GB/T 19886-2005 in English

《GB/T 19886-2005声学 隔声罩和隔声间噪声控制指南》由TC17（全国声学标准化技术委员会）归口，主管部门为中国科学院。
本标准涉及用于噪声控制的隔声罩和隔声间的性能，它规定了声学和运行方面的要求，并要求隔声罩和隔声间的供货商或制造商同用户在这些要求方面达成一致。本标准适用于如下两类隔声罩和隔声间：a) 用于操作人员噪声防护的隔声间：独立隔声间和与机器(如车辆、起重机)相连的隔声间；b) 部分或全部罩住机器的独立隔声罩：本标准主要对象是未进行声学处理的敞口面积占总表面积小于10％的隔声罩。本标准重点适用于轻质结构，同时也适用于厚重结构(如砖墙)。未进行声学处理的敞口面积大于总表面积10％的隔声罩和隔声间属于部分围蔽结构范畴，不属于本标准研究范围。本标准不适用于构成机器一部分并且与之紧密相连的隔声罩。

Scope

This standard deals with the performance of acoustic enclosures and enclosures for noise control. It specifies acoustical and operational requirements and requires suppliers or manufacturers of acoustic enclosures and enclosures to discuss these requirements with users. agree. This standard applies to the following two types of sound enclosures and sound insulation rooms: a) Sound insulation rooms for noise protection of operators: independent sound insulation rooms and sound insulation rooms connected to machinery (such as vehicles, cranes); b) part Or independent sound insulation enclosures that completely cover the machine: the main object of this standard is the sound insulation enclosures whose open area accounts for less than 10% of the total surface area without acoustic treatment. This standard is mainly applicable to lightweight structures, but it is also applicable to heavy structures (such as brick walls). Sound insulation enclosures and sound insulation rooms with an open area greater than 10% of the total surface area without acoustic treatment belong to the category of partially enclosed structures and do not belong to the scope of this standard. This standard does not apply to sound insulation enclosures forming part of and closely connected to machinery.
