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.
