使用“双腔负压法”实现激波管高声压级校准

Realizing the High Sound Pressure Level Calibration of a Shock Tube by "Double-Chamber Negative Pressure Method

提供了在激波管中使用“双胜负压法”实现高声压级核准的方法。该方法克服了静电激励法高声压级校准中只能给出传声器的电学特性的缺点。本文初步描述了使用该方法的微波管系统的组成、实验步骤以及对HC16传声器初步实验的结果。

The 'doublesichamber negative pressure method' in a shock tube system for high sound pressure level calibration is provided in this paper. This method can overcome the shortcoming in the high sound pressure level calibration by using electrostatic actuator method which only gives the electricity performance of the calibrated condenser. The composition of the shock tube system to employ this method and test steps are described briefly in this paper, meanwhile a preliminare experiment result of calibrating the condenser CH16 is also given.
