ASTM E1179-13(2019) PDF

Scope: 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.
