Abstract

The irregularity coefficient of the frequency characteristics of masking effect is a function of the frequency of masking tone with constant intensity (10 dB SL). The coefficient is growing by 9--12 dB per octave of the masking tone reaching 60 dB at the frequency 10 kHz. Similar dependence was found by measuring the frequency threshold curves of the cochlear nerve fibers. These values of the coefficient could not be obtained with the aid of classical model of the cochlea.

摘要

掩蔽效应频率特性的不规则系数是恒定强度（10 dB SL）掩蔽音频率的函数。该系数随掩蔽音每倍频程增长9 - 12 dB，在10 kHz频率时达到60 dB。通过测量耳蜗神经纤维的频率阈值曲线也发现了类似的依赖性。借助经典的耳蜗模型无法获得该系数的这些值。
