Specification for measurement microphones - Specifications for working standard microphones Ingestion-build-232773 Pipe manufacturers1 Scope and object This part of IEC 1094 is applicable to working standard microphones. It specifies mechanical dimensions and certain electroacoustical characteristics for working standard microphones used in measuring systems for the determination of sound pressure to enable these microphones to be used as transfer standards in the calibration of acoustic measurement instruments. It establishes a system for classifying working standard microphones
