説明
This paper deals with the inverse analysis method for estimation of the locations of noise sources. The noise sources located in three dimensional field are considered in this study. The sound intensity measurement method which takes account of the intensity and the direction of sound is used to find noise sources. The proposed procedure is formulated as an optimum problem to minimize the square sum of the residuals between the measured reference and trial sound intensities. The trial sound intensities are calculated by using boundary element method. The genetic algorithm is employed in this optimization and the proposed lattice investigation is subsequently applied to reduce computational efforts. Numerical calculations are carried out to demonstrate the effectiveness of the procedure. Furthermore, the identification of sound source locations can be performed in experiment.
