Scope
This part of GB/T 20441 specifies the primary method for determining the complex sound pressure sensitivity of laboratory standard microphones, establishing a reproducible and accurate basis for sound pressure measurement.
This part is applicable to laboratory standard microphones that meet the requirements of GB/T 20441.1—2010 and other types of capacitive microphones with the same dimensions.
All quantities in this part are expressed in units of the International System of Units.
