IEC/TS 61973:2012（E）适用于高压直流（HVDC）变电站户外可听噪声的规范和评估。主要供公用事业公司和顾问使用，他们负责发布新HVDC项目的技术规范，并评估潜在承包商提出的设计。它主要用于带有线路换流器的HVDC项目。本技术规范的一部分也可用于使用电压源换流器的HVDC项目，以及静态无功补偿器（SVC）和静态同步补偿器（STATCOM）等灵活交流输电系统（FACTS）设备。

IEC/TS 61973:2012(E) applies to the specification and evaluation of outdoor audible noise from high voltage direct current (HVDC) substations. It is intended to be primarily for the use of the utilities and consultants who are responsible for issuing technical specifications for new HVDC projects with and evaluating designs proposed by prospective contractors. It is primarily intended for HVDC projects with line-commutated converters. Part of this technical specification can also be used for the same purpose for HVDC projects using voltage sourced converters, and for flexible a.c. transmission systems (FACTS) devices such as static Var compensators (SVCs) and static synchronous compensators (STATCOMs).
