本技术规范规定了使用压力感应麦克风对声音强度进行测量的仪器的要求，包括其对电源和射频场以及静电放电的抗扰度，以及允许的射频发射，以及验证符合性的试验程序。声强测量仪器有许多不同的配置，可以由电池或外部电源系统供电。本技术规范中的技术要求适用于声强测量仪器的所有配置。 电磁和静电兼容性要求同样适用于住宅、商业和轻工业环境或工业场所中使用的声强测量仪器。本技术规范的要求是对IEC 61043中包含的要求的补充，不改变其中包含的任何规范。这些要求不适用于本技术规范发布前符合IEC 61043的声强测量仪器。

This Technical Specification specifies requirements for instruments that measure sound intensity using pairs of pressure sensing microphones with respect to their immunity to power- and radio-frequency fields and to electrostatic discharge, and the permitted radio-frequency emissions, together with test procedures to verify conformance. Sound intensity measuring instruments are available in many different configurations and may be powered by batteries or from external power supply systems. The technical requirements in this Technical Specification apply to all configurations of instruments for the measurement of sound intensity. The electromagnetic and electrostatic compatibility requirements are equally applicable for sound intensity measuring instruments used in residential, commercial and light-industrial environments, or industrial sites. The requirements of this Technical Specification are additional to those contained in IEC 61043 and do not alter any of the specifications contained therein. The requirements do not apply retrospectively to sound intensity measuring instruments complying with IEC 61043 prior to the publication of this Technical Specification.
