This part of IEC 61094-5 is applicable to working standard microphones with removable
protection grids meeting the requirements of IEC 61094-4 and to laboratory standard microphones
meeting the requirements of IEC 61094-1.
This part of IEC 61094 describes methods of determining the pressure sensitivity by
comparison with either a laboratory standard microphone or another working standard
microphone with known sensitivity in the respective frequency range.
Alternative comparison methods based on the principles described in IEC 61094-2 are
possible but beyond the scope of this part of IEC 61094.
