Multi-mode noise reduction of using piezoelectric shunt damping smart panels

In this paper, the transmitted noise reduction of smart panels of which passive piezoelectric shunt damping is used, is experimentally studied. Shunt damping experiments are based on the measured electrical impedance model. A passive shunt circuit composed of inductor, and load resistor is devised to dissipate the maximum energy into the joule heat energy For multi mode shunt damping, the shunt circuit is redesigned by adding a blocking circuit.
