在使用多音掩蔽器的掩蔽实验中，相位效应通常与掩蔽器包络的强烈变化相关联。在这篇文章中，心理声学实验与这样的掩蔽物，导致相位依赖的阈值变化高达20分贝，虽然相位变换离开包络不变，进行了描述。然而，在用真实的基底膜模型过滤掩蔽物之后，由于模型的相位色散特性，包络是不同的。模型输出与实验结果的比较揭示了两者之间的强相关性的参数范围很广，提供了一个额外的假设，耳朵有一个最小的集成时间为几毫秒。
Phase effects in masking experiments using multitone maskers are usually associated with strong variations in the masker envelope. In this article, psychoacoustic experiments with such maskers that lead to phase-dependent threshold variations of up to 20 dB, although the phase transformation leaves the envelope unchanged, are described. However, after filtering the maskers with a realistic basilar membrane model, the envelopes are different owing to the models phase-dispersive properties. Comparison of model outputs with the experimental results reveals a strong correlation between the two for a wide range of parameters, provided one makes the additional assumption that the ear has a minimum integration time of a few milliseconds.
