GB/T 20441.8-2025 in English

This standard provides a method for comparing the free field sensitivity of working standard microphones used in electroacoustic measurements. It outlines procedures to ensure consistency and accuracy in determining the performance characteristics of these microphones. The document specifies the equipment, environmental conditions, and test procedures necessary for conducting the comparison. It also includes guidelines for handling and calibrating the measurement instruments involved. The standard is structured to support the calibration and verification processes within the field of electroacoustic measurements. It defines the requirements for the reference microphone and the test microphone, as well as the conditions under which the measurements should be performed. The content is organized to facilitate the implementation of the comparison method in laboratory settings.
