Abstract
A system provides an in situ or non-invasive vibro-acoustic (VA) analysis of an arbitrary complex vibrating structure. The noise diagnostic system includes a plurality of first transducers for measuring acoustic pressure in a sound field near a noise source. At least one second transducer measures normal surface velocity on the noise source. A computer acquires acoustic pressure data from the plurality of first transducers and normal surface velocity data from the at least one second transducer. The computer generates a transfer matrix representing a correlation between normal surface velocity on the noise source and the acoustic pressure in the sound field.
