This paper describes a method to reduce the propagation of bending waves by the occurrence of interference. In order to produce interference in the beam, it is necessary to reflect waves at two points on the beam. In this research, we proposed two methods to make reflection points: one method is to thicken a part of the beam, and the other method is to install a mass at each of two points on the beam. The governing equations were theoretically formulated using the modal analysis. The effectiveness of the proposed method was verified through simulations and experiments.
