A simply supported beam of circular cross sections is assumed to be set into resonant oscillations by the action of a distributed external force. The oscillations generate sound. The aim of the present work is to determine the optimal radius distribution of the beam, which minimizes the emitted acoustic power, under constraints on the resonance frequency and beam volume. This optimization problem is solved numerically.
