Estimates the sound power level and sound energy level in an approximate free-field using an ellipsoidal measurement surface.
Need information includes: the x, y, and z coordinates of the microphone positions.
The sound pressure level and frequency information.
1) The Device Under Test (dut),
2) Background Noise (bg)
3) Reference Sound Source (rss) data with both the sound pressure level and frequency content.
The reference ellipsoid can be determined from the position and dimensions of the device under test (noise source).
Subprograms use MATLAB programs from the file exchange which are cited in the comments.
