which by canceling the adjoint coefficient of the former k ranks radiation modes, the sound powers of the former k ranks radiation modes is zero theoretically. The numerical calculation is made by using PZT actuators as control forces. The results are compared with the traditional control strategy-the minimization of sound power.
