音质主观评价是一种模糊事件,用经典数学和统计来处理似较牵强。本文论述了评价的模糊性,提出了数学处理的初步方案,包括单项评语的模糊集合和综合评价的模糊集合,并提出各项评语对不同等级产品的贡献不同,须就不同等级产品给评语加以不同的计权。从几个例子看来这种处理方法是比较合理的,也是易行的。 Subjective evaluation of sound quality is a vague event, with the classical mathematics and statistics to deal with more far-fetched. This paper discusses the fuzziness of evaluation and puts forward the preliminary plan of mathematical processing, including the fuzzy set of single comment and the fuzzy set of comprehensive evaluation, and points out that each comment contributes differently to different grades of products. Different weighting. From a few examples, this approach is reasonable and easy to implement.
