| 摘 要： | 根据阈值测量实验和变化一致性测量实验,在单自变量干扰和双自变量干扰两种情况下量化分析响度和谱质心之间的交互关系。研究发现:(1)复杂谐波信号中谱质心对响度的影响强于响度对谱质心的影响;(2)声音的变化方向对被试判断响度和谱质心的阈值存在影响。研究结果进一步呈现了响度和谱质心的定量特征,为听觉属性交互关系的深入研究提供了新的思路。

| Abstract: | To quantify the interactions between loudness and spectral centroid, the discrimination threshold and consistency of them both in single or bivariate mode are measured respectively, when they are changed in upward and downward. The results indicate that (1) the interactions between loudness and spectral centroid is asymmetry, i.e. the influence of spectral centroid to loudness is stronger than that of loudness to spectral centroid; (2) the discrimination thresholds of loudness and spectral centroid are different when the objective variable is changed upward or downward. The results presented the quantitative characteristic of interactions between loudness and spectral centroid, and offered suggestions on further research of interferences among the auditory dimensions. |
