标准摘要
[中文适用范围]： IEC 1094的本部分适用于符合IEC 1094-1要求的实验室标准传声器。该方法的原理适用于其他类型的麦克风。特别是@当安装特殊适配器@时满足IEC 1094-1要求的麦克风@在移除适配器时也可以根据此标准进行校准。 IEC 1094的本部分规定了确定自由场灵敏度的主要方法，以便为自由场条件下声压的测量建立可重复且准确的基础。 IEC 1094 的这一部分旨在供拥有经验丰富的员工和专业设备的实验室使用。 [外文原描述]： Applies to laboratory standard microphones meeting the requirements of IEC 61094-1. The principles of the method are applicable to other types of microphones. In particular, microphones which fulfil the requirements of IEC 61094-1, when fitted with a special adaptor, may also be calibrated according to this standard when the adaptor is removed. Specifies a primary method of determining the free-field sensitivity so as to establish a reproducible and accurate basis for the measurement of sound pressure under free-field conditions. This publication supersedes IEC 60486.
