1   Scope

This part of IEC 61094

• 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.
