Abstract
Based on coupling structural–acoustic modal model, using PZT actuators and volume velocity sensor as actuator/sensor, the analytical simulations are presented for the actively controlled the sound transmission through double plate structure. Firstly, the results show the potential for using volume velocity sensors to improve sound transmission loss through double plate structures. Secondly, the effects of physical parameters of actuator/sensor and double plate structure on control performances are discussed. And some useful conclusions are obtained, for example, if volume velocity sensor is applied to radiating plate, sound transmission loss will improve significantly, no matter where the actuators (i.e. PZT actuators on incident or radiating plate) are located.
