Scope
This part of GB/T 20441 is applicable to working standard microphones. This part specifies the mechanical dimensions and electroacoustic characteristics of working standard microphones used in measurement systems to determine sound pressure. These microphones can be used as transfer standards in the calibration of acoustic measurement instruments. This part specifies the classification method of working standard microphones, which classifies microphones into several types according to their size and performance, so as to facilitate the standardization of measurement systems, the calibration of measurement systems and microphones with sound calibrators, and the interchangeability of microphones in measurement and calibration systems. This part does not explain the transduction principle of working standard microphones.
