1.1 本规范规定了用于测量开放式办公室之间语音隐私和测量声学组件实验室性能的声源要求（见测试方法 E1111 和 E1130 ). 1.2 声源应为位于外壳内的扬声器，由适当的测试信号驱动。 1.3 本规范描述了声源以及使用特殊鉴定信号对其进行鉴定的方法。开放式办公室测试方法所需的测试信号可能不同。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification states the requirements for sound sources used for measuring the speech privacy between open offices and for measuring the laboratory performance of acoustical components (see Test Methods E1111 and E1130 ). 1.2 The sound source shall be a loudspeaker located in an enclosure driven with an appropriate test signal. 1.3 This specification describes the sound source and method of qualifying it using a special qualification signal. Test signals required by open office test methods may differ. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
