摘要
基于LabVIEW和Matlab软件开发平台设计了传声器自由场互易校准数据处理系统,该系统可以有效提取电转移阻抗信号,计算声中心和灵敏度级,并通过软件测试证明了系统的可行性。
A DP system for free-field reciprocity calibration of condenser microphone is designed based on LabVIEW and Matlab.It can gain the electrical transfer impedance effectively,calculate the acoustic center and the sensitivity of microphones.The feasibility of the DP system is proved.
