EN The paper explores the possible effects of reducing the amplitude of plate vibrations and of structural sound reduction through the use of piezoelectric actuators in an anti-symmetric configuration. Besides, the paper provides the levels of reduction of sound radiated by activated piezo-structural systems. Tests were run on a steel plate with 4 pairs of piezoelectric actuators, steel plate was bonded on all edges or freely supported on all edges. Plate vibrations were excited by a point force, harmonically varying in time. The calculation procedure uses the FEM approach (ANSYS).
