In this paper the parameters of vibration control system, including placement and size of actuators was investigated. The results show that location, value, width of distribution, distribution type and phase difference between the load and actuator have a great influence on noise produced by the beams. The investigation also indicates differences in the laws of control for minimizing sound emission by simply supported and cantilever beams. The influence of actuator parameters are presented on noise cancellation and discussed.
