3.78%。 The semi-free field wave superposition method and the free-field wave superposition method were utilized to calculate the acoustic sensitivity in the semi-free acoustic field. The simulated results show that the magnitudes and the change of the sensitivity by free field wave superposition method and the theoretical ones are widely divergent; but the results by semi-free field wave superposition method are consistent with the theoretical ones; the computing errors of the pulsating sphere source and the oscillating sphere source are 3.85% and 3.78% respectively.
