Scope

1   Scope This part of International Standard IEC 61094 — is applicable to laboratory standard microphones meeting the requirements of IEC 61094‑1 and other types of condenser microphone having the same mechanical dimensions; — specifies a primary method of determining the complex pressure sensitivity so as to establish a reproducible and accurate basis for the measurement of sound pressure. All quantities are expressed in SI units.
