标准摘要
[中文适用范围]: IEC 61094 系列的本部分适用于满足 IEC 61094-4 要求的工作标准麦克风。它描述了通过与已根据以下任一标准校准的实验室标准麦克风或工作标准麦克风(如果适用)进行比较来确定自由场灵敏度的方法: ?? IEC 61094-3@ ?? IEC 61094-2 或 IEC 61094-5@ 以及 IEC/TS 61094-7 中给出的因素已应用@ ?? IEC 61094-6@ ?? IEC 61094 的这一部分。在非常接近理想自由场(例如高质量自由场室)的声学环境中执行的方法,以及使用结果后处理来最大限度地减少缺陷影响的方法。 IEC 61094 本部分涵盖了声学环境@模拟自由场条件@。基于 IEC 61094-3 中描述的原理的比较方法也是可能的,但超出了 IEC 61094 本部分的范围。 注 1 IEC 本部分61094 还适用于满足 IEC 61094-1@ 要求的实验室标准麦克风,并指出这些麦克风还满足工作标准麦克风的电声规范。注2:IEC 61094的本部分也适用于麦克风和前置放大器的组合,其中确定的灵敏度是指前置放大器的空载输出电压。注3:其他设备@例如@声级计可以使用IEC 61094@本部分的原理进行校准,但不属于本标准的范围。 [外文原描述]: IEC 61094-8:2012 applicable to working standard microphones meeting the requirements of IEC 61094-4. It describes methods of determining the free-field sensitivity by comparison with a laboratory standard microphone or working standard microphone (where applicable) that has been calibrated according to either; IEC 61094-3; IEC 61094-2; IEC 61094-5; IEC 61094-6; or this part of IEC 61094. Methods performed in an acoustical environment that is a good approximation to an ideal free-field (e.g. a high quality free-field chamber), and methods that use post processing of results to minimise the effect of imperfections in the acoustical environment, to simulate free-field conditions, are both covered by this part of IEC 61094. Comparison methods based on the principles described in IEC 61094-3 are also possible but beyond the scope of this part of IEC 61094.
