标准范围

IEC 61094-3:2016规定了测定实验室标准话筒复自由场灵敏度的主要方法，以便为自由场条件下的声压测量建立一个可重复且准确的基础。适用于符合IEC 61094-1要求的实验室标准话筒。它适用于拥有经验丰富的工作人员和专业设备的实验室。第二版取消并取代1995年出版的第一版。本版为技术修订版。

IEC 61094-3:2016 specifies a primary method of determining the complex free-field sensitivity of laboratory standard microphones so as to establish a reproducible and accurate basis for the measurement of sound pressure under free-field conditions. It is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1. It is intended for use by laboratories with highly experienced staff and specialized equipment. This second edition cancels and replaces the first edition published in 1995. This edition constitutes a technical revision.
