Φ12.7mm测试电容传声器灵敏度的一种简易校准方法

A Simple Method for Calibrating the Sensitivity of Φ12.7 mm Condenser Microphone

没有专门的校准设备通常难以进行测试传声器灵敏度校准,这个因素限制了传声器的日常校准。充分使用实验室现有的设备,提出一种Φ12.7mm测试电容传声器灵敏度的简易校准方法,几乎具有专门校准设备的校准精度。

Generally,it is difficult to calibrate microphone sensitivity without special calibration instruments, which makes the maintenance of microphone can't be done frequently. A simple method that uses the common instruments in the laboratory to calibrate microphone sensitivity is presented. Furthermore, the calibration precision of this method is almost as good as that of the professional calibration instruments.
