Noise suppression in curved glass shells using macro-fiber-composite actuators studied by the means of digital holography and acoustic measurements
Original language description
The paper presents methods and experimental results of the semi-active control of noise transmission in a curved glass shell with attached piezoelectric macro fiber composite (MFC) actuators.The semi-active noise control is achieved via active elasticitycontrol of piezoelectric actuators by connecting them to an active electric shunt circuit that has a negative effective capacitance.Using this approach, it is possible to suppress the vibration of the glass shell in the normal direction with respect toits surface and to increase the acoustic transmission loss of the piezoelectric MFC-glass composite structure. The effect of the MFC actuators connected to the negative capacitance shunt circuit on the surface distribution of the normal vibration amplitude is studied using frequency-shifted digital holography (FSDH).The principle of the used FSDH method is described in the paper. The frequency dependence of the acoustic transmission loss through the piezoelectric MFC-glass composite
