| Abstract: | A measurement method of the surface microphone for free field is described. The mathematic model of the surface microphone calibration system and evaluation of measurement uncertainty are analyzed. A real example for evaluation uncertainty is showed. The uncertainty of the calibration system is verified. The results are showed that the measurement uncertainty of the calibration system is reasonable and reliable. |
