Abstract

An experimental comparison of output performances of human binaural system and correlation detector has been carried out. These phenomena are developed by detection of the tonal signals, masked by narrow-band noise, central at the signal frequency (fc) and having half-bandwidth deltafm=0.01 fc. The results are obtained with fc=800, 1000, 1500, 2000, 4000 and 6300 Hz. In these conditions the human binaural system may be discussed as correlation detector with the resolution: deltar=0.02 when fc less than or equal to 500 Hz and deltar=0.08 when fc more than or equal to Hz.

摘要

已经对人类双耳系统和相关检测器的输出性能进行了实验比较。这些现象是通过检测音调信号产生的,该音调信号被窄带噪声掩盖,以信号频率(fc)为中心,半带宽deltafm = 0.01fc。结果是在fc = 800、1000、1500、2000、4000和6300Hz的情况下获得的。在这些条件下,人类双耳系统可作为相关检测器进行讨论,其分辨率为:当fc小于或等于500Hz时,deltar = 0.02;当fc大于或等于Hz时,deltar = 0.08。 (注:原文中“when fc more than or equal to Hz”表述有误,可能是“when fc more than or equal to 1000Hz”之类,需根据完整准确原文进一步修正)
