ABSTRACT:
A method and system for mapping the acoustic near field of a stationary al symmetric structure are provided. The structure is subjected to a rotating excitation energy profile from a plurality of stationary excitation sites located radially around the structure. The acoustic near field of the structure due to the rotating excitation energy profile is measured along at least one line that conforms to a longitudinal surface of the structure. Mapping of the acoustic near field is complete when one rotation of the rotating excitation energy profile is complete.
