Locations of secondary sources in three-dimensional active noise control influence greatly on final control result. To find efficient secondary source sites for given primary source layout, an acoustic analysis of a three-dimensional interior space is done for low frequency ranges with low modal density. By using the boundary element method, magnitude and phase of optimum velocities of boundaries are evaluated for underdetermined system with an example of a rectangular box. Because the potential energy at mutiple field points depends on boundary velocity field,
