SoRT is an integrated experimental/numerical technique for noise source identification in complex systems based on generalized Nearfield Acoustical Holography. SoRT allows noise source identification on planar and complex three-dimensional sources based on measurements taken in the neighborhood of noise sources. This tool can identify not only coherent noise sources but also multiple incoherent and partially coherent noise sources. The sources can be identified in free-field as well as in the presence of reflecting surfaces. The development of this module was partially funded by the National Aeronautics & Space Administration (NASA).
