使用绝对识别范式测量了持续时间对复杂音调虚拟音高的影响。如果用单个中心频率编码噪声函数来表示双音复合体的性能，则发现该函数与纯音差阈值函数大致相同，依赖于持续时间。进一步发现，该函数对多音复合体的音高识别性能具有相当好的预测作用。另一个实验发现是，当复杂音调被缩短时，受试者倾向于切换到音调感知的分析模式（即，他们倾向于听到频谱音调而不是虚拟音调）。第三个发现是，对于同时出现的复杂音调，每个音高感知的退化不仅取决于音调的持续时间和和声顺序，还取决于另一个音调的和声顺序。
The influence of duration on the virtual pitch of complex tones was measured using an absolute identification paradigm. If performance with two-tone complexes is expressed in terms of a single central frequency-coding noise function, this function is found to depend on duration in about the same way as the pure-tone difference limen function. The function is further found to be a reasonably good predictor of pitch identification performance with multitone complexes. Another experimental finding was that subjects tend to switch to the analytic mode of pitch perception when complex tones are shortened (i.e., they tend to hear the spectral pitches instead of the virtual ones). A third finding was that with simultaneous complex tones the degradation of each pitch percept depends not only on duration and harmonic order of the tone but also on the harmonic order of the other tone.
