摘要提出了基于临界频带率、依赖于强度的扩展函数、非线性迭加和前向掩蔽效应的参数心理声学模型。

A parametric psychoacoustic model based on critical band rate, level - dependent spreading function, non - linear superposition and forward masking was proposed.

结果发现：掩蔽声对神经元放电率的抑制作用在时间上表现为前抑制（41%）、后抑制（9%）和全抑制（50%）三种类型。

We found that there were three types of inhibition period of neuronal firing, i. e. , early-inhibition(41%), late-inhibition(9%)and whole-inhibition(50%).
