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。
Provides a method to achieve high SPL approval using “double win negative pressure” in shock tubes. The method overcomes the shortcomings that the electrostatic characteristics of the microphone can only be given in the calibration of the high sound pressure level of the electrostatic excitation method. In this paper, the composition of the microwave tube system using the method, the experimental procedures and the preliminary results of the HC16 microphone are described.
