Electroacoustics - Measurement microphones - Part 10: Absolute pressure calibration of microphones at low frequencies using calculable pistonphones
Abstract
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.
