ABSTRACT: Noise and vibration control of plates using active elements is presented here as a result of experimental work. The objective of this work is to study the possibility of controlling the noise and vibration of plates using a simple control regime. Active reduction of plate′s noise and vibration is evaluated for a test steel plate excited using a B&K exciter. Smart damping materials (piezo-ceramics) are used for accomplishing the process of reducing the plate vibration and born noise. The system is built up with an analogue to digital converter fed with the measured vibration signal after passing through a low –pass filter. The output is manipulated through a computer to produce an analogue signal using a digital to analogue converter, which is fed to the piezo-ceramic actuator without any frequency modifications. The actuator vibrates in response, to counter act and to damp the structure vibration. The test results show that the vibration peaks at multiple frequencies are reduced. It also shows that the structural borne noise is substantially reduced using smart damping materials, indicating the validity of its usage for industrial applications to reduce noise and vibration.
