ABSTRACT:
A computer implemented method and apparatus for identifying component breakdown of noise sources. Noise data is received for a noise source from an array of sound sensors. Measurement points of interest, candidate sound source points along an axis, and array aperture angles are identified. Sets of first and second bounding traces are identified from ray traces extending from the candidate noise source points towards the measurement points of interest using the array aperture angles. The bounding ray traces are rotated around the axis to form sets of first and second surfaces. Sets of first and second curves are identified from an intersection of the sets of first and second surfaces with the ground plane. Sound sensors are selected from the array using the curves to form subarrays. The component breakdown of noise generated by the noise source is identified using noise data from sound sensors in the subarrays.
