Abstract

Resolution of human auditory analyser to tine-impulse signals in the noise has been studied AX method was put in the basis of the experiment. Signals were the sinusoid intercepts. Relationships between probability of erroneous distinguishing of the signals and untuning, signal/noise and number of periods in the frequency range from 150 to 4800 Hz. It has been shown that the accepting auditory properties are invariants to the time transformations, the wave number of the sinusoid being the determining characteristics of the stimulus. A concept of frequency--time band of the auditory system is introduced. Its width according to the experimental data depends on the signal/noise ratio.

摘要

研究了人类听觉分析器在噪声中对齿脉冲信号的分辨能力。实验以AX方法为基础。信号为正弦波截段。研究了信号错误分辨概率与失调、信号/噪声以及频率范围从150至4800赫兹内周期数之间的关系。结果表明,听觉接受特性对于时间变换是不变的,正弦波的波数是刺激的决定性特征。引入了听觉系统的频率-时间带概念。根据实验数据,其宽度取决于信号/噪声比。
