This paper is concerned with development of an effective computational procedure for noise source identification using boundary element software and one of the algorithms available for the optimum problems. The noise source identification in this study is formulated as an optimum problem to determine an optimal set of parameters which define the shape and the location of the noise source by minimizing the square sum of the residuals between the computed and measured quantities at selected points in the acoustic field. In this study, the acoustic intensity is used as the measured reference data, since the acoustic intensity is a vectoral value which includes information on both the intensity and the direction of sound. Use is made of the usual computer code based on the steepest descent method for the optimum problem under consideration. The acoustic intensity is calculated by the boundary element software previously reported on by the authors. Numerical experiments are carried out for a few sample problems using the computational software developed, and the usefulness of the proposed procedure is thereby demonstrated.
