Anotácia textu normy IEC/TR 61094-10-ed.1.0 :

IEC TR 61904-10:2022 - is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of measurement microphones, - describes one possible absolute method for determining the complex pressure sensitivity, based on a device capable of generating a known sound pressure, especially at low frequencies, and - provides a reproducible and accurate basis for the measurement of sound pressure at low frequencies. All quantities are expressed in SI units.
