IEC 61094-1 Ed. 2.0 b – Measurement microphones – Part 1: Specifications for laboratory standard microphones

Specifies mechanical dimensions and certain electroacoustic characteristics for condenser microphones used as laboratory standards for the realization of the unit of sound pressure and for sound pressure measurements of the highest attainable accuracy. The specifications are intended to ensure that primary calibration by the reciprocity method can be readily carried out. Establishes a system for classifying laboratory standard condenser microphones into a number of types according to their dimensions and properties.
