A numerical technique is developed to find and evaluate the optimal active noise controller in three dimensional cavities. The technique finds the volume velocity of multiple specified secondary sources which minimize a design objective function. The design objective function may emphasize either local or global control of the sound field. The noise sources in the cavity may be either compact or distributed. Results for global and local control in spherical and rectangular cavities are discussed.
