Scope
This part of GB/T 20441 specifies the method of determining sound pressure sensitivity by comparing with a laboratory standard microphone calibrated in accordance with IEC 610942:1992 or a working standard microphone calibrated in accordance with this part. This part is applicable to working standard microphones that meet the requirements of IEC 610944 and have removable protective grilles, as well as laboratory standard microphones that meet the requirements of IEC 610941 . The comparison method based on the principles described in IEC 610942:1992 is also feasible, but it is beyond the scope of this part.
