DESCRIPTION

DD IEC/TS 61094-7:2006


This standard DD IEC/TS 61094-7:2006 Measurement microphones is classified in these ICS categories:
  • 17.140.50 Electroacoustics
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.
