浅谈谱质心对弹拨乐单音悦耳度的影响

Discussion on the influence of spectral centroid to the euphony of Chinese plucked instruments

探讨了民族弹拨乐器声学特性的客观参数中,衡量能量分布的谱质心参数与主观听觉悦耳度之间的联系。挑选了一些常见的民族弹拨乐器的单音进行音质主观评价,利用多元统计分析方法将整理的主观评价数据与谱质心的客观参数进行拟合,较全面地了解谱质心对民族弹拨乐单音悦耳度的影响。对民族乐器客观分析研究做了初期探究基础,为专家学者广泛研究民族乐器声学领域提供参考。

Some Chinese plucked instruments＇ tones are chosen to study. Acoustic spectrum analysis software is used to measure the spectral eentroid, and appropriate experiments of subjective assessment of sound quality are designed.The rela- tionship between the euphony of Chinese plucked instruments and spectral centroid is studied in this paper.The data can help experts to analysis acoustic properties, but also promote more rational development of Chinese traditional Orchestra.
