In this paper, an optimality condition for the sound pressure minimization is considered. The sound pressure in the frequency domain is expressed by a scalar product of the structural frequency response function (FRF) and the acoustic FRF. Therefore, the optimality condition is that the amplitude of the sound pressure is zero when the structural FRF and the acoustic FRF are orthogonal. From this viewpoint, a contour plot which shows optimal state of the sound pressure minimization is introduced. And a novel optimization approach based on the optimality condition is proposed.
