"声音质量主观评价用节目源标准样品"的论述

结合标准样品的基本概念,对节目源标准样品进行理论分析,并对几个主要的特性进行了介绍.电声产品和电声产品的声音质量(音质)是个心理量,它需要通过音质主观评价来获得结果,并用评价尺度来表示它的大小.同任何一个检测结果一样,音质主观评价结果同样必须具有溯源性和离散性这两个属性.标准样品的主要特性包括:溯源性、均匀性及稳定性、测量不确定度等.有证节目源国家标准样品的成功研制,对促进音质主观评价事业的技术发展和提高国内音响产品的音质水平具有重大意义.

Discussion on"standard sample of program source for subjective evaluation of sound quality"

Based on the basic concept of standard samples, the theoretical analysis of the program source standard samples is carried out, and several main characteristics are introduced.Acoustic products and electro acoustic products sound quality (quality) is a psychological quantity, which needs to get through the subjective evaluation of sound quality evaluation results, and scale to denote the size of it.As with any one of the test results, the subjective evaluation results of the sound quality must also have two attributes, traceability and dispersion.The main characteristics of the standard samples include: traceability, uniformity and stability, uncertainty of measurement, etc.The successful development of the national standard sample of the national standard has great significance to promote the technology development of the subjective evaluation of the quality and improve the quality level of the domestic audio products.
