标准摘要
[中文适用范围]: 本部分国际标准IEC 61094适用于符合IEC 61094-1要求的实验室标准麦克风以及其他具有相同机械尺寸的电容麦克风;规定了确定复杂压力灵敏度的主要方法,以便为声压测量建立可重复且准确的基础。所有量均以SI单位表示。 [外文原描述]: IEC 61094-2:2009+A1:2022 is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of condenser microphone having the same mechanical dimensions and 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. This second edition cancels and replaces the first edition published in 1992. This second edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - an update of Clause 6 to fulfil the requirements of ISO/IEC Guide 98-3; - an improvement of the heat conduction theory in Annex A; - a revision of Annex F: Physical properties of humid air.
