Measurement microphones - Part 8: Methods for determining the free-field sensitivity of working standard microphones by comparison

IEC 61094-8:2012 applicable to working standard microphones meeting the requirements of IEC 61094-4.

It describes methods of determining the free-field sensitivity by comparison with a laboratory standard microphone or working standard microphone (where applicable) that has been calibrated according to either:

  • IEC 61094-3;
  • IEC 61094-2;
  • IEC 61094-5;
  • IEC 61094-6;
  • or this part of IEC 61094.

Methods performed in an acoustical environment that is a good approximation to an ideal free-field (e.g. a high quality free-field chamber), and methods that use post processing of results to minimise the effect of imperfections in the acoustical environment, to simulate free-field conditions, are both covered by this part of IEC 61094.

Comparison methods based on the principles described in IEC 61094-3 are also possible but beyond the scope of this part of IEC 61094.
