The aim of this work is reduction of structural noise generated by plate and its impact on plates vibrations. For this purpose a one-side clamped aluminum plate with 5 piezo elements attached is used. One of the elements is used for plate excitation, two as vibration sensors, and two as actuators. Structural noise is measured by a microphone connected with SVAN 912 E. Study was divided into three parts: measurements of vibrations and noise generated by excited plate, active vibration control, and structural noise reduction. A significant noise local noise reduction is obtained, although with increase in plate vibrations.
