Abstract

The location of air leaks in plate‐like structures is examined using a spatial Fourier transform based analysis. Noise data is collected over 2‐D spatial arrays at sensor locations, from which mean cross‐correlations are compiled. Propagation properties, transit times, and energy distribution among modes are extracted through spatial Fourier transformation of these data. A simple algorithm to determine source location using a reduced set of transform data is demonstrated experimentally, based upon extraction of energy propagation direction.
