利用基于人耳模型的声像图分析乐音的协和度

引入了人耳模型并计算其声像图来分析简单乐音的协和度．人耳模型模拟了人的心理和生理过程，通过该方法来寻找乐音的协和度与听觉客观机制之间的内在联系，使得主观感受和客观分析之间的联系更紧密．研究发现，稳定的和声音程具有稳定的声像图；声像图可以有效地判别简单乐音的协和程度，即简单乐音的协和度可通过声像图中纵向排列“整齐”的明亮条纹的数目以及相邻两明亮条纹间各阶分叉结构的数目来表征．

Analysis of Consonance of Musical Tone Based on Auditory Image Model

An auditory image model is established on the basis of previous physiological and psychophysical researches to reveal intrinsic relationship between physical hearing mechanism and subjective perception on consonance of musical tone.Study results show that auditory images derived by the model are highly correlative with subjective perception.A steady musical tone leads to a steady auditory image.Moreover,the consonance of musical tone can be described by the quantity of bright stripes and forked structures in auditory image.In short,the method proves efficient in evaluating consonance of musical tone.
