A study of the auditory response to transitions between signal frequencies

  • 摘要: 从探讨人耳在噪声背景中听测具有复杂时间-频率结构的主动声呐信号的模型出发,研究了人耳对信号频率发生短时间变化的听觉敏感性.根据在850—1130Hz频段内的测量结果,得出了人耳听觉对频率变化响应的模糊区域由τF=1—2决定,这里τ是频率发生变化的时间间隔,△F为频率变化的差值.当τF≤1时,人耳感觉不到频率短时间的变化;当τF≥2时,人耳不仅能明显分辨频率发生过短时间的变化,而且能对两个频率有不同的音调感觉。
    Abstract: For the study of detecting sonar signals with complex time-frequency compositions under a noise-background by human auditory system, the problem of auditory response to the transition between signal frequencies has been examined through a number of tests. According to the results of measurement within the frequency region of 850-1130 Hz, an equation (τΔF=1-2) to define the ambiguity region of responding to frequency transitions by human anditory system is found, where ΔF and τ are the difference and duration of the transition between two frequencies, respectively. When τ·ΔF≤1, the human auditory system hardly can sense the transition between two frequencies, however when τ·ΔF≥2,not only can clearly sense the transition but the diffrent tonalities of two frequencies as well.
