提出了一种基于对播放时长短时化处理的声音样本剂量值度量方法,确定了十一种剂量值指标用于衡量具有固定播放时长声音样本的剂量值,并分析了可能影响声音样本剂量值的主要因素;随后,对大量声音样本以各种指标度量的剂量值矩阵进行了聚类分析,获得了三种类型的声音样本剂量值度量指标,并确定了不同指标类型中的代表性指标;最后,分析了声音样本采用不同类型指标度量的剂量值与评价者对声音样本主观烦恼度等级之间的关系.为利用主观评价实验进行固定播放时长声音样本作用下的主观烦恼度研究奠定了基础.
This paper proposes a method for measuring the dose of sound samples based on the short duration of playing duration. Eleven kinds of dose values are used to measure the dose values of the sound samples with fixed playing duration, and the influence of the dose values Then, a large number of sound samples were clustered based on the dose-value matrices measured by various indicators, and three types of sound sample dose-value metrics were obtained and representative indexes of different types of indicators were determined. Finally, the relationship between the dose values measured by different types of indicators and the appraiser’s subjective annoyance rating levels was analyzed, which laid the foundation for the subjective appraisal experiment to study subjective annoyances under fixed sound duration samples .
