摘　　要：一些传声器需要工作在160~190 dB的高声压下。本文介绍了用于高声压传声器校准的驻波管法、声流调制法、活塞发生器法、脉冲方法和激波管法的工作原理,比较了上述方法的优点和缺点,并根据国内外空气声计量发展的现状分析了空气声高声压校准技术的发展趋势,为高声压传声器的量值溯源和校准提供参考。Some microphones are working in high sound pressure from 160 dB to 190 dB.This article states the calibration method of these microphones,including the standing wave tube method,airflow modulation method,piston phone method,impulse method,shock tube method,etc.Advantages and disadvantages of these methods are compared,progresses of airborne high sound pressure calibration are analyzed based on progress of airborne high sound pressure calibration nationalwide and abroad.These can provide metrology reference to high pressure microphone.
