摘要
介绍了一种噪声变送器电流-声压级系统灵敏度校准方法及其不确定度评定过程,对允许误差换算进行符合性分析。校准结果符合要求,校准方法可行,为噪声变送器电流-声压级系统灵敏度的校准提供技术参考。
This paper proposes a method for calibrating the sensitivity of the current-sound pressure level system in an acoustic transducer.The uncertainty evaluation and a conformity nalysis of the conversion of permissible errors are also included.The desired calibration results were obtained,which can shed light on sensitivity calibration for acoustic transducers.
