Active control of acoustic radiation based on time radiation modes

ZHOU Xiao-nan,JIANG Zhe (Institute of Vibration and Noise,Jiangsu University,Zhenjiang 212013,China)  
A new method for the analysis on the problem of the exterior sound radiation from a rectangular baffled planar source is developed by means of the method of time domain acoustic radiation modes.Within the time domain,being time-invariant, the modes depend only on the radiator geometry.According to the fact that the sound power of the first radiation mode is the dominant for transient sound power,a control strategy in time domain is developed,in which by canceling the adjoint coefficent of the first radiation mode,the sound power of the first radiation mode is decreased effectively.And then,a simulation within the state space is done.In order to control the adjoint coefficient of the first radiation mode,an adaptive feedback control system based on optimal control algorithm is developed.In all kinds of circumferences,the sound power for the time domain sound radiation modes is estimated.Finally,the availability of the control strategy is confirmed via a software.
