摘要


  1. 声品质主观评价方法中有基于成对比较的参考评分法,该方法在等级评分之前需要首先利用成对比较法对声音样本进行排序,设立参考噪声。该过程比较繁琐,劳动强度较大。本文提出通过建立人耳模型,对噪声样本按照声品质的不同属性实现粗略的分类排序,省去原方法中排序这一步骤,直接在每一类中设立参考噪声进行等级评分。本文选取燃料电池汽车8种行驶工况,24个噪声样本为例,介绍说明该方法的原理及有效性。




Abstract

Reference-Scale Estimation method based on paired comparison is one of sound quality subjective evaluation methods. This method need to use paired comparison method to sequence all of sound samples before Magnitude Estimation to establish standard noise sample. This process is very cumbersome with great labor intensity. In order to eliminate this step, this paper has proposed a human era model to achieve preliminary noise classification and establish reference noise sample in each category automatically. This paper has also chosen 24 noise samples from 8 driving cycle of Fuel Cell Vehicle (FCV) as examples to introduce the main theory and prove its effectiveness.
