声强测量仪高声强级校准方法研究

Research on High Sound Intensity Lever Calibration Method of the Sound Intensity Probe

对声强测量仪校准方法的发展历程、现状及水平进行论述,重点对目前高声强级校准方法的研究进行描述,提出高声压源结合相位差的高声强级校准方法,使声强测量仪的声强级校准上限可达140dB。

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.
