Description	This paper analyzes the possibility of suppression the sound transmitted through glass windows using piezoelectric actuators shunted by an active electronic circuit. We propose a simple way to increase the bending stiffness of the glass plate which results in an increase in reflected acoustic pressure and in a decrease in transmitted acoustic pressure. The method uses Piezoelectric Macro Fiber Composite (MFC) actuators which are distributed on the glass surface. They are shunted by active electronic circuits with a Negative Capacitance (NC) which control the effective elastic parameters of the piezoelectric material. Thus, the actuators are effectively stiffened and the effective bending stiffness of the whole system could be increased. The sound shielding efficiency of the glass plate is measured by the acoustic Transmission Loss (TL). The effect of the shunted NC circuit and glass plate geometry on the TL is analyzed using Finite Element Method (FEM). Results show that it is possible to increase the TL by about 25 dB at both first vibrational mode due to the curved geometry and at the second vibrational mode due to the effect of properly adjusted shunted NC circuit.
