Abstract: This paper deals with description of finite-amplitude standing waves in both closed and semi-closed resonators. Numerical solutions of second-order one-dimensional model equation are used. The nonlinear standing waves are generated by a piston or shaker. Numerical results of multifrequency driving technique for suppressing of higher harmonics are presented.
