DIN EN 61094-8:2013-04

This part of IEC 61094 is 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 calibrated laboratory or working standard microphone. 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.
