An acoustic intensity probe was developed to measure waterborne sound intensity levels using a two-hydrophone technique. The technique utilizes the cross-spectral density of signals from multiple closely spaced hydrophones. Planar 2-dimensional and 3-dimensional arrays of hydrophones with symmetric and asymmetric configurations were developed to measure the acoustic intensity levels. This acoustic intensity probe combined with the two-hydrophone technique provides specific information revealing the acoustic energy distribution and propagation of noise sources in any acoustic environment.
