In this paper, the authors propose a new method for optimum design of bending grooves on vibrating panel-like structures to reduce noise. It is proposed in the method to use the mapping of sound pressure level on the panel's surface for best positioning of a groove and to apply the particle swarm optimization algorithm for determining the best dimensions of the groove. Then, an experiment is carried for a panel having a optimum designed bending groove to verify the varidity. It leads that the grooves designed by the optimization method can realize good reduction of sound power.
