本标准规定了标准声源的基本声学性能要求及其以1/1倍频带，1/3倍频带和A计权表示的声功率级的校准方法。本标准的附录A中描述了标准声源的几种型式。本标准适用于半消声室，即在一个反射面上的自由场声学环境内的校准，并规定了需要达到的不确定度的详细程度。本标准适用于各种型式的标准声源。

Scope

This standard specifies the basic acoustic performance requirements of the standard sound source and the calibration method of the sound power level expressed in 1/1 octave band, 1/3 octave band and A weighting. Several types of standard sound sources are described in Appendix A of this standard. This standard applies to calibrations in semi-anechoic chambers, ie free-field acoustic environments on a reflective surface, and specifies the level of detail of the uncertainty to be achieved. This standard applies to various types of standard sound sources.
