In this study, the practical method to locate the sound source positions on the noisy machinery is developed by use of the Nearfield Acoustic Holography (NAH). Generally, an actual machinery has a complicated shape combined several components spatially, so the source positions are distributed in the three dimensional field. It is proposed that a compact two-dimensional microphone array is moved and located around the source, and the reconstructed images are derived at each measurement position as the different view angles by the NAH modified due to the small measurement aperture. It is shown that the proposed methods are verified experimentally.
