The effect of random parametric noises on reduction of a resonant amplitude of forced linear SDOF systems is explored. It is found that noise-induced excitations of the stiffness coefficient of the system can substantially reduce the amplitude of resonant vibrations. Three different sources of random noises with an exponential correlation function are used to demonstrate the effect.
