We have developed a converted noise localization method, Converted Nearfield Acoustic Holography (NAH) method. This method can measure high frequency noise source with short measurement time. However, this method has some deterioration in the reconstructed images. In this paper, the experiments results of measurements for an engine are explained. As a result, it is verified that the proposing method can measure high frequency noise of engines quickly.
