两种不同频率的音调，每秒交替5次。是以双耳的方式呈现给人类的。当频率差很小时，交替听起来像是音高的连续上下运动。当频率差异很大时，交替听起来像两个不相关的中断音。这两种感知组织之间的过渡点称为颤音阈值。颤音阈值被测量为频率的函数。在颤音阈值处，固定音调和匹配音调之间的频率差的大小直接随固定音调的频率而变化。
Two tones of different frequencies alternating successively 5 times/sec. were presented binaurally to human subjects. When the difference in frequency was small, the alternation sounded like a continuous up-and-down movement of the pitch. When the difference in frequency was large, the alternation sounded like 2 unrelated, interrupted tones. The transition point between these 2 perceptual organizations is called the trill threshold. The trill threshold was measured as a function of frequency. The magnitude of the difference in frequency between a fixed tone and a matching tone at the trill threshold varied directly with the frequency of the fixed tone.
