| 摘 要： | 根据解释强度与强度JND关系的唯象模型 ,可得与ISO 1 3 1 1 979(E)同形式的响度变化模式 .也可得响度与响度JND间存在的关系 :响度JND与响度的比 (ΔL/L)是不依赖信号强度变化的常数 .响度与响度JND间的这种关系可从响度的听神经发放率表达机制得到定性的解释 .

| Abstract: | According to the model describing relation of intensity JND to intensity of tone, a loudness function with the same form as ISO 131 1979(E) and a relation of loudness JND to loudness were derived, which means the fraction of loudness JND to loudness was independent of intensity. This could be interpreted qualitatively by spike rate mechanism of loudness. |
