EN The article presents a new approach for noise reduction of a household washing machine. The noise sources and phenomenon were described. After investigation of a currently used solution, and alternative available solutions, a new approach was presented. Design and tests of a low costs magnetorheological fluid, semi-active damper were presented. The input parameters for the new damper were identified on the base of investigation of a viscous damper, used in washing machines. The described MR damper was applied in a washing machine suspension system. Next, a study of washing machine acceleration RMS for different unbalanced masses and durum rotations, were performed. During this research the new damper was switched on and off, to shows it influence on the acceleration. The end results show that the new designed dampers can strongly reduce the vibrations of the washing machine housing and its plastic components.
