摘　　要：扬声器的功率测试和标注,目前仍有标准欠明晰,术语定义欠准确的现象。在行业内的标准执行层面,或跟随标准更新不及时、或对标准理解各不相同、以至于测量方法不统一、测试信号不统一,功率标注不统一,给扬声器的选用和安全使用、给贸易中的交收检验都带来某些混乱。本文就这一问题提出看法,试图追本溯源,澄清一些模糊认识。The power testing and labeling of the loudspeakers,at present,the standard is not clear and the term definition is not accurate. At the standards implementation level in the industry,the standards are not updated in time,or the standards are not understood in the same way,so that the measurement method is not unified,the test singal is not uniform,the power labeling is not uniform,which brings some confusion to the selection and safe use of loudspeakers and the inspection in trade. This text puts forward some view on this issue,trying to go back to the source and clarify some fuzzy undestandings.
