1.1 本指南提供了包括可操作隔墙的建筑物设计中应考虑的设计细节。可操作隔墙是指那些可以快速放置到位或移除并存储的隔墙，以提供会议或社交活动通常使用的空间大小的灵活性。 1.1.1 本指南主要讨论了限制可操作隔墙周围声音泄漏所需的建筑设计细节。 1.1.2 该指南还讨论了影响分区本身性能的一些因素。 1.1.3 本指南既不是可操作隔板的规范，也不是旨在作为可操作隔板制造商要求的文件。 1.2 本指南不包括建筑产品行业分类为 可拆卸 . 可拆卸隔墙是指设计和安装的隔墙，其目的是在一段时间内由机组人员拆除和重新安装，并且组件可重复使用。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 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。 ====意义和用途====== 3.1 由可操作隔墙形成的房间通常需要隔音。可操作隔墙的隔声性能由建筑师根据隔声等级（STC）进行规定，并由制造商根据试验方法进行的实验室试验进行宣传 E90 和分类 E413 . 3.2 由于正常的建筑设计和施工实践与声学实验室中使用的不同，隔墙（包括可操作隔墙）的实际现场性能可能低于试样。 除可操作隔墙外，待隔离区域之间的声音传输将通过所有连接建筑构件发生，即楼板和天花板、天花板静压箱、公共墙等。被隔离区域之间的所有可能路径的隔音性能应至少等于可操作隔墙。除非在建筑设计和安装中都遵循良好的声学实践，否则预期的隔声效果与实现的隔声效果之间可能存在显著差异。 3.3 由于与可操作隔墙相邻的声音侧翼路径的复杂性，强烈建议由声学设计和施工方面的合格人员审查所有相关的施工细节。 3.4 本指南未规定要求。然而，希望编写安装和施工规范的人员可能会发现，这些内容有助于制定建筑设计现场准备的要求，以及减少可操作隔墙周围泄漏和侧翼声音所需的安装实践。

1.1 This guide provides design details that should be considered in the design of buildings that include operable partitions. Operable partitions are those that can be quickly put in place or removed and stored to provide flexibility in the size of spaces typically used for meetings or social functions. 1.1.1 The guide primarily discusses details in the building design required to limit leakage of sound around an operable partition. 1.1.2 The guide also discusses some factors that affect the performance of the partitions themselves. 1.1.3 This guide is neither a specification for operable partitions nor a document intended to be imposed as a requirement on manufacturers of operable partitions. 1.2 Excluded from this guide are those partitions that are classified by the building products industry as demountable . Demountable partitions are those that are designed and installed with the intent of later being taken down and re-erected by a crew over a period of time, with the components being reusable. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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. ====== Significance And Use ====== 3.1 Rooms formed by operable partitions often need to be isolated acoustically. Sound-isolating properties of operable partitions are specified by architects in terms of sound transmission class (STC) and so advertised by the manufacturer on the basis of laboratory tests in accordance with Test Method E90 and Classification E413 . 3.2 Because normal building design and construction practices are not the same as those used in acoustical laboratories, actual field performance of partitions, including operable partitions, will probably be less than that of test specimens. Sound transmission between areas to be isolated will occur through all of the connecting building components in addition to the operable partition, that is, floor and ceiling slabs, ceiling plenums, common walls, etc. All possible paths between the areas being isolated should have a sound insulation performance at least equal to the operable partition. Unless good acoustical practice is followed in both building design and installation, there may be a significant discrepancy between the sound isolation expected and that achieved. 3.3 Because of the complex nature of the sound flanking paths adjacent to operable partitions, it is highly recommended that all related construction details be reviewed by a person qualified in acoustical design and construction. 3.4 This guide does not specify requirements. However, persons desiring to write installation and construction specifications may find the contents useful in developing requirements for the building design site preparation, and installation practices necessary to minimize leakage and flanking sound around the operable partition.
