Measurement Microphones – Part 7: Values for the difference between free field and pressure sensitivity levels of laboratory standard microphones

PUBLISH DATE 2021
ASA S1.15-2021/Part 7/ IEC TS 61094-7:2006
This part of IEC 61094 gives a polynomial function derived from a least square fit to data from several laboratories, for the differences between free field and pressure sensitivity levels of laboratory standard microphones as specified in IEC 61094 1; enables determination of the free-field sensitivity level of a laboratory standard microphone for zero-degrees incidence in air by adding values of these differences to the pressure sensitivity level; gives tabulated values for the polynomial function for a range of frequency and temperature; is applicable when a suitable free field calibration is not available.
