摘要
论述了传声器的应用和校准方法,重点对平面传声器动态特性校准方法进行了探讨,提出平面传声器的频率响应特性、幅值特性及指向特性的校准方法,并对校准结果进行了分析及验证。
The calibration method and application of the microphone will be described.A focus discussion of the surface microphone dynamic characteristics calibration method will be given.The calibration methods of the surface microphone will be developed,such as frequency response,linearity and directivity.The calibration results will be analyzed and verified.
