Summary

This paper is concerned with a computer simulation for active control of duct noise by using the boundary element method available for analyzing three-dimensional acoustic field problems. The active noise control under consideration is reduced to an optimum problem to find an optimal set of parameters defining the vibrating state of a secondary noise source to be attached. A computer simulation system is developed, and computation is carried out for typical examples in which the duct is embodied in the infinite plane and the noise through the duct is radiated to the semi-infinite acoustic field. Then, an extension of the developed system is made to the noise source modeling.
