An electroacoustic analogy is developed to analyze the open-circuit sensitivity, noise-canceling effect and frequency response of electret condenser microphones. In contrast to conventional models of electret condenser microphones in the literature, the present electroacoustic analogy analysis (E.A.A.) model details the open-circuit sensitivity, noise-canceling effect and frequency response of microphones. Two commercially available electret condenser microphones are analyzed to demonstrate the model. The results show that the calculating results of discussed microphones consist with the measuring data.
