Abstract

The purpose of this analytical study is to attenuate the sound radiation from a simply supported rectangular plate excited by both the structure borne (line moment) and air borne (plane wave) excitation. The effects of minimizing the radiated sound power and of canceling the net volume velocity of the plate are compared not only in terms of the reduction in sound power but also in terms of the plate velocities. A long and narrow piezoelectric actuator is used as secondary source to actively reduce the sound radiation from the plate. Numerical simulation shows that the performance of the active control method is related to the position of the line moment and the actuator.
