Abstract: Calibration methods of the sound intensity probe, their present and history are described. A focus description of the high sound intensity level calibration method and example are given, the method which makes high sound pressure source combine with phase difference control is present, it could generate up to 140dB sound intensity level.

Key words: Sound Intensity Probe, Calibration, Sound pressure source, Phase difference
