本文报告了一项关于在无触觉反馈情况下人类对手势声音控制的延迟容忍度的实验研究结果。16名受试者演奏了一台通过可调延迟缓冲器连接的特雷门琴。研究发现，与无延迟的参照相比，恰可察觉差异（JND）在20到30毫秒之间。在此之后，察觉到延迟的概率呈线性增加。还发现演奏风格对延迟的察觉有很大影响。在演奏带有颤音的慢节奏乐段时，即使是较高的延迟也未被察觉。研究结果还表明，年轻受试者比年长受试者更能准确地察觉延迟。然而，受试者的音乐活动及音乐背景似乎没有影响。
This paper reports the results of an experimental study of human latency tolerance for gestural sound control without tactile feedback. 16 subjects played a Theremin that was routed through an adjustable delay buffer. It was found that when comparing to a reference with no latency, the just noticeable difference (JND) is between 20 and 30 milliseconds. After that, the probability of detecting latency increases linearly. It was also found that playing style strongly affects the detection of latency. When playing slow passages with vibrato, even high latencies were not noticed. The results also suggest that younger subjects detect latencies more accurately than older subjects. However, the subjects’ activity with music and musical background did not seem to have an effect.
