摘要：

This paper describes the active control of sound transmission through a clamped rectangular plate by using piezoelectric ceramics as actuators and sensors. Optimal use of the piezoelectric ceramic actuator is investigated theoretically by using the transfer function from incident sound pressure to radiated sound pressure and the first order approximated damping ratio. By applying direct velocity feedback control by five pieces of the actuators, substantial reduction of peak level at eigen mode frequency is obtained below the frequency range of about 1500 Hz. The use of piezoelectric ceramics as actuators and as sensors fails in the direct velocity feedback control experiment, but has potential for the direct position feedback control experiment.
